Laeveld se 20ste Herdenking
Soos almal in die Laeveldgemeenskap
weet, vier ons hierdie jaar ons 20ste
herdenking. Om dié verjaarsdag in
goeie styl te vier, het die hele Laeveld
familie en hul gesinne, sak-en-pak op
die sonnige hawe van Sun City in die
Pilanesberg neergedaal. Dit was 'n pret-
tige naweek, met aktiwiteite en vermaak
vir almal jonk en oud wat met ‘n skou-
spelagtige gala dinnee en toekennings-
geleentheid geëindig het.
Die algemene konsensus: Dit was 'n won-
derlike, luukse, glansryke en ontspan-
nende wegbreek vir almal.

3 - Elfranco MaréLimpopo Provinsie: Nylstroom, Vaal-
water, Alma, Tuinplaas, Roedtan en
Warmbad
Elfranco is in 1979 gebore en het op
Tuinplaas, op die Springbokvlakte,
as plaaskind grootgeword. Hy het sy
skoolloopbaan by die plaasskooltjie,
Laërskool Tuinplaas, afgeskop en ge-
matriekuleer by Hoërskool Hans Strij-
dom te Naboomspruit.
Met die sterk landbou-agtergrond van
‘n plaaskind en die opvoeding in ‘n
boeregemeenskap, besluit hy toe om
landbou te gaan studeer. In 2001 ver-
werf hy sy Landbou Diploma in Gewas-
produksie-bestuur en word aangewys as
die Beste Landboustudent van die jaar.
Na die voltooing van sy studies en
AVCASA akkreditasie, het hy sy toe-
trede tot die landbou chemiese bedryf
gemaak. Hy vestig hom op Nylstroom,
waar hy op die Springbokvlakte en
omgewing ondervinding opgedoen het
in verskeie landbougewasse en prak-
tyke. Die area leen hom veral daaraan
toe om te spesialiseer in “minimumbe-
werking-strategie" (no-till) en intensiewe
aartappel- en tabakverbouing. Hy het
besluit om by Laeveld Agrochem aan
te sluit, aangesien hulle reeks produkte
en tegniese ondersteuning beter gepas
is vir sy betrokkenheid by al die inten-
siewe besproeings-gewasse.
Volgens Elfranco:“Die landbou is nie net 'n liefde nie,
dis vir my 'n passie. Elke kliënt se
plaas voel soos my eie en daarom gee
ek my 100% vir elkeen van hulle. Dit
is 'n voorreg om betrokke te wees by,
na my mening, van die beste boere in
die land."

LAEVELD OP DIESILWERDOEK
D ie verfilming van die nuwe
Afrikaanse fliek, Platteland, het
Vrydag 9 Januarie 2011 in die Vry-
staatse dorp, Vrede, begin. Platteland
is geredigeer deur Philo Pieterse, wat
een van Suid-Afrika se mees bekendste
regisseurs is. Dié fliek is die breinkind
van Sean Else en Deon Opperman en
sluit 'n imposante groep Afrikaanse ak-
teurs in. Die twee hoofrolle word deur
Bok van Blerk en Lianie May vertolk,
maar mens kan ook vir Steve Hofmeyr,
Jay du Plessis, Vaughn Gardiner en
Karlien van Jaarsveld in dié fliek sien.
Platteland handel oor 'n boervrou wat
byna al’s verloor het en van voor af op
haar eie moet begin. Riana het onlangs
haar ouers in 'n tragiese en geheimsin-
nige vuur op hul plaas verloor en suk-
kel nou om kop bo water te hou terwyl
sy al haar skulde moet afbetaal ten
einde die familieplaas, Wonderfontein,
te behou.
Riana moet ook alles in haar vermoë
doen om te verseker dat die plaas nie
in die hande van die slinkse plaaslike
booswig, Mike Ferreira, beland nie.
Ongelooflike aksie volg soos wat al die
karakters saamkom in ‘n epiese stryd
vir familie, grond en liefde. L
Hier by Laeveld is ons passievol oor
die boeregemeenskap en die mense op
die Platteland, daarom het ons besluit
om as borg van die fliek op te tree.
Ons glo hierdie fliek gaan een van die
mees suksesvolste flieks in Suid-Afrika
se geskiedenis wees, en sal die rol van
die boer weer op 'n positiewe manier
uitbeeld. Vir dié rede wou Laeveld
graag sy volle gewig agter die projek
ingooi, en sal ons ook 'n spesiale weer-
gawe van die DVD aan al ons kliënte
beskibaar stel vanaf Februarie 2012.

Agtergrond
Mnr. Vorster, beter bekend as Vossie
onder sy mede boere, boer sedert
1971 op ’n deeltydse basis saam
met sy vader Mnr. JP Vorster op die
plaas Roodebank in die Standerton
omgewing. Gedurende 1982 koop hy
sy eie grond in die Bronkhorstspruit
omgewing en begin hy hom toespits
op vleismerinos as hoof bron van sy
boerderyinkomste.
Gou het hy besef dat as gevolg van
die hoë voerkoste, waarvan mielies die
grootste bydraer is tot die voerkoste,
hy selfvoorsienend in die proteïen be-
hoeftes van sy skaapboerdery sal moet
wees. Grond is egter ’n beperkende
faktor in die omgewing en is dit dus
van kardinale belang dat elke vierkante
meter optimaal benut moet word. Lam-
mers wat slag gereed is, word direk
van die plaas bemark en uitskot vee
word op veilings verkoop.
Mielie verbouing
Mielies word geplant deurgaans met
dieselfde stand, bemesting en kultivar.
Hy het geplant op 26/11/2010 met ’n
stand van 30 000 plante per hektaar,
maar as gevolg van droë toestande het
slegs 22 000 plante per hektaar gere-
aliseer. Daar is geplant met ’n kunsmis
mengsel van 2.3.2 (22) (+ 0.5% Zn oks-
ied) teen 150kg per hektaar.
Op 4 Jan 2011 na 202mm reën sedert
planttyd is daar opvolg bemesting met
KAN(28) teen 150kg per hektaar toe-
gedien. Zinchem is genader vir raad
aangesien die mielies sigbare tekort
getoon het. Die Zinchem verteenwoor-
diger het bepaal dat dit ’n sinktekort is.
Zinchem het aanbeveel dat 25kg per
hektaar Zn Sulfaat (korrels) ingemeng
word by sy KAN(28), maar dat ’n kon-
trole strook gelaat word. Na die bemes-
ting het nog 428mm reën geval voor

die fisiologies ryp word stadium van
die mielies. Gedurende die stadium het
Vossie gemerk dat hy geen visuele
verskil kan sien tussen die mielies wat
met Zn Sulfaat behandel is en die wat
nie behandel is nie.
Toe dit egter by strooptyd kom het
hy ’n merkwaardige 15,6% verbetering
in sy mielieopbrengs gerealiseer. Daar
is waargeneem dat oor die algemeen
die mieliekoppe wat met sinksulfaat
behandel is 12 rye per kop het en
ongeveer 340g geweeg het. Dit terwyl
die mieliekoppe op die onbehandelde
strook eerder 10 rye per kop gehad
het en ongeveer 270g per kop geweeg
het en ook meer Diplodia (kopvrot)
gekry het as die mielies wat met sink-
sulfaat behandel was.
Wat merkwaardig is, is dat die sink-
sulfaat wat op die laatstadium ongeveer
4 weke na opkoms (topbemesting-
tyd) nog steeds sulke goeie resultate
gelewer het. Zinchem is van mening
dat dit toegeskryf kan word aan die
produk se 100% wateroplosbaarheid.
Die mielieplante kon dus die sink kort
nadat dit toegedien is in die grond
deur die wortels opneem en benut vir
groei en ontwikkeling.
Mnr. Vorster sê "Ek is oortuig dat
Zinchem se Zn Sulfaat beslis die
toekoms vir my boerdery is en sal
ek dit ter enige tyd aanbeveel by
medeboere. Waar ek vroeër die jaar
’n potensiele tekort aan mielieproteïen
in die gesig gestaar het, en teen ’n
addisionele koste mielies sou moes
inkoop, gaan die groot verbetering op
my oes in ’n kritieke stadium, weens
Zinchem se Zn Sulfaat, my in staat stel
om genoegsame mielies te stroop om
aan my behoeftes te voorsien”.
Zinchem het ’n rygewasse grondtoedien-
ing multimikro-element produk ontwikkel
wat bestaan uit ’n volledige reeks
essensiële mikro-elemente wat met
planttyd toegedien kan word. Sodoende
kan beter saailing groei verkry word
deur die verskaffing van onmiddellik
beskikbare essensiële mikro-elemente
om ten minste gedeeltelik omgewings
geïnhibeerde toestande te oorbrug.
Die doel van die produk is nie om die
hele gewas te voed nie, maar slegs om
’n goeie wegtrek te verseker, m.a.w.

’n goeie wortelstelsel in plek te sit. ’n
Goed ontwikkelde wortelstelsel sal die
plant help om beter aan sy vog en
voedingsbehoeftes te voorsien en minder
gevoelig te wees vir ongunstige grond-
en omgewingstoestande. Die rygewasse
grond toedienings multimikro-element
produk kan jaarliks gebruik word om
te voorsien aan die rygewasse se mik-
ro-element behoeftes.
Dit is ’n goeie praktyk om grondontled-
ings te trek wat ook die mikro-elemente
ontleed, sodoende kan ’n plan van aksie
gemaak word van hoe om die mikro-
elemente te bestuur. Voorkoming van
tekorte is beter as krisis bestuur waar
tekorte visueel waargeneem word en
daarop gereageer word. Zinchem kan
help om mikro-element behoeftes aan
te spreek sodat u meer winsgewend
en volhoubaar kan bly boer. Daar kan
net eenvoudig nie bekostig word om
nie die volle potensiaal van u gronde
te ontgin nie. Hoekom alles reg doen
soos die regte makro elemente, kalk,
kultivar, bewerking en insek en onkruid-
beheer doen, maar essensiële mikro-
elemente ignoreer wat kan help om u
gronde se volle potensiaal te bereik.
Kontak jou naaste Laeveld Agrochem
gewasbeskermingsdeskundige om te
help met die bereiking van u boerdery
se volle potensiaal deur die aanspreek
van u mikro-element behoeftes. L

Farmingmay ensure
food securityin Orange farm
To ensure food security in Orange Farm, residents have said they need assistance with agricultural skills training, equipment, and access to the abundant fertile land, and
would then be able to produce their own food.
LAEVELD Summer/Somer 2011 - 13
T his appeal came from residents
during a consultative meeting on
the City’s Growth and Development
Strategy public participation process,
GDS2040, in August at the Orange Farm
Multipurpose Centre. At the meeting,
themed “Food safety and food secu-
rity at the urban fringe”, the community
voiced suggestions about what the City
could do for them to ensure sustainable
food production.
Residents of the poverty stricken Orange
Farm, some 50km from the Johannesburg
CBD, rely on small-scale farming to
feed their families, such as backyard
food gardens. A small number of them
are in larger scale farming.
Thabo Matshidiso, a resident and a
small-scale farmer, said the community
was poor and could not afford to buy
food from supermarkets. “At the mo-
ment it is hard for us to venture into
large-scale farming because we do not
have the land and required skills. Most
people are unemployed and can’t af-
ford to buy expensive food.
“There are 130 hectares of unutilised
land on the outskirts of Orange Farm.
It can be used to plough vegetables or
for livestock farming. This will allow our
people cheap access to quality food.”
He suggested that the city provide
skills training for emerging farmers.
Farming has changed over the years,
so it is important for farmers to keep
up with the modern ways as they are
more effective and affordable.
Sipho Mbele, an aspiring farmer, said
he had been applying for permission
for livestock farming, without success. “I
think the City should get down to the
ground and address our needs. There
are a lot of unemployed young people
who are ready to venture into agricul-
ture and farming; all we need is to be
trained.”
Responding to the concerns, Molwele
said the people of Orange Farm were
ready to make a difference in their
community and that the City would go
all out to meet them halfway. “We are
going to work together with this com-
munity to alleviate poverty and we will
sit down with the executive mayor and
come up with solutions to issues raised.”
Laeveld is always happy to aid and
assist subsistence farmers to become
self-sufficient in the supply of food
products. L

Adjuvants:Lending a Helping Hand
T he water molecule has a high sur-
face tension and this leads to for-
mation of water droplets when sprayed
on a waxy surface. This results in pesti-
cides not being able to spread evenly,
leaving an irregular coverage resulting
in higher use of pesticides. A spray
drop must be able to wet the foliage
and spread out or cover an area of
the leaf for the pesticide to perform its
pest control function. The adjuvant acts
here by reducing the surface tension of
the water on the surface of the spray
drop and by reducing the interfacial
tension between the spray drop and
surface of the leaf.
Types of Adjuvants and their Functions
BUFFERS
Problem
Insecticides like the organophosphates,
pyrethroids and various other products
are degraded by spray water with
a high pH. The degradation process,
known as alkaline hydrolysis, begins
when the product is mixed with the
spray water and ends once the spray
droplet has dried out. The efficacy of
the pesticide is reduced because a
sub-optimal rate is applied. Most South
FEATURE:ADJUVANTS
16 - LAEVELD Summer/Somer 2011
In agriculture, an adjuvant is broadly defined as any substance added to the spray tank, (separate from the pesticide formulation) that will improve the performance of the pesticides, herbicides, feeding stimulants etc.
African water sources have high pH
values (between pH 6.5 and pH 9.0)
and therefore create an environment
for alkaline hydrolysis.
Solution
In certain cases, pesticide labels recom-
mend the acidification of spray solu-
tions to limit alkaline hydrolysis. Villa
offers a solution to this problem with
effective products that buffer spray wa-
ter pH between pH 4.5 and pH 6.0
(the ideal pH for insecticide efficacy).
These buffers protect the insecticide
against alkaline hydrolysis and there-
fore improve insect control.
Products: Commodobuff, Aquabuff and
Buffernat
SALT ADJUVANTS
Problem
Water always contains a certain amount
of dissolved salts like calcium, magne-
sium and sodium (hard and brackish
water). These salts bind to herbicides
like glyphosate and decrease absorp-
tion and efficacy. The decrease in
glyphosate efficacy as a result of salt
antagonism depends on water volume,
herbicide rate and conditions during
and after spraying.
The absorption and efficacy of many
herbicides is influenced by environ-

control. The efficacy of herbicides like
paraquat can be increased by using
activator adjuvants.
Solution
Villa offers a solution to salt antagonism
in the form of quality adjuvants. These
adjuvants have the ability to neutralize
antagonistic salts before they can react
with the glyphosate. This ensures effec-
tive weed control with glyphosate, even
with water that contains high salt lev-
els. Summit is an activator adjuvant that
increases the efficacy of herbicides
like paraquat. It reduces the detrimen-
tal effect of the environment on the
herbicide and increases the chance for
successful weed control. Summit is new
generation, patented technology and is
the first product of its kind on the
South African market.
Products: Summit and Velocity-Dry
SURFACTANTS
Problem
To be effective, pesticides must be
spread and retained on the target and
in the case of systemic products, must
then be absorbed by the plant tissue.
Spray droplets without surfactants are
prone to deflection off the leaf surface
and do not spread effectively. This has
a negative impact on pesticide efficacy.
It is crucial to use the correct surfactant
to improve pest control.
Solution
Villa 51 has properties that reduce drop-
let deflection, and increase spreading
and absorption of pesticides. This im-
proves pest control over a wide range
of conditions.

FEATURE:ADJUVANTS
OIL ADJUVANTS
Problem
Favourable conditions and slow evapo-
ration of droplets is needed for pes-
ticides to be absorbed effectively.
Environmental conditions such as low
humidity can be sub-optimal during
and after spraying. This may inhibit
pesticide performance. In cases like
this, it is essential to use an adjuvant
that creates conditions that are optimal
for absorption and efficacy.
Solution
Ag-Penetrex and Solitaire are both oil
adjuvants that are designed to over-
come the above-mentioned conditions.
These adjuvants reduce the effect of
the environment on pesticides and
create ideal conditions for pesticide
absorption.

ADJUVANT TIPS
• Remember there is no universal
adjuvant. Use the correct product for
a specific purpose.
• Adjuvants stabilise pest control under
a range of conditions. Adjuvants do
not act as an insurance policy against
unregistered applications
• The effect of water quality can be
controlled and managed by utilising
the correct information and adjuvant
technology. L

EPIDEMICS &OUTBREAKS
Seasonal Conditions Drive Outbreaks
S tem rust is caused by the fungus
Puccinia graminis. When conditions
favour a stem rust epidemic, it can be
a very damaging disease that can cause
complete crop loss in susceptible wheat
varieties. The introduction of resistant
varieties and a greater range of effective
foliar fungicides have helped to reduce
the impact of stem rust in recent years.
Outbreaks have been confined to a few
localised occurrences. However, the
combination of a wet spring, susceptible
varieties and inoculum build-up on vol-
unteer cereals can result in an outbreak.
Resistant wheat varieties have reduced
the incidence of stem rust outbreaks
but on-going vigilance is needed to
prevent the pathogen mutating to over-
come this resistance.
What to look forStem rust is characterised by reddish-
brown, powdery, oblong pustules that
can affect all parts of the plant. The
pustules have a characteristic torn mar-
gin and can occur on both sides of the
leaves, on the stems and the glumes.
Stem rust spores are much darker in
colour than leaf rust spores. As the
wheat plant matures, the pustules pro-

duce black spores known as teliospores.
These occur mainly on the leaf sheaths
and stem. Rust spores are wind-blown
and can be spread over large areas in
a short time. Stem rust usually becomes
evident later in the season than stripe
rust; warmer weather accelerates the
spread of the disease.
Conditions That Favour Stem Rust
Stem rust can occur in all grain grow-
ing regions where susceptible varieties
are grown. However, there are several
key factors that will increase the likeli-
hood of a stem rust epidemic.
The amount of stem rust present in the previous season: The more stem rust in
a given year, the greater the likelihood
of carry-over into the next season.
Summer and autumn rains: Summer
rain will allow volunteer cereal hosts
to flourish, creating a green bridge to
carry the rust from one season to the
next. Autumn rains will support the early
build-up of rust on volunteer cereals.
Favourable weather conditions during the current growing season: Seasonal conditions that favour the outbreak of
stem rust include spring rain and warm,
humid weather. The combination of a
wet spring, susceptible varieties and
inoculum build-up on volunteer cereals
is likely to result in an outbreak. Infec-
tion generally occurs when tempera-
tures are in the 15˚C to 30˚C range.
Pre-season management of stem rust: Stem rust can be managed using
an integrated approach. This includes
reducing the amount of inoculum in a
district by managing the green bridge,
avoiding susceptible cultivars and
closely monitoring crops with a view to
fungicide applications.
GREEN BRIDGE
Rust can only survive from one season
to the next on living plant material
(mainly self-sown cereals). It does not
survive on stubble, seed or soil. The
most important hosts are susceptible
wheat, but it can also survive on barley,
triticale and some grasses. Removing
the green bridge, including volunteer
cereals, is essential to reduce the
amount of inoculum present that could
infect the following crop. Stem rust
epidemics have been worse in years
where wet summers/autumns favoured
volunteer cereal growth.
Variety selectionSowing resistant varieties provides the
best protection against stem rust. Vari-
etal resistance to stem rust pathotypes
has remained stable during the past
five years. Stem rust occasionally pro-
duces new pathotypes (races) that are
capable of attacking resistant varieties.
22 - LAEVELD Summer/Somer 2011
The risk of a new pathotype develop-
ing increases the more often outbreaks
occur. New pathotypes occur when a
chance mutation occurs in this asexu-
ally reproducing fungus. Using resistant
varieties minimises the amount of rust
in a district and reduces the chance of
new pathotypes occurring. It is impor-
tant that growers are aware of a vari-
ety’s resistance reaction to stem rust.
Consult a current wheat variety guide
when selecting cultivars for stem rust

management to check the susceptibility
rating. As new rust pathotypes can de-
velop, the rust reaction or cultivars can
change with time and older disease
guides may no longer be relevant.
Yield lossPotential yield loss depends on the re-
sistance rating and how early the dis-
ease starts in the crop. Stem rust is most
severe in susceptible varieties when it
begins to develop in the crop before
flowering. Yield losses from later infec-
tions are possible, but not as severe.
In-crop Management of Stem Rust
Monitoring• Volunteer plants should be moni-
tored during summer and particu-
larly before sowing.
• Crops of susceptible varieties
should be inspected every seven
to 10 days in seasons when stem
rust has been detected in a region
and more frequently from flag leaf
emergence to when grain is at the
early dough stage.
• Carefully inspect different plant
parts, including the lower stems, for
symptoms of stem rust.
• Inspect different areas of a paddock
including where crops are thicker.
Fungicide treatmentsThe effects of stem rust can be mi-
nimised with the timely application of
foliar fungicides. The earlier fungicide
is applied the more effective it is in
controlling stem rust. In susceptible
wheat cultivars fungicides need to be
applied as early as possible in the de-
velopment of the disease and prefer-
ably as a preventive treatment, to avoid
potential yield losses and restrict the
spread of the disease. To be effective,
fungicides should also be applied at
the highest registered rate. If the stem
rust outbreak occurs late in the season
(for example, after mid-dough) and the
level of infection is low there will be
little impact on yield and no economic
benefit from fungicide treatments.
Choice of fungisideThere are a number of active ingredi-
ents available in a range of products,
registered for the control of stem rust.
For this reason it is critical to contact
your Laeveld Agrochem crop protec-
tion expert to ensure that you get the
most suitable solution for your specific
needs. L
Take Note: Always read the chemical
label before use. Make sure that the
product is registered for use in your
province. Use the maximum recom-
mended label rate for stem rust control
in wheat. As sprays for stem rust may
be applied late in the season, it is ex-
tremely important to know the harvest
withholding period for the chemicals,
which can vary from four to six weeks.

D ie Suid Afrikaanse sitrusbedryf is
die tweede grootste uitvoerder van
vars sitrus in die wêreld naas Spanje.
Dit alleen is ’n merkwaardige prestasie
aangesien Suid Afrika maar die 14de
plek in globale sitrusproduksie beklee.
’n Totaal van 64 persent van alle sitrus
in Suid Afrika is bestem vir die uitvoer-
mark, dus is die suksesvolle produksie
van bemarkbare vrugte vir die uitvoer-
mark van kardinale belang vir die Suid
Afrikaanse sitrusbedryf.
Daar is verskeie faktore wat die be-
markbaarheid van uitvoervrugte kan
beïnvloed waarvan insekskade een van
die belangrikste is. Heelwat plaagbe-
heermiddels is beskikbaar om verskeie
insekprobleme aan te spreek, maar
onoordeelkundige gebruik kan ly tot
sekondêre pes uitbrake en onaanvaar-
bare residu vlakke wat die bemark-
baarheid van die vrugte kan beïnvloed.
Die keuse van plaagmiddels moet so
gekies word dat dit ’n minimale nega-
tiewe impak op die bemarkbaarheid
van die vrugte het. Movento® (spirotet-
ramat) is so ’n produk en word wêreld-
wyd erken as ’n leier produk wat nie
die bemarkbaarheid van vrugte nega-
tief beïnvloed nie.
Movento® bied die sitrusprodusent
en uitvoerder die geleentheid om ’n
produk te gebruik met uitstekende
dopluisbeheer (Fig. 1) wat hoë gehalte
opbrengste verseker.

Verder het dit ‘n minimale impak op
voordelige insekte. Aangesien Moven-
to® tot die groep middels van die tet-
ramiese sure behoort is dit die ideale

word. Die toediening van Movento® kan
enige tyd plaasvind sodra dopluis krui-
perbeweging waargeneem word. Dit
laat die gebruiker van Movento® toe
om ’n pasmaak spuitprogram te beplan
sonder enige addisionele trekkerbewe-
ging in die boord.
Movento® is ’n blaarbespuiting wat
bestuur en gemak van ‘n spuitprogram
bevorder. Die impak op die omgewing
is ook minimaal deurdat daar minder
aktief per ha toegedien word as van
die ander produkte wat teen dopluis
gebruik word. Die toksologiese profiel
van Movento® is van so ’n aard dat
dit selfs goedgekeur is vir gebruik op
vrugte/groente bestem vir babavoedsel
in die VSA.
Die keuse van Movento® as ‘n be-
sigheidsbesluit is onder kommersiële
boorde bewys gedurende die afgelope
seisoen. Ter illustrasie hiervan is 2.63%
beter uitpak verkry in die Movento®
behandelings as in blokke met ‘n al-
ternatiewe dopluisbeheerprogram (Fig.
2). Die beter uitpak was nie alleen
as gevolg van ’n verlaging in uitskot
weens dopluisskade nie maar ook laer
witluis en blaaspootjie uitskotte.
Fig. 2.
Hierdie tendens kan moontlik toe-
geskryf word aan die verminderde im-
pak wat Movento® het op voordelige
insekte wat ’n rol speel in die biolo-
giese beheer van die ander peste. Die
Movento® program was ook R1000 per
hektaar goedkoper waar die verskil
tussen die twee programme toegeskryf
kan word aan addisionele behande-
lings om sekondêre peste soos myte
te beheer.

R hizoVital is a liquid concentrate of
the beneficial bacterium Bacillus
amyloliquefaciens. This is a naturally
occuring soil bacterium that forms close
associations with plant root systems and
produces various compounds that have
plant growth-regulating properties. This
results in improved germination, root
growth and vigour. Through this asso-
ciation it colonises the root zone which
has the subsequent benefit of providing
protection from pathogens through com-
petitive displacement and also activates
the plants SAR, thereby reducing the
frequency and severity of common soil
diseases.
BENEFITS
• Improved germination and increased
vigour
• Improved rooting after transplant
• Improved general root health and
increase in shoot growth
• Improves mobilisation and absorption
of soil nutrition, notably Phosphate,
Zinc and Manganese
• Improves performance of Mycorhizial
fungi
• Reduced disease intensity & frequency

D ie abnormale weersomstandighede
tydens die 2010/2011 mielieseisoen
het meer druk geplaas op algemene
boerdery bestuurspraktyke. Een van die
gevolge was dat swamdoder bespuit-
ings nie tydens die optimale toedie-
ningsvenster plaasgevind het nie, met
gevolglike hoër siektedruk wat dan
moeiliker met kuratiewe bespuitings
beheer moes word. Die uitkoms was
duidelik dat die fokus moet verskuif
vanaf ‘n tradisionele siektebestuurspro-
gram, na ‘n voorkomende opbrengs-
bestuursprogram.
Tradisionele siektebeheer was gebas-
seer op kuratiewe bespuitings, wan-
neer die eerste siektesimptome op die
blaar reeds sigbaar is. Navorsing toon
dat wanneer hierdie eerste letsels sig-
baar is, soveel as 10% oesverlies reeds
plaasgevind het. Kuratiewe bespuitings
het ook tot gevolg dat bespuitings met
korter intervalle moet plaasvind, aan-
gesien die aktiewe bestanddeel gebruik
word om die siekte te beveg en dus
nie genoeg residuele werking bied vir
siektebeskerming nie.
Skade het reeds plaasgevind teen die
tyd wanneer die siekte sigbaar is:
• Die plant gebruik sy energie om
die swam te beveg.
• Die nawerkingsperiode van ‘n
swamdoder wat kuratief toegedien
is word verkort.
• Opbrengspotensiaal word verminder
aangesien die plant sy energie nie
kanaliseer na interne fisiologiese
prosesse soos die vaslegging van
kopgrootte en pitte nie.
Gegewe die mees belangrike mielie-
blaarsiektes wêreldwyd, is dit ongeluk-
kig dat Suid Afrika die totale spektrum
het: Noordelike blaarskroei, Grysblaar-
vlek, Roes en Phaeosphaeria. Hierdie
siektes neem toe in intensiteit en wis-
sel volgens klimaatstoestande en tussen

FINANSIËLEFOKUS
G edurende die afgelope jaar was
landboumarkte wêreldwyd aan-
sienlik wisselvallig soos die balans
tussen vraag en aanbod gewissel het
weens verskeie eksterne-faktore. Ou-
dergewoonte het Moeder Natuur nat-
uurlik in die vorm van ongure weers-
toestande haar gewig rondgegooi en
veroorsaak dat produksie in sleutel-
produserende lande soos Rusland
skerp afgeneem het. Dit het uitsonder-
lik lae voorraadvlakke vir veral grane
op internasionale vlak tot gevolg ge-
had. Verder het ekonomiese groei in
Oos-Europa, Asië en Latyns-Amerika
die vraag na voedsel en energie ge-
dryf en veroorsaak dat voorraadvlakke
verder onder druk geplaas is. Die ver-
wantskap tussen landbou-kommoditeite
en energiemarkte is sterker as ooit
(byvoorbeeld toename in mielies wat
vir bio-etanol vervaardiging gebruik
word asook brandstof en kunsmis in
graanproduksie) en gevolglik bring dit
verdere wisselvalligheid in die land-
boumark mee. Ekonomiese groei in
lande is dus een van die belangrikste
dryfkragte in landboumarkte. Huidiglik
verhandel pryse bo die hoogtepunte
van 2008. Onderliggende redes vir hier-
die situasie is die feit dat voorraad as
persentasie van verbruik (“stock-to-use
ratio”) op historiese laagtepunte is, en
die verwagting is dat die vraag in die
2011/2012 seisoen steeds die aanbod
oorskry. Die hoë pryse wat huidiglik
realiseer sal egter vraag na somer-
grane effens demp en gevolglik kan ‘n
effense daling in pryse gedurende die
2011/12 seisoen verwag word.

Huidige stand en vooruitsigte vir die Suid-Afrikaanse mieliemark
Lae pryse gedurende die 2009/10 sei-
soen het meegebring dat produsente
minder geplant het in 2010/11. Die area
onder witmielies het met 18% verminder
na 1.4 miljoen ha, terwyl geelmielies met
7% verminder het na 954 000 ha. Die
laer produksie tesame met hoë uitvoer-
vlakke het gevolglik meegebring dat
die totale mielie-eindvoorraad na 1.2
miljoen ton afgesak het (950 000 minder
as in 2010). Binnelandse mieliepryse
het wêreldpryse gevolg en wys ‘n op-
waartse kurwe vir 2011, met ‘n jaar-
likse mielieprys in die omgewing van
R 1 900/ton. In September het wit en
geelmielies gemiddeld teen R 2 215/ton
en R 2 185/ton onderskeidelik verhandel
wat sowat 72% en 59% hoër is op ‘n
jaar-tot-jaar grondslag vir die twee ge-
wasse (Tabel 1).
Hierdie styging in die mielieprys sal na
verwagting mielieprodusente aanspoor
om hul mielie-aanplantings uit te brei
in die komende (2011/12) seisoen met
totale mielieaanplantings van sowat 2.7
miljoen hektaar. Huidiglik hou lae in-
ternasionale mielievoorrade mieliepryse
hoog en indien die vraag na grane
vasstaan, kan huidige hoë pryse in
2012 realiseer. Die hoër aanplantings
en gevolglik produksie wat met hoë
pryse gepaardgaan sal weer meebring
dat mieliepryse vanaf 2012 sal daal.
Mielie-aanplantings deur produsente
sal hierop reageer en die verwagting
is dat die area onder mielies op so-

wat 2.5 miljoen hektaar sal konsolideer.
Oor die langtermyn word egter beraam
dat mieliepryse gemiddeld sal toe-
neem weens hoër internasionale pryse
en verswakking van die Rand/Dollar
wisselkoers. Die hoër internasionale
pryse is gebasseer op verdere groei
in die wêreldekonomie wat natuurlik
die vraag na energie en voedsel dryf.
Indien die teenoorgestelde plaasvind
en die wêreldekonomie beweeg in ‘n
resessie in, bestaan die moontlikheid
dat internasionale pryse met tot 30%
kan val.
Fig. 2 dui die verwagte stand van die
Suid-Afrikaanse mielievoorraad vir 2011
en 2012 aan. Weens die verminderde
aanplanting van die 2010 seisoen,
staan die eindvoorraad tans op so-
wat 1.2 miljoen ton, 49% laer as
die voorraad van 2010. Indien die
beraamde produksie van 2012 re-
aliseer, is die verwagting (met in-
agneming van verbruik) dat die
voorraad 740 000 ton hoër op 1.95
miljoen ton te staan sal kom. Hier-

die toename in voorraad sal dan, te-
same met internasionale markkragte,
ook uiteindelik afwaartse druk op die
binnelandse mielieprys plaas na onder
R 1 800/ton soos in Fig. 1 weerspieël
word.
Vooruitsigte vir sonneblom en sojabone gedurende die 2011/12 seisoen
Ongunstige marktoestande vir mielies
het veroorsaak dat produsente in die
somerreënvalgebiede aansienlik meer
sonneblom en sojabone geplant het.
Sonneblomaanplantings het met 61%
uitgebrei na 642 000 hektaar, terwyl
sojaboonaanplantings 34% meer is met
418 000 hektaar. Die hoër sonneblom-
produksie het aanleiding gegee tot
hoër voorraadsvlakke en invoere het
aansienlik afgeneem. Die herstel in
mieliepryse sal verder veroorsaak dat
sonneblomaanplantings afneem na so-
wat 574 000 hektaar in 2011/12, met
verwagte produksie wat 14% laer as
2010/11 sal wees op sowat 742 000 ton.
Vanaf Fig. 4 kan gesien word dat bin-
nelandse verbruik van sonneblomsaad
in 2011/12 sal toeneem, en tesame met
die laer produksie kan verwag word
dat voorraadsvlakke 15% laer op 118
000 ton kan afsluit. Sonneblomaanplan-
tings oor die meduimtermyn word ge-
skat tussen 570 000 en 590 000 hektaar.
Oor die langtermyn word verwag dat
binnelandse verbruik van sonneblom-
saad gaan toeneem, invoere weens
hoër produksie in die volgende dekade
gaan afneem en dat Suid-Afrika teen
2020 selfonderhoudend kan wees, sou
hierdie tendens voortgaan.
Die gemiddelde 2011 SAFEX son-
neblomprys is huidiglik sowat R 4 108/
ton (Tabel 1), en weens druk op interna-
sionale voorraadsvlakke, tesame met die
robuuste groei in die vraag na plantolies
en meel word dit huidiglik beraam op
sowat R 4 160 vir 2011/12 en kan selfs
R 5 000/ton haal oor vyf jaar as huidige
tendense voortduur (Fig. 3).

vlakke relatief stabiel te danke aan ‘n
19% toename in die binnelandse ver-
bruik van sojabone (Figuur 4). Sojaboon-
pryse volg die tendens van sonneblom
en pryse vir 2011/12 word 7% hoër as in
2010/11 geskat op sowat R 3 500/ton. Op
die mediumtermyn word beraam dat
sojaboonpryse oor vyf jaar bo R 4 000/
ton kan verhandel gebasseer op huidige
tendense.
Dit is interessant om te let dat pro-
jeksies deur die Buro vir Voedsel en
Landboubeleid (BFAP) daarop dui dat
binnelandse verbruik van sojabone
met amper 300% gaan verhoog oor die
volgende dekade, waarvan die vinnigste
groei in die persbedryf sal plaasvind.
Suid-Afrika word ook verwag om ‘n
uitvoerder van premie-draende sojabo-
ne na Asiastiese lande te word, waar
Suid-Afrikaanse sojabone veral vir die
tofu mark geskik is. Volgens BFAP,
behoort die toename in plaaslike soja-
boonaanplantings in die langtermyn
voortgesit te word en kan aanplantings
teen 2015 deur die 500 000 hektaar
merk breek.
Bul of beer-mark kan groot invloed hê
Huidiglik word ‘n positiewe prentjie
vir somergrane in Suid Afrika geskets.
Dit is belangrik om daarop te let dat
die vooruitsigte vir somergrane gebas-
seer is op die aanname dat daar eko-
nomiese groei op globale sowel as
plaaslike vlak gaan plaasvind in die
nabye toekoms.
Huidiglik flikker daar egter heelwat

gevolge vir internasionale sowel as
Suid-Afrika se plaaslike kommoditeits-
markte. Wêreldwyd word daar asem
opgehou of ‘n volgende ekonomiese
krisis afgeweer gaan word, en hang
af of dit deur politici veilig uit storm-
waters uitbestuur gaan word of gaan
die mark homself uitbalanseer met ‘n
skok?
Indien die wêreldekonomie wel op ‘n
resessie afspeel kan dit landbou-kom-
moditeitspryse negatief beïnvloed soos
onlangs in die VSA toe sojaboonpryse
tot hul laagste vlakke in byna ‘n jaar
gedaal het. Dit, tesame met ‘n daling in
mielie en koringpryse het plaasgevind
na spekulasie dat die vraag na die
spesifieke gewasse sou afneem soos
die globale ekonomie besig is om te
stagneer en die VSA se verwagte oes
hul voorraadvlakke sou opstoot. Met
hierdie negatiewe scenario in gedagte
kan Suid Afrikaanse boere egter klein
bietjie meer rustig as hul internasio-
nale eweknieë slaap, aangesien die
daling in landbou-kommoditeitspryse
tot ‘n mate in Suid-Afrika gedemp sal
wees weens ‘n verswakking in die
Rand/Dollar wisselkoers en vermind-
ering in eindvoorrade. Verdere goeie
nuus is dat China – wat ‘n groot netto
invoerder van graan en oliesade is -
se ekonomie groei, en die vraag wat
hieruit voortspruit verskaf in ‘n mate
ondersteuning aan kommoditeitspryse.
Diegene wat dus die markte met ‘n
valkoog dophou en betyds by veran-
derde omstandighede aanpas staan
die beste kans om die stormweer te
trotseer. L

I t's whale-watching season in the South African coastal town of Herma-
nus, situated about 90 minutes' drive out of Cape Town.
Since I'd never been to Hermanus or seen a real whale before, I was all for a weekend of whale spotting, but I'd mentally prepared myself for the very slim chance that I might not get to see
a whale. Yet what I took home with me that weekend was so much more than I could have dreamed possible.
We arrived in Hermanus after dark and although I knew our chalet had an ocean view, I didn't quite realise what that meant. It was only later when I closed my eyes to go to sleep and heard the hypnotic rhythm of the swells
Big, beautiful and covered in barnacles: I was on the look-out for one of the Cape coast's biggest attractions.

just outside my window, that it became clear to me.
Morning couldn't come soon enough: baby blue sky as far as the eye could see, timid waves rolling gently back and forth and there in the distance, graceful whales.
We ambled along one of the many winding pathways built along the cliff's edge, and which are a distinctive fea-ture of Hermanus. As we walked we kept our eyes on the whales in case they should suddenly disappear and we'd be left thinking they were just an illusion.
But they hung around from morning un-til night and they were dotted all over the horizon, making it difficult for us to choose where to look first, in case we missed something spectacular from one of them.
The hot weather caught us so by sur-prise that we had to head into town to buy some summer clothes. The place was abuzz with people making the most of the sunshine: some were mill-ing about licking Italian ice creams; others were tucking into full-on English breakfasts in one of the many cosy cof-fee shops scattered around.
Mostly, people were sitting on strategi-cally positioned benches – one even built in the shape of a whale's tail – watching the whales.
In the early evening we took anoth-er stroll along the cliff and ended up perched on a massive boulder jutting out into the sea as we spotted two whales enjoying an intimate moment.
Occasionally a V-shaped fountain of water would jet out from two blowholes located near the top of the whales' heads, a distinctive characteristic of southern right whales.
The whales were much closer to us now; we could actually hear the low whooshing sound as the water spurted out from within them.
The southern right whales have grown considerably in number despite being an endangered species, and we were lucky enough to be able to sit on a bench in Hermanus on a sunny day
and watch them. L

D ie ontdekking van spinetoram
is moontlik gemaak deur die
toepassing van kunsmatige neurale
netwerke (KNN) op die molekulêre
samestelling van insekdoders. Dow
wetenskaplikes het ‘n KNN gebruik
om die struktuur van spinosiene te
verstaan en gevolglik voorspellings
van verwante spinosien te maak. So-
doende kon hulle sekere eienskappe
van die insekdoder verbeter. Een van
die suksesvolle pogings was die van
spinetoram, ‘n mengsel van chemies
gemodifiseerde spinosiene J en L.
Wat beteken hierdie veranderings vir
u in u boerdery? Die eerste verbeter-
ing het te doen met lig stabiliteit (Fig
1). Spinetoram word stadig afgebreek
deur UV, wat lei tot verlengde resi-
duele werking van die produk op die
gewas wat behandel is.

Die tweede verbetering is verhoogde
effektiwiteit (doodmaakvermoë) van
spinosien J en L teen sekere insekplae.
Dit het tot gevolg dat u baie beter in-
sekdodende werking per gram aktiewe
bestanddeel verkry.

die betrokke plaag. (Dripps et al, 2008.
Spinetoram: How artificial intelligence

synthetic chemistry to produce a
new spinosyn insecticide. Plant Health
Progress: August 2008)
Ten spyte van hierdie uitstekende kom-
binasie van verbeterde residuele aksie
en verhoogde aktiwiteit teen insek-
plae, het spinetoram steeds dieselfde
lae soogdiertoksisiteit en kort leeftyd in
die omgewing waarvoor die spinosien-
groep insekdoders bekend is.
In Suid-Afrika is Delegate geregistreer
vir die beheer van Valskodlingmot,
Blaaspootjies en Bolwurm op sitrus,
Kodlingmot op Appels en Pere, Bol-
wurm en Valskodlingmot op Pruime
en Appelkose, sowel as Bolwurm, Val-
skodlingmot en Oosterse Vrugtemot op
perskes en nektaryne. In alle gevalle is
die onthoudingsperiode voor oes slegs
7 dae.

Nie alleen is dit die eerste nuwe
chemie in jare wat teen blaaspootjie
op sitrus (Fig. 3) geregistreer is nie
(Snykant – Nr 124), maar het dit ook ̀ n
lae risiko omgewingsprofiel. Daarmee
saam is dit ook uiters effektief indien
dit volgens etiketvoorskrifte gebruik
word (Fig. 4 en 5).
Vir optimale resultate beveel Dow
AgroSciences aan dat u Delegate as
‘n ligte dekbespuiting na 90% blom-
blaarval van sitrus toedien, sodra blaas-
pootjies waargeneem word. Indien die
blaaspootjie-infestasie hoog is, moet
blaaspootjiegetalle oor die eerste 4 – 5
dae deeglik gemoniteer word. Indien
die getalle nie oor die eerste 4 – 5 dae
tot onder die drempelwaardes afneem
nie kan `n tweede bespuiting 7 dae na
die eerste bespuiting oorweeg word.
Vir effektiewe weerstandsbestuur,
is dit wenslik om nie meer as twee
opeenvolgende behandelings met Del-
egate teen blaaspootjies te doen nie.
Die totale hoeveelheid toedienings van
Delegate per blok per seisoen mag nie
meer as 4 oorskry nie.
Delegate is ‘n uitstekende produk
wat sonder twyfel met groot sukses
in meeste bestaande Sitrus-spuitpro-
gramme ingesluit kan word. Dit is nie
net ‘n toonbeeld van moderne tegnolo-
gie nie, maar ook ‘n voorbeeld van Dow
se verbintenis tot volhoubare landbou.

CLIMATECHANGEFARMERS MUST ADAPT
CLIMATE
There is no doubt that climate
change associated with global
warming is widely considered to be
amongst the most serious threats to
environmental integrity and sustainable
development, affecting human well-
being and the global economy. It is
now well established that the Earth’s
climate is being adversely affected by
the build-up of greenhouse gases, in-
cluding carbon dioxide, due to anthro-
pogenic activities such as the burning
of fossil fuels.
South Africa’s climate is highly variable
and is particularly vulnerable to cli-
mate change, as farming depends to a
great extent on the quality of the rainy
season. The projected increase in the
variation of rainfall and the observed
changes in historical temperature
trends will have a serious impact on
agricultural production landscapes with
negative effects on food availability.
Brought together, impacts of climate
change will undermine food security,
especially in Africa. South Africa is
certainly not completely immune to
issues of food security.
The ultimate objective of the United
Nations Framework Convention on Cli-
mate Change (UNFCCC) is to stabilise
greenhouse gas (GHG) concentration in
the atmosphere at a level that would
prevent dangerous anthropogenic inter-
ference with the climate system. How-
ever, in meeting this objective, the
UNFCCC states that in achieving this
objective the natural environment
and human livelihoods should not be
compromised. To meet the ultimate
objectives of the Convention, the
Kyoto Protocol calls for quantified
46 - LAEVELD Summer/Somer 2011
Climate Change
reductions in developed countries'
GHG emissions for the 2008 – 2012
period. If this ultimate objective of the
Convention is to be achieved in the
long term, agreeing on a post-2012
climate change regime is crucial. To
this end, government representatives of
more than two hundred countries will
meet in Durban from 28 November to
9 December 2011, under the auspices
of the UNFCCC, for the 17th annual
Conference of the Parties (COP-17).
Climate is central in many critical ag-
ricultural decisions ranging from farm
to policy level. In addition, most of
these decisions should be made several
months in advance, before impacts of
climate effects could be realised.
In implementing an effective climate
change programme, the DAFF (De-
partment of Agriculture, Forestry &
Fisheries) will develop the Sectoral
Climate Change Adaptation and Miti-
gation plans, which will contribute to
the regulation, promotion and co-ordi-
nation of the conservation of agricul-
tural land, forest and water resources
to ensure sustainable development
and environmental integrity.
DAFF will continue to conduct climate
change research in order to inform
policy making and also to assist in
determining interventions at all levels
of governance. Associated with the
research are on-going awareness pro-
grammes which will assist farmers,
foresters and fishers to put in place
best practices which will promote
sustainable use and thereby contribute
to the green economy. L

T emperature in die omgewing
van Hoedspruit het beslis die af-
gelope twee dekades gestyg. Hiervan
is die goeie mango-oeste van die laaste
paar jaar ‘n sprekende voorbeeld.
So sê prof. Stefan Grab van die skool
vir geografie, argeologie en omgewing-
studie aan die Universiteit van die Wit-
watersrand.
Grab is lid van ‘n navorsingspan wat ‘n
projek met die South African environ-
mental Observation Networks (Saeon)
onderneem om te kyk na die uitwerk-
ing van klimaatsveranderig op land-
bougewasse en die moontlike maniere
om daarby aan te pas.
Hy sê die styging in die temperature by
Hoedspruit het beslis die mango-oeste
bevoordeel. “As die temperature egter
aanhou styg, kan die oeste dalk later
nadelig geraak word en sal dié boere
na ander gewasse moet oorskakel.”
Hy waarsku mense om hulle nie te laat
mislei deur die term ‘aardverhitting’ nie
omdat klimaatsverandering wat daar-
mee saamgaan nié net ‘n aanduiding is
van temperature wat styg nie.
“Ons ervaar interessante tye met intense
klimaatskommelings. Dit beteken ons er-
vaar uiterstes. Uiterste koue, uiterste hitte.”
Volgens ‘n verklaring deur Saeon het
wetenskaplikes oor die wêreld heen

reeds konsensus bereik oor die feit dat
die impak van klimaatsverandering nie
oral op aarde dieselfde gaan wees nie.
Hulle is dit ook eens dat Afrika die
ergste gaan ly, deurdat dié mense
hulle in ‘n ontwikkellende wêreld be-
vind waar die vermoë ontbreek om by
die veranderde klimaat aan te pas.
Dit is noodsaaklik dat boere hulself
voorberei op temperature wat vermoe-
delik in die volgende dekades met tot
4˚C kan styg. L

Water RetentionIf we do not drink enough water, our bodies start to retain water to compen-sate for this. To sort out water retention, we should drink more water, not less. The less water you drink, the more the body sees its survival as threatened and conserves every drop. Water starts being stored outside the cells and this causes swelling of the feet, legs and hands. The body will get rid of the excess liquid only once the necessary water levels have been replenished.
Body TemperatureWater helps to regulate the tempera-ture of our bodies through respiration and perspiration. The complex mecha-nism that controls body temperature works by means of water and is con-trolled by the central nervous system, which controls the internal temperature.
BreathingIt sounds strange, but we need water in order to breathe. In order to take in oxygen and eliminate carbon dioxide, our lungs must be moistened by water.
We lose between half a litre and a litre of water every day just by breathing.
BrainBrain tissue consists of 85% water, and with dehydration, the level of energy pro-duction in the brain decreases. Depres-sion and chronic fatigue syndrome are often the result of dehydration. Migraine may be an indicator of critical body temperature. Dehydration causes an in-crease in the internal temperature and plays a major role in leading to migraine.
PregnancyWater helps to convey the nutrients through the baby's blood. Water also helps to prevent bladder and urinary tract infections, constipation and piles in the mother. Correct hydration is es-sential for good milk production and for constant replacement of leaks of am-niotic fluid. Dehydration could induce contractions and premature birth. L

We know water is good for us, but with cold fizzy drinks, juice, coffee, tea, energy drinks, and other drinks so readily available, it’s hard to make the decision to choose water. Here is why it is important to drink water:
