Biological Controls Interview with Richard Ward, and Industry Leader

Editor: Over the past ten years, whatwould you say are the greatest chang-es that have occurred in the use ofbiocontrols in landscape management?

I would say that the Landscape industry

has become very much more aware ofthe benets of biological control. Thisis because of two main reasons. Firstly,that companies dealing in biologicalcontrol have been expanding theirmarkets from the traditional vegetablemarket into the ornamental and land-scaping industries. Second is the factthat many of the traditional chemicalsused in the landscape industry arenow not available, or on the list to bephased out.

Over the coming ten years, whatwould you expect to be the most sig

-

nicant developments in biocontrolsin landscape management?

I think the industry will continue to ex-pand its use of biological control, espe-cially in the areas of soil borne insectsand grubs. Bio-control companies arealso looking at this side of the industryas one with great potential, so workingtogether, I think that both industries canand will benet from the developmentof new products for this sector. Interior-scapes is also a market that is growingrapidly as the use of chemicals is nowforbidden in most of these areas thatmay be visited by the public.

Landscape professionals are generallymore aware of arthropod biologicalcontrols than others. What other vectorsof biological control are having signi-cant impact and how are they used?

What do you see on the horizon in theway of new biocontrol products/vec-tors? Nematodes are being used moreand more in the landscape and golngindustry for the control of soil borne in-sects. There are a number of nematodeson the market now that have had goodsuccess in this area. Education is veryimportant in that it is crucial that theseproducts be applied correctly if theyare to work and produce the resultsexpected. Detailed instructions arenormally given to new users and mostbio-control companies have technicalstaff to help with any questions thatcustomers may have.

Some concern has arisen in certaincases among landscape professionals andcooperative extensions regarding avail-ability of certain biocontrol products.How is the biocontrol industry address-ing this concern?

As you know, we are dealing with liveproducts in this industry and as such allhave a specied shelf life or use by datefor best results. As we develop this side ofthe industry more, we as producers willget a better feel for the market, its poten-tial usage and time frame. I think one ofthe reasons some companies have experi-enced shortfalls in supply is because thisis still a developing side of the industryand none of us (producers or consumers)at this point have any idea what the yearlyusage will be. Hence I refer back to thefact that we are dealing with live product,which cant be put on a shelf and inven-toried for months so as to be assured ofhaving product when demand suddenlyincreases. The other problem we face isthe change in demand from one year tothe next. For example, white grubs may bea huge problem this year and a very minorone next year. It is very difcult to plan forthis when producing live product.

Another concern is quality control.How do you feel the creation of aninspection/quality assurance programwould affect producers and consumers ofbiocontrol products?

This is a subject of great concern to our in-dustry and most of the producers are pain-fully aware of the costs and ramicationsif product does not arrive at the consumerin good condition. Our producer associa-

tion, the ANBP (Association of NaturalBio-Control Producers) works veryclosely with ASTM and IOBC to de-velop standards for use by producers.We also work closely with independentresearchers to develop testing methods

that are quick, easy and accurate forthe consumer to do upon receipt of theproduct/s they ordered. There are someproducts that are not good shippersas we refer to them in the industry, butit is up to the individual companiesselling these products to advise theircustomers of the possibilities of dam-age or cannibalism during shipment.For the most part, I think most compa-nies are doing this well and most willover pack these products to compen-sate for this possibility.

How do you think the use of bio-logical controls has improved thelandscape professions as well as theexperience of the clientele?

Bio-control has improved the veg-etable, ornamental and landscapeindustry by drastically reducing thedependence on harmful chemicals.This is especially true in the landscapeindustry as many soil insecticideswere being used that would eventuallynd their way into our underground

water supply or our streams, rivers andlakes. The use of biological controlhas severely reduced the use of thesechemicals in the landscape industryand in so doing, has eased the impactof harsh chemicals on our environmentin a small, but still signicant way. Thereduction/de-registration of chemicaltreatments has also made landscape,city, and PCA personnel more vigilantto possible insect problems and hencethey can be treated biologically beforethey become too large a problem.

IN THE NEWS: BLOWERS LOSE Reprinted from Landscape Online WeeklyTree-lled Palo Alto, Calif. has banned gas-powered leaf blowers in the towns residen-tial neighborhoods. Landscapers and theOutdoor Power Equipment Institute (OPEI)arent happy with the decision. The tradegroup lobbied the city extensively and hasloudly complained that the ban excludesnewer blower models that are much cleanerand quieter.

Palo Alto is often looked at as a modelfor legislation particularly on environ-mental issues, said Bill Guerry, an attorneywho fought the ban. The difference is thatPalo Alto made requests of the gardeners to buy the cleanest and quietest blow-ers, and participate in training programs,then challenged the manufacturers to buildcleaner and quieter products, at a cost of

literally tens of millions of dollars, and thenthey changed their mind, he told the SanFrancisco Chronicle.

The OPEI was stung by the outcome,and is warning landscapers in other mu-nicipalities to avoid antagonizing localgovernment ofcials. In most cases, cityand government ofcials, when presentedwith accurate information, (will) workwith us on legislation. OPEI president BillHarley wrote. Therefore, OPEI calls onall landscape professionals to work withcommunity residents and ofcials to prevenadversarial conditions.

More than 1,600 landscape workerswere burned, the OPEI says, when theywere certied by the city to use quieter gas-powered blowers, and bought new $500machines believing ofcials would reversethe ban. The Bay Area Gardeners Associa-tion, representing close to 1,600 gardenerswho serve Palo Alto, doesnt think so. It esti-mates that its members have lost roughly $1million in prots since the ban took effect.

The association and the gardeners alsohave the support of two companies, StihlInc. and Shindaiwa Inc., which manufacture

NATIVE NATURAL ENEMIES

The most important native natural enemyof gypsy moth is the white-footed mouseor deer mouse. This cute rodent relishesgypsy moth pupae and will also attackthe large caterpillars, skinning and guttingthem before feasting. Deer mice can have adramatic effect on the growth of gypsy mothpopulations. Evidence of their effectivenesscan be seen by comparing defoliation ofoak trees growing in lawns to those grow-ing in a woodland setting with shrubbery,logs and other cover for mice. Mice avoidcrossing exposed areas such as lawns, socaterpillars on those trees are protected and

their population soars.Birds will also feed on gypsy moth.

Chickadees and nuthatches will peck at eggmasses in winter to extract eggs. Few birdswill prey on the caterpillars as the longhairs irritate the thin skin around their eyes.However, some species with longer beaksdo feed on the caterpillars. Cuckoos (blackand yellow-billed) will congregate where

hairy caterpillars such as the gypsy mothare abundant, but they cant eat enough tobring an outbreak under control.

Beetles and other invertebrates can beimportant predators on the gypsy moth. Thebig, fast ground beetles kill many caterpil-lars that they nd in the tree tops, on thetrunks, or on the ground. Stinkbugs inject adigestive uid into the caterpillars that turnstheir tissues into a soup which the stinkbug

then sucks up. And though they appear frail,daddy long-legs are predators with a poi-sonous bite and kill many pupae (they poseno threat to humans).
