INSECT CONTROLThe management of insect pests on potatoes continues to rely on synthetic insecticides but their continued usefulness can only beinsured by the concurrent use of cultural and alternative control methods.

ScoutingMonitor each field once or twice a week to identify the insect pests present and determine the relative abundance of their differentlife stages. Note the growth stage of the crop. Keep in mind that the previous crop, cropping practices and the type of vegetationsurrounding the field affect the presence and the development of the insects. Information on the changes in the abundance ofinsect pests in your region can be obtained from a variety of pest forecasting and monitoring services offered by governmentextension specialists and private consultants.

Use all the information gathered to develop an insect control program for the season or to respond to a specific pest outbreak.

Alternative Control MethodsA number of non-insecticidal control methods are now available. These methods are environmentally friendly and help prolong theeffective life of insecticides if they are used consistently, year after year. These methods are most effective against the Coloradopotato beetle but many will help reduce the abundance of other insects.

Field rotation. Rotate fields frequently and isolate fields whenever possible. This will delay field colonization by overwintered adultsand reduces their abundance in the crop. Increasing the distance between last year’s potato field and this year’s potato field willincrease the level of beetle control.

Plastic-lined trenches. Install trenches around potato fields adjacent to Colorado potato beetle overwintering sites or field plantedto potatoes the previous year. On the average, trenches reduce the abundance of overwintered adult beetles on the crop by 50%. This will also reduce the number of egg masses in the potato field.

Propane burner. Very effective at reducing the abundance of overwintered adult Colorado potato beetles on short plants up to 4" inheight. Also reduces the viability of egg masses. More than one pass per season may reduce yield.

Because of Colorado Potato Beetle resistance to insecticides and to prevent the development of resistance in other pests, AVOID REPEAT APPLICATIONS OF INSECTICIDES FROM THE SAME CHEMICAL GROUP.

Insecticidal ControlInsecticide resistance is present in many populations of Colorado potato beetles in the Atlantic region. It is recommended that afewsimple steps be followed to manage the problem with the Colorado potato beetle and prevent the development of insecticideresistance.1. Reduce the number of insecticide applications by using alternative control methods.2. Apply an insecticide only if the abundance of an insect pest has reached a level where it can cause an economic yield

loss.3. Rotate to an insecticide of a different chemical class after each application of a particular insecticide. In the case of the

Colorado potato beetle, use an insecticide resistance test kit if one is available in your region, to help determine if yourbeetles are resistant to a particular insecticide.

4. Use the right nozzles on a recently calibrated sprayer to insure that the insecticide is applied to the target pest on the cropwith minimal drift to the environment. Consider banding rather than treating the whole area.

5. Apply only at the recommended rate for the pest.6. All insecticides listed in this guide will control some potato insect pests, however, differences in their respective modes of

action, persistence, sensitivity to temperature and pest specificacy must be considered when choosing a chemical.

NOTES ON INSECTICIDESMany of the insecticides used on potatoes are highly poisonous to man, animals, fish and beneficial insects. Poisoning of theapplicator can occur by swallowing, inhaling or by skin contact. FOLLOW ALL PRECAUTIONS STATED ON THE PRODUCT LABEL.It is against the law not to comply with the label instructions of a pesticide under the Pest Control Products Act of Canada.Contamination of fisheries waters by pesticides is also against the law under the Fisheries Act of Canada.

Carbamates

Non systemic carbamates generally remain effective for 7 -10 days.

Carbaryl has low toxicity to man and animals but is highlytoxic to bees. It is effective against beetles for 3-4 days underfavourable conditions (the XLR formulation may be wash-offresistant for as much as 7 - 10 days). It does not controlaphids. Repeated applications usually cause an increase inaphid populations, since it kills aphid predators.

Carbofuran is highly toxic to humans. Foliar applicationsare effective against beetles through contact action. Carbofuran does not control aphids. Applications of Furadanusually result in an increase in aphid populations, since itkills aphid predators.

Methomyl has low toxicity to man and animalsbut is highly toxic to bees. Foliar applications are effectiveagainst aphids and flea beetles through contact and somesystemic action. Effective insect control lasts less than 7days.

Oxamyl has moderate toxicity to humans. It is effectiveagainst the beetles and the aphids through contact andsystemic action.

Pirimicarb has low toxicity to humans. It is very effectiveany time against aphids, acting through contact and vapouraction.

Chlorinated hydrocarbons

Endosulfan is moderately toxic to humans. It is effectiveagainst beetles and the buckthorn aphid. Low temperatures

decrease its effectiveness, especially against the buckthornaphid.

Methoxychlor has low toxicity to man and animals but ishighly toxic to fish and bees. It is effective against aphids,Colorado potato beetles and potato flea beetles throughcontact action.

Chloronicotinyls

Nicotinyls affect the nervous system of insects by blocking aspecific type of receptor on the post-synapse.

Acetamiprid is effective against the Colorado potato beetleand aphids. Imidacloprid is effective against the Coloradopotato beetle, the flea beetle and aphids. Both products havelow toxicity to humans and animals but when used as a foliarspray are highly toxic to bees.

Naturalyte

Unique mode of action associated with insect nervoussystem and acts through contact and ingestion. It is notsystemic in the plant.

Spinosad is effective against Colorado Potato Beetle andEuropean Corn Borer. It has very low toxicity to humans,animals and beneficial insects but highly toxic to bees. Maximum application per season is 249 ml/ha. TargetColorado Potato Beetle at egg hatch and small larval stages.

Organophosphates

Non-systemic organophosphates remain effective for 7-14days.

Chlorpyrifos has low toxicity to humans. It works throughcontact, ingestion and vapour action against the beetles. Itdoes not control aphids.

Diazinon has low toxicity to man and animals but is highlytoxic to bees. It works through contact, systemic andingestion actionagainst aphids, Colorado potato beetles, and potato fleabeetles.Dimethoate has low toxicity to humans. It is effectiveagainst the potato and the buckthorn aphids by contact andsystemic action.

Malathion has low toxicity to man and animals but is highlytoxic to bees. It is registered for use against aphids and,most formulations, the Colorado potato beetle.

Methamidophos is highly toxic to humans. It is effectiveagainst both species of beetles and all three species ofaphids by contact and local systemic action. It will controllarge populations of aphids late in the season. It provides aquick, initial knockdown as well as residual control.

Naled is moderately toxic to humans. It is a fast actinginsecticide that gives good control of the beetle. Do not applyabove 32°C.

Phorate is highly toxic to humans. It is effective against allpests. It does not persist long enough to control the secondpeak of flea beetles and its control of aphids is variable.

Phosmet has low toxicity to humans. It is a contact andstomach poison that is effective against the beetles.

Pyridine Azomethines

Pymethrozine mode of action is of a neural inhibition offeeding behavior.

Pymetrozine is very selective for activity against the GreenPeach, Potato, Foxglove and Buckthorn aphid. Aphids stopfeeding after exposure by contact or ingestion. Aphids do notfeed again and subsequently die after several days due tostarvation or dessication. A reduced risk product for humansand animals.Thorough spray coverage of plant foliage is essential foroptimum control. The use of an adjuvant such as Agrol 90,Agsurf, LI 700 or Sylgard 309 is recommended to improvethe performance of Fulfill under drought stress conditions.

Synthetic Pyrethroids

In contrast to carbamates and organophosphates the toxicityof pyrethroids decreases as temperature rises. Wheneverpossible synthetic pyrethroids should be applied at

temperatures below 24°C. They are generally toxic to beesand other beneficial insects but most are of low mammaliantoxicity. These insecticides are extremely toxic to fish, shellfishand aquatic organisms which are food for fish and waterfowl. Careless use can seriously harm sport and commercialfisheries and wildlife.

Although pyrethroids are generally poor potato aphicides, theymay reduce probing by colonizing aphids which may protect theplants from infestation and virus spread as long as the residualdose is sufficient, even if it is no longer lethal. Being virtuallyinsoluble in water, they offer excellent resistance to leaching outduring rain. They should not be used on muck soils.

Allow a minimum of 24 hours before evaluating the efficacy of apyrethroid spray to permit enough time for the insects to return tothe plant and feed some more after the knockdown effect.

Cypermethrin is effective against the beetles by contact andstomach action.

Deltamethrin is effective against the beetles as a contact andstomach poison. May be effective against the common potatoaphid and the buckthorn aphid at higher rates.

Cyhalothrin-lambda is effective against Colorado potato beetlesby contact and stomach action.

Permethrin is effective against the beetles. Thorough coverageof plants is important and the higher rate is required for heavyinfestations. It is a contact and stomach poison.

Bacteria

Some varieties of the bacterium Bacillus thuringiensis are activeagainst the larvae of the Colorado potato beetle. For optimumresults, apply early in the season against small actively feedinglarvae. Repeat the application twice at intervals of 5-7 days orafter a heavy rainfall. The bacteria are not fast acting. Larvaldeath occurs only 1 - 5 days later but the larvae stop feedingafter eating foliage sprayed with the bacteria. These productsare not very effective against large larvae and will not kill adultsand other insect species.Bacillus thuringiensis (Novodor) is effective against theColorado potato beetle larvae by stomach action. The higherrate is required for heavy infestations.

Botanicals

Rotenone is prepared as ground up roots or extracts of the rootsof plants from the genera Derris and Lonchocarpus. It is highlytoxic to fish. It has moderate toxicity to mammals, except highlytoxic to pigs. It is moderately effective against some species ofaphids. Breaks down rapidly when exposed to light and air, thusgood for use on crops close to harvest.

All herbicides are known by a chemical name. Agricultural chemical companies use trade names for their products, but, by law, theymust include on the label the accepted chemical name for the herbicide and the actual amount of that herbicide in the product.Supply companies sell products with different concentrations for the same herbicide and over the years some have changed theconcentration of active herbicide in a product. Suggested rates in these notes specify the amount of herbicide product required perhectare.

CLETHODIM sold as SELECT contains 240 g/L of clethodim. Itshould be used at all times in a tank-mix with the adjuvantAMIGO. Clethodim is a systemic postemergence herbicide withuptake primarily through the leaves. Potatoes are tolerant toclethodim at all growth stages. Thorough coverage of the leaffoliage is necessary for consistent grass control. Do not apply ifrainfall is expected within 1 hour of application.The time forcomplete control is normally 7 to 21 days depending ongrowing conditions and crop competition. Apply Select whenthe annual grasses are in the 2 to 5 leaf stage and whenquackgrass is in the 2 to 5 leaf stage.

DICLOFOP-METHYL, sold as Hoe Grass contains 284 gdiclofop-methyl per liter of Hoe Grass. Diclofop-methyl isapplied post-emergence to the potatoes for control of annualgrasses in the 1 to 4 leaf stage. It will effectively controlbarnyard grass, green and yellow foxtail, wild oats, oldwitchgrass, fall panicum and volunteer corn. Quackgrass willnot be controlled. Apply in 100 to 300 liters of water per hectare.Do not apply if rain is expected within one hour afterapplication. Tank mixture of diclofop-methyl with otherchemicals must not be used. As diclofop-methyl controls onlygrass weeds, it is important to control broadleaf weeds byusing an appropriate pre-emergence herbicide.

EPTC, sold as Eptam 8E, contains 800 g emulsifiableconcentrate (EC) of EPTC per litre. It is applied under lowpressure 200 kPa in 110-340 litres of water per hectare. Alsoavailable in granular formulations, it is used for potatoes as apre-planting, pre-emergence or post-emergence treatment formany weeds, including annual grasses, quackgrass andnutsedge. A few broadleaf weeds, such as wild radish and wildmustard are not controlled. For control of annual grasses applyand incorporate EPTC either pre-planting or at lay-by. For control of dense stands of nutsedge and quackgrass apply andincorporate EPTC pre-planting. The underground quackgrassrhizomes must be cut up thoroughly so that four or less nodesremain on a stem. This is best done with discs set to cut 15 to20 cm deep.

EPTC must be incorporated into the soil immediately to preventloss of the herbicide. Once trapped into the soil, the vapourwhich forms when EPTC comes into contact with moisture actsto destroy germinating weed seeds and quackgrass rhizomesif the rhizomes are cut into short lengthsof 7.5 cm or less. The soil must be in good tilth and have a drysurface. EPTC sprayed on wet soils vaporizes quickly into theair and is lost. It is less active in cold soils than in warm soils. Itis difficult to incorporate into stoney soil. Whenever possible,application and incorporation should be done in the sameoperation

EPTC is incorporated using power driven cultivation equipmentset to cut to a depth of 5 to 8 cm, or tandem discs set to cut to adepth of 10 to 15 cm, operated at 6.4 to 9.7 kilometres per hour,or a Danish type cultivator, with tines set on 15 to 20 cmcenters, set 10 cm deep, operated at 10 to 13 km/hr. andfollowed by a spike tooth harrow or some other leveling devicewhich extends beyond the ends of the discs or cultivator.

An overspray with a pre-emergence or post-emergenceherbicide to control germinating annual broadleaf weeds isusually required to control some weeds tolerant to EPTC.

FENOXAPROP ETHYL, sold as Excel Super contains 80.5 g offenoxaprop-p-ethyl per litre of Excel Super.

Fenoxaprop-p-ethyl is applied post-emergence to the potatoesfor control of annual grasses in the 1 to 6 leaf stage. It willcontrol green and yellow foxtail, barnyard grass, crabgrass, oldwitch grass, fall panicum and volunteer corn. Fenoxaprop-p-ethyl does not control broadleaf weeds, sedges, quackgrass orother perennial grasses. Second flushes of annual grasseswill not be controlled since fenoxaprop-p-ethyl is not residual.

Apply Excel Super in at least 100 litres of water per hectare.Thorough coverage of the foliage is essential for effective grasscontrol. Application through flat fan nozzles at a 45 degreeangle forward will result in the best spray coverage. Do notapply if rain is expected within 1 hour of application.

As fenoxaprop-p-ethyl controls only annual grass weeds, it isimportant to control broadleaf weeds with another herbicide. Atime interval of four days before or after fenaxaprop-p-ethylapplication is required before any other pesticide is applied.

FLUAZIFOP-P-BUTYL, sold as Venture L contains 125 gfluazifop-p-butyl per litre. It is applied post-emergence to thepotatoes and weeds and will give control of many annualgrasses and also quackgrass. It does not control broadleafweeds or sedges such as nutsedge. Growth of grasses stopssoon after application but destruction of the whole plant maytake several weeks. For annual grass control, apply when theannual grasses have 2-5 leaves. For quackgrass control, applywhen the quackgrass has 3 to 5 leaves on each shoot. Do notapply if rainfall is expected within 2 hours of application.

GLUFOSINATE AMMONIUM is the active chemical in IGNITE.DO NOT USE ON POTATOES GROWN FOR SEED. Applyglufosinate ammonium in at least 110 litres of water perhectare. Application of the spray at a 45° angle forward willresult in better coverage. Leave a 15 M buffer between edge offield and environmentally sensitive areas. DO NOT spray whenwinds exceed 16 km/hr. when using open boom sprayers.Apply IGNITE at no later than ground crack. Only emergedweeds will be controlled with IGNITE. For residual control ofannual weeds, IGNITE may be tank mixed with SENCOR 500For LEXONE DF. Do not apply if rainfall is expected within 4hours.

GLYPHOSATE, sold as Roundup containing 356 g ofglyphosate per litre as isopropylamine salt, or GLYFOScontaining 360 gram of glyphosate/liter as isoprpolamine salt,or TOUCHDOWN iQ containing 330 g of glyphosate per litre astrimethylsulfonium salt, for perennial weed control prior toplanting potatoes. Apply glyphosate in the spring or fall forquack (couch) grass control. The quackgrass must be at least20 cm in height (3 to 4 leaf stage). Tillage prior to applicationwill reduce control of quackgrass.

Weed control with glyphosate is reduced if dirty water is usedfor application. Where tillage is desired, delay for 5 to 7 daysafter application. Glyphosate has no soil activity. Therefore, itwill not injure crops planted in the treated area. Roundup, whenused after weed emergence but before ground crack andpotato emergence will control emerged weeds. Emergedpotato plants will be injured and reduced yield may result.

LINURON* sold as Lorox L or Linuron 480 FL containing 480 gLinuron per litre or Linuron 400 FL with 400 g/L linuron, orLorox DF containing 50% linuron. Apply linuron before potatosprouts emerge, never on the sprouts.

Abnormally heavy rainfall following application may cause cropinjury. However, moisture is needed for good weed controlaction. Potato sets should be 5 cm below the treated soil.

The high rate usually controls annual grasses such asbarnyard grass. Do not use on sand or coarse textured soilslow in organic matter. Use the higher rate on clay.

Linuron formulated as soluble granular (DF) requires constantagitation to keep it in suspension.

METRIBUZIN sold as Sencor Solupak 75DF, and Sencor DF(dry flowable) 75% metribuzin, Sencor 480F, a liquid, contains480 g/L. Metribuzin is used pre-emergence to potatoes. Thehigher rate is usually required to control annual grasses anddense weed infestations. Also, the higher rate will retard thegrowth of quackgrass (use the lower rate for broadleaf weedcontrol only). Moisture is needed shortly after a pre-emergenceapplication for better weed control.

Do not use on Belleisle, Tobique, Sante or Tolaas cultivars.Use only pre-emergence on Shepody cultivars. Do not use onmuck soil. Fall-seeded cover crops and certain vegetablessuch as cole crops, seeded the following spring are likely to beinjured. Avoid overlaps that will increase dosages above therecommended. Read the manufacturer’s label.

PRE-EMERGENCE APPLICATION (PLANTING TO GROUNDCRACK) OF METRIBUZIN IS PREFERRED. However, where itis not possible to spray before crop emergence, metribuzin canbe applied early post-emergence before weeds are 4 cm highand before first emerged potato tops are 7.5 cm high. Thistreatment may cause temporary yellowing and/or leaf burn,especially when the crop is under the stress of poor growingconditions such as cool, wet, cloudy weather. Under AtlanticCanada conditions, a few early post-emergence applicationshave occasionally reduced vine growth sufficiently to retardbulking and possibly to reduce yield. However, under thesesituations, the use of metribuzin early post-emergence topotatoes could be better than abandoning the crop to weedssuch as barnyard grass which are difficult to control bycultivation.

Some of the limitations on early post-emergence applicationsare as follows:

a) Do not use when plants are under stress, such as cool,wet, cloudy weather or very dry soil conditions.

b) If insufficient metribuzin was used pre-emergence, it maybe necessary to apply an additional early post-emergencetreatment to control annual grass. In one season, do notapply more than a total of 1.1 kg active metribuzin perhectare.

c) Weed control with early post-emergence application is most effective when spray is applied before weeds are 4cm high.

d) Do not apply metribuzin early post-emergence on Shepody, Tobique, Belleisle, Sante, Tolaas, red- skinned varieties or potatoes grown for early market.

e) Superior and Norchip are mid-season varieties which appear to be sensitive to metribuzin applied post-emergence.

PARAQUAT, sold as Gramoxone containing 200 g paraquatper litre kills weeds on contact with the foliage. Apply in 280 to560 litres of water per hectare to emerged weeds includingquackgrass. It can be used postemergence on potatoes upuntil the stems are 5 cm high (one week after ground crack),except Russet Burbank. Do not apply postemergence topotatoes in the evening, or on cloudy days, or when the plantsare under moisture shortage. Temporary chlorosis (loss of leafcolour) of potato leaves will occur.

Application of paraquat for emergency control of quackgrassand emerged annual grass may be made when shoots are upto 10 cm high (not to Russet Burbank) but potato leaf chlorosismay be more severe and yield could be reduced. Lateapplication should only be considered when quackgrass orannual grasses threaten the crop.

Use clear water for applying paraquat as it is deactivated byclay or organic particles.

Paraquat is inactivated on contact with the soil so there is noresidual action in the soil. If new weed growth appears, it will

be necessary to cultivate or use a post-emergence herbicide.Usually, the lay-by cultivation (hilling) will be sufficient. Forresidual control of annual broadleaf weeds and annualgrasses, tank mix paraquat and metribuzin or tank mixparaquat and linuron or monolinuron. Use the lower rate oflinuron, or monolinuron on lighter soils and the higher rate onheavier soils with high organic matter. Apply the tank mix beforethe potatoes emerge.

RIMSULFURON sold as PRISM containing 25 % rimsulfuron, isa dry flowable formulation in water soluble bags. It is applied ina minimum of 100 l/ha of water and must be used within 24hours as the herbicide will degrade in acidic or highly alkalinewater. It must be applied with a non-ionic surfactant asrecommended on the label. Mix Prism with at least one quarterof the water first and add the surfactant after the herbicide isthoroughly mixed. Prism is applied as a post-emergencetreatment to control annual grasses in the 1 to 6 leaf stage andquackgrass in the 3 to 6 leaf stage. Control of some broad-leafweeds is also obtained. Do not apply if rainfall expected within2 hours of application.

SETHOXYDIM, sold as Poast Ultra contains 450 g ofsethoxydim per litre. Sethoxydim is a postemergence, contactand systemic herbicide for control of certain grasses anduptake is primarily through leaves. Thorough coverage of thefoliage is necessary for consistent grass control. Completeannual grass destruction takes 7 to 21 days depending ongrowing conditions and crop competition. Destruction ofquackgrass may take 6 to 8 weeks.

Application is made at the 1 to 6 leaf stage of annual grassesand at the 3 leaf stage of quackgrass. A cultivation no soonerthan 7 days after application of sethoxydim will improve grass

control. Best results are obtained in water volumes of 50 to 200litres per hectare. Do not use flood jet or hollow cone nozzleswith this herbicide as level of grass control will be reduced.See product label of Poast Ultra for information on rate ofapplication and mixes with surfactants Merge and Assist.Surfactants are required to be used with Poast Ultra. Thisherbicide does not control broadleaf weeds. Use anappropriate pre-emergence herbicide to control broadleafweeds. Do not apply if rainfall isExpected within 1 hour of application.

S-METOLACHLOR , sold as Dual II Magnum containing 915 g/Lemulsified concentrate (EC). It controls large and smoothcrabgrass, witch grass, barnyard grass, fall panicum, greenand yellow foxtail, yellow nutsedge, American nightshade andeastern black nightshade. For control of yellow nutsedge applypre-plant incorporated (ppi) (see label) or for annual grasseseither ppi or pre-emergence. Use the higher rate whereverannual grasses or yellow nutsedge predominates or densitiesof weeds are expected to be high. Do not apply to potatoes atground crack or if potatoes have emerged. Rainfall within 10hours is required for maximum activity of the pre-emergenceapplication. Residual activity will normally be retained for 10 -14 weeks. Winter cereals may be planted 4 - 5 months after s-metolachlor application. See the product label for registeredtank mix combinations. Do not use s-metolachlor on mucksoils or coarse textured soils low in organic matter. Do not useon the variety Superior.

DISINFECTIONCleaning and disinfection of storages and potato handling equipment each year are essential elements of a potato diseasemanagement program to eliminate carryover of disease-causing bacterium. Warehouse and equipment disinfection programs areprimarily to control bacterial ring rot (BRR) of potatoes, but can also reduce the potential for soft rot, silver scurf, and fusariumproblems. An effective disinfection program is a three-step process that includes:

1 Removal of all loose debris, dirt, and trash from equipment and the warehouse.

2. A thorough cleaning of all surfaces! Cleaning is best accomplished using water, a pressure washer, and a detergent. Thedetergent helps to prepare a surface for subsequent disinfection.

3. A registered disinfectant, applied after cleaning and in a way that ensures the surface remains wet for a minimum of tenminutes.

Disinfection of set-cutters and planters between seed lots is important in reducing the potential for pathogen transfer betweendifferent seed lots. Sponge rollers on set-cutters should be removed, cleaned then soaked in a container of disinfectant. Used orborrowed equipment should be cleaned and disinfected before it arrives on the farm and before it is returned.

Transport trucks arriving on farms for loads of potatoes must be disinfected, before arrival on the farm. The possibility exists forsuch vehicles to carry potato debris from one location to another with the risk of disease spread.

NOTES ON TOPKILLERSDIQUAT is the active chemical in Reglone 240. Applications

should be made after growth has passed its peak, ratherthan when plants are growing actively.

Apply Diquat in 560-1100 litres of water per hectare (LabelDirection). Do not apply Diquat during drought conditions,wait for at least three days after the soil has been thoroughlymoistened by rain or irrigation. Use clear water with diquatas it is deactivated by clay or organic particles.

Laboratory tests show that diquat (Reglone 240) is stableand compatible with the following fungicides: Dithane DG,Polygram DF, Bravo Flowable, Manzate 200DF and coppersulphate. Do not use any wetters (Agral 90) or stickers inEastern Canada.

GLUFOSINATE AMMONIUM is the active chemical in IGNITE.DO NOT USE ON POTATOES GROWN FOR SEED. Applyglufosinate ammonium in at least 110 litres of water perhectare. When canopy is dense or weed growth is heavy, use170 to 220 litres of water per hectare. Do not harvest thetreated crop within 9 days of application. Uniform, thoroughspray coverage is important to consistent crop desiccation.Better desiccation will be achieved if the potato vines arepast peak growth, rather than actively growing. Do not applyto potato plants that have not passed the peak growth period

and begun natural senescence. Do not apply to potato plantsduring overly wet conditions that favor the development ofstorage rot (heavy rainfall/saturated soils). Do not tank mixIgnite with ammonium sulfate or any other adjuvants notlisted on the label.

ENDOTHALL is the active ingredient in DES-I-CATE. For lightvine growth apply 17 - 22 L/ha of DES-I-CATE using thehigher rate in cloudy, cool weather. For heavy vine growth usethe full rate of 22 L/ha and spray to thoroughly wet the lowerstems. For best results, use a sprayer pressure of 700-1050kPa using 500 - 800 L of water /ha. Applications should bemade 10-14 days prior to harvest. Add DES-ICATE to thespray tank after adding water to reduce foaming.

In situations involving very heavy vine growth, doublespraying, first up and then down the field on the same day,applying 11 L/ha per application, will maximize coverage andtop desiccation. No wetting agent or emulsifier is neededwith DES-I-CATE. Under conditions favourable for rapid vinegrowth, such as low soil moisture or high temperature, donot use the high rate as stem end discolouration may occur.

• Never use sprout inhibitors in a seed storage.• Never store treated potatoes in a seed storage.

• Never use treated potatoes for seed.

SPROUT INHIBITORSSprout inhibitors provide a rather inexpensive means of keeping potatoes in good condition for the late fresh and processingmarkets. Sprouts increase water loss from tubers and reduce the volume of saleable potatoes. Sprouting may cause color loss inprocessing potatoes.

When sprout inhibitors are used as directed, tuber residues are below tolerance levels and there are no harmful effects onhumans.

PRODUCT METHOD OF APPLICATION COMMENTS

POST HARVEST FUNGICIDESThese fungicides are effective only when the TOTAL SURFACE of each tuber is covered and recommended rates are used.

Dithane F-45Dithane F-45 is registered for the control of Fusarium dry rot on SEED POTATOES. Apply 1.58 litres of Dithane F-45 in 4-8 litres ofwater post harvest per 1000 kg of seed potatoes. Apply as a spray on a conveyer belt prior to storage.

Mertect SCApply Mertect (thiabendazole) as a mist spray on WHOLE potatoes going into storage to control the fungal diseases caused byFusarium , Phoma, Rhizoctonia, and the diseases Silver Scurf and Skin Spot. Add 7.5 litres of Mertect to 170 litres of water. Applythis suspension at the rate of 2 litres per 1000 kg of potatoes. This treatment is effective only when the recommended rate is used.Improper use can result in development of resistant strains of fungal pathogens of potatoes.

Mertect SC can also be applied at the same application rate when potatoes are being moved, as fungal pathogens are present ongrading equipment and mechanical injuries will create an entry point for fungal diseases.

CAUTION: DO NOT combine Mertect SC with chlorinated compounds. DO NOT use after sprout initiation. Some resistant strains ofFusarium Rot and Silver Scurf pathogens are now present in the region, reinforcing the need to use recommended rates andapplication methods.

Oxidate (Biosafe )Oxidate is used for the control of Fusarium Tuber Rot, Silver Scurf and Bacterial Soft Rot. Applied to potatoes going into storage, mix100 ml of oxidate per 10 L of water. Use 4.15 - 8.3 L of water per tonne of potatoes. Spray diluted solution on tuber to runoff toachieve full and even coverage.Additional applications to potatoes in storage can be made daily, as a direct injection into the humidification water.

CAUTION: DO NOT use after a sprout inhibitor (liquid or fog formulation) has been applied to the potatoes.

THINK SAFETY

GUIDELINES FOR CHEMICAL PESTICIDE SAFETY

Treat all pesticides (insecticides, herbicides, fungicides, etc.) aspoisonous substances and handle them with great caution. Theycan kill.

1. Read each pesticide label carefully and follow the instructions. The instructions on a pesticide label serve tosafeguard the health of the user as well as to ensure thepesticide is employed as efficiently and economically aspossible. When in doubt, read the label.

2 Except where product labels read otherwise, nitrile gloves arerecommended. Always refer to product label.

3. Always wear the recommended protective clothing and safetyequipment. Pesticides may enter the user’s body throughthe skin, the mouth or by inhalation. The protective equipmentworn by the conscientious pesticide applier includes arespirator orgas mask, a wide-brimmed hat, goggles, a shirtwith long sleeves over gloves, overalls with rubber bandsaround the cuff, and neoprene or rubber boots. Becausefumigants are readily absorbed by neoprene, be sure to followlabel instructions. Don’t follow someone else’s bad example.Wear the required safety equipment. It’s for your own good.

4. Open, pour, weigh and mix pesticides in a safe manner andaccording to label instructions. Use the proper tools to open acontainer. Stand upwind of all opening, pouring and mixingoperations, and in a well-ventilated area. Avoid splashing andspilling.

5. Learn to recognize the typical signs of poisoning and thecorrect first aid procedures. Keep a first aid kit handy. Somesymptoms of acute poisoning are nausea, diarrhea, loss ofmuscle coordination, stomach cramps, mental confusion, etc.

6. If you feel ill during pesticide application, stop work and seekmedical attention at once. Do not carry on because of the workschedule. Always save the pesticide container or the label toassist the medical aid person. Do not permit any personincluding yourself, to work alone when handling or applyingpesticides.

7. Never use your mouth to siphon liquid materials or to blow outa clogged spray nozzle.

8. Keep people and animals away from contaminatedequipment and areas until decontamination procedures arecomplete.

9. Be sure a good supply of lime, sawdust, or other absorbent is available on site to soak up a spilled pesticide.

10. Do not permit anyone unfamiliar with chemical safetypractices to carry out cleaning or maintenance procedures.Appropriate protective equipment is necessary for cleaningand maintenance personnel.

11. Always dispose of irreparable faulty protective equipment andcontaminated clothing.
