FEDERAL PESTICIDE REGULATIONSYSTEM REVISEDOn February 3, 1992, the feder-al government announced, underCanada's Green Plan, animproved regulatory system forpesticides that enhances pro-tection of human health and theenvironment while allowing ind-ustry to have access to thepest management tools it needsto remain competitive.

Changes to the system are basedon the recommendations con-tained in the final report ofthe Pesticide RegistrationReview Team, appointed by theMinister of Agriculture to exa-mine Canada's pesticide regis-tration system. The teamincluded representatives ofhealth, environmental, laborand consumer groups and thefarm, forestry, and chemicalindustries.

transfer, may be used to createother multiple-use strains ofBacillus thuringiensis.

Field tests prove that B. t •loses its effectiveness afterabout 10-12 hours because sun-light degrades the toxin-carry-ing protein crystals within thecells. Advances in increasingthe life span of the bioinsect-icide have also been accom-plished by encapsulating thesurface of B. t. cells with aprotective coating thatincreases the bacteria's resis-tance to UV rays. Presentlythe toxin-producing crystalsvary from cell to cell, causingvariable field performance.This also makes it difficult toobtain pure strains. Research-ers are looking for linksbetween chemical resistance andB.t. resistance in an effort toretard an insect's ability tobuild tolerance to B.t.

Fungus diseases and theirpractical importance againstarthropods

Biological control studies withDeuteromycetes are conducted bythe Federal Research Stationfor Agronomy, in Zurich-Recken-holz, Switzerland. They haveused the fungi Beauveria brong-niartii to control white grubsfor the last fifteen years.The use of blastospores hasalso reduced the populationdensities of swarming adults atmost sites. Beauveria brongni-artii has proven to be suffi-cient for meadows and arableland, but not for cash cropslike orchards. A method toinfect grubs with the fungus isbeing developed. One methodwould be to drill seed the soilwith inoculated barley kernels.

Beauveria brongniartii was re-cently provisionally registeredas a plant protection agent inswitzerland.

Polymer-type antitranspirantsshow promise as biofungicides

Any substance applied to aplant specifically to slowtranspiration is called an ant-itranspirant. The three gen-eral types are: chemical com-pounds such as phenylmercuricacetate or abscisic acid thatcause stomata to close as partof interference with plant met-abolism; compounds such askaolinite that reflect sunlightand therefore lower leaf tem-peratures; and polymers appliedto physically cover thestomata.

Polymer-type antitranspirantsare non-toxic, biodegradable,and inexpensive compared tochemical fungicides. Unlikeconventional fungicides, theiraction against pathogens isnon-specific and plants are notlikely to build-up a resis-tance. The polymers used onplants are waxes, polyterpenes,silicones, latex compounds,acrylic esters, and high mol-ecular weight alcohols. Threeimportant uses of anti-transpi-rants are relief of wilt andwater stress, improvement ofwater use efficiency, and pro-tection against fungal dis-eases.

Diamondback moth shows resis-tance to Bacillus thuringiensis

Research scientists at the Uni-versity of Valencia in Spain,and the Plant Genetic Systemsin Ghent, Belgium, have deter-mined the physiological basisof the resistance to Bacillusthuringiensis in thediamondback moth, Plutella xyl-ostella, especially in mothsfrom the Pacific area of theworld.

Larvae from populations in thePhilippines showed 200 timesmore resistance to CrylA(b)toxin than to a control popula-tion. Tests showed that theprotein failed to bind to thebrush-border membrane in thegut of the Philippines moth.When larvae of the diamondbackmoth is susceptible to B. t . ,the protein binds in the mem-brane, causing physiologicaldisorders leading to death.The research may improve theuse of B.t. toxins in thefuture.

Weed-free soybeansResearchers at the SouthernWeed Science Laboratory, Stone-ville, Mississippi, have ident-ified a strain of Fusarium oxy-sporum, a well known plantpathogen, that attacts manyleguminous weeds, but not soy-beans.

Tests indicate that sicklepodCassia obtusifolia, hemp sesba-nia Sesbania exaltata, and cof-fee senna Cassia occidentalis,problems in some soybean crops,can be affected by the fungus.If the fungus attacks weedswithout affecting the soybeancrop, a single treatment atplanting time may be all thatis required to control weedsthroughout the growing season.Once the fungus is cultured,and the formulation for apply-ing it is determined, an econ-omical mycoherbicide may beavailable.

Beauveria bassiana to controlgrasshoppers

The possibility of controllinggrasshoppers, a recurrent prob-lem on the prairies, with lesschemical insecticide is gettingcloser. A fungus pathogen Bea-uveria bassiana, is being inve-stigated for its potential as abiological control agent ofgrasshoppers. A strain of thefungus was tested at the Agri-cuI ture Canada Research Stationin Lethbridge. In July, 1991,a field trial was conducted onland owned by an organic wheatgrower near Vulcan, Alberta.within nine days, the number ofgrasshoppers in the treatedfields was reduced by 60%.This is a promising result inthe search for a biologicalmethod for controlling grass-hoppers. If the fungus provesto be a commercially feasiblecontrol agent, a full evalu-ation of its use will berequired before its registra-tion.

Biological control of codlingmoths

Field trials on the use of gra-nulosis virus for Cydia pomone-lla (codling moth) control onapples, were conducted at theHarrow Research Station. Theyhave determined the applicationrate of the virus per hectare,and the number of applicationsthat would be required to befully effective in orchards.

Three applications wererequired in regions where therewas one generation annually and5-7 applications where therewas a second generation of themoth. Preliminary studies ind-icated that 50% inactivity ofthe virus occurred after 2 dayson foliage and 80% after 10days.

PLANT PATHOGENIC BACTERIAIDENTIFIED FASTER ANDSPECIFICALLY

New technology developed byBiolog Inc., Hayward, Califor-nia, enables plant pathogenicbacteria to be identifiedfaster and more specifically.The system was tested at thePlant Diagnostic Lab in Clover-dale, British Columbia, andthe Biolog system gave

accurate and repeatable identi-fications with known bacterialspecies. The system is incor-porated into the Plant Diagnos-tic Lab framework and hasincreased the bacterial identi-fication capabilities of theLab. This means Canadiangrowers can start controlmeasures earlier, and can usethe most effective disease man-agement techniques for the par-ticular bacterial species iden-tified.

STICKY BARRIERSGrowers can prevent pests, thatdo not fly, access to foliageby applying sticky barriers tothe trunks of susceptibleplants. Barriers can be cre-ated by painting or spraying asticky adhesive such as Tangle-foot@ or Stickem@ in a wideband around the trunks of woodyshrubs. The bands must bechecked monthly, and the adhes-ive reapplied when the barrierbands become ineffective due tothe accumulation of pests, dustand other debris. When a newapplication of adhesive isneeded, it is recommended thatit be applied either above orbelow the previous barrierband. In some cases, a stripof fabric tree wrap can besecured to the trunk and theadhesive can be applied to itssurface. Careful attentionmust be given to any foliagetouching the ground or an adja-

WEEDS - GIVE THEM LIGHTReseachers at Montana StateUniversity, Bozeman, havemounted bright lights on a cul-tivator to determine if theextra flash of light will trig-ger weed seeds to germinatesoon after the cultivator turnsthem deeply into the soil.

The theory behind the researchwas inspired by the fact thatmany weed seeds need light togerminate, some species requirevery little light, and theforced additional light mayincrease germination rate. Theseeds subjected to extra lightcould die below the soil sur-face, before the seedling evenhas a chance to emerge.

HIGHLIGHTS OF MEETINGInternational Symposium onBiotechnologies andEnvironment: For SustainableDevelopmentThe symposium was held Septem-ber 23-26, 1991, at the Univer-sity of Montreal, Quebec. Itwas organized within the frame-work of UNESCO'S Global Networkof Microbial Resource Centres.

IDENTIFICATION PLUS RAPIDE ETSPECIFIQUE DES BACTERIESPHYTOPATHOGENES

Une nouvelle technologie miseau point par Biolog Inc. aHayward en Californie permetune identification plus rapideet plus specifique des bacte-ries phytopathogenes. Le sys-teme Biolog, qui a ete mis al'essai au Laboratoire de diag-nostique des maladies des plan-tes a Cloverdale en Colombie-Britannique, a donne une iden-tification exacte et repetableavec des especes bacteriennesconnues. On l'a integre dansIe cadre de recherche au Labo-ratoire, lequel a vu accroitresa capacite d'identificationdes bacteries. Cette perceetechnologique permettra auxproducteurs canadiens de proce-der plus tot a des traitementset d'utiliser ceux qui sont lesplus efficaces contre les espe-ces bacteriennes specifiquesqui ont ete identifiees.

Des experiences indiquent queCassia obtusifolia, Sesbaniaexaltata et Cassia occiden-talis, sont des problemesd'adventices preoccupants danscertaines cultures de soja etpeuvent etre infectees par lechampignon. Si le champignonattaque les mauvaises herbessans nuire au soja, un seultraitement au moment des semissuffira peut-etre aleseliminer pour toute la saisonde croissance. Des que lechampignon aura ete mis enculture, et que sa formulationaura ete etablie, on disposera

Le Beauvaria bassiana pour1utter contre 1a sautere11eLa possibilite de lutter contrela sauterelle (un problemecyclique dans les prairies)avec le moins possibled 'insecticide chimique, devientune approche de plus en plusaccessible. Un champignonpathogene, Beauveria bassianaest a l'etude pour evaluer sonpotentiel comme agent de luttebiologique contre lasauterelle. Une souche de cechampignon a ete evaluee a laStation de recherchesd'Agriculture Canada aLethbridge. Au mois de juillet1991, un essai au champs a eteeffectue sur une terreappartenant a un agriculteurbiologique cultivant le blepres de Vulcan en Alberta. Enmoins de neuf jours le nombrede sauterelle a diminue de60 %. Ces resultats sont desplus prometteur pour larecherche des methodes en luttebiologique contre la saute-relle. Si ce champignons'avere etre un agent de luttecommerciale possible, uneevaluation complete de sonutilisation sera requise avantson homologation.

Les anti-transpirants de typepolymeres sont non toxiques,biodegradables et economiquescomparativement aux fongicideschimiques. Comme leur actioncontre les agents pathogenesest non specifique, contraire-ment aux fongicides classiques,il est peu probable que lesplantes acquierent uneresistance a ces composes. Lespolymeres utilises sur lesplantes sont : les cires, lespolyterpenes, les silicones,les composes au latex, lesesters acryliques et lesalcools a haut poids molecu-laire. Les anti-transpirantsservent principalement a com-battre Ie fletrissement et Iestress hydrique, a rendrel'utilisation de l'eau plusefficace et a proteger lesplantes contre les maladiesfongiques.

Resistance de la fausse-teignedes cruciferes au Bacillusthuringiensis

Des chercheurs a l'Universitede Valence en Espagne et lesSystemes phytogenetiques aGhent en Belgique ont decouvertIe mecanisme physiologique dela resistance au Bacillusthuringiensis chez lafausse-teigne des cruciferes,Plutella xylostella, notammentdans des populations de laregion du Pacifique du globe.

Aux Philippines, des larves ontmanifeste 200 fois plus deresistance a la toxine Cry1A(b)que la population temoin. Desexperiences ont revele quecette proteine ne parvenait pasa se fixer a la membrane abordure en brosse de leur tubedigestif. Or, quand les larvesde la fausse-teigne sontsensibles a l'effet du Bacillusthuringiensis, on a constateque la proteine se fixait acette membrane, entrenant desdesordres physiologiques mor-tels. Ces travaux pourraientameliorer I 'utilisation destoxines du Bacillus thuringi-ensis dans l'avenir.

REVISION DU SYSTEME FEDERAL DEREGLEMENTATION DES PESTICIDESLe 3 fevrier 1992, Ie gouverne-ment federal a annonce, sous IePlan Vert du Canada, la mise enplace d'un nouveau systeme dereglementation des pesticidesqui garantitune meilleureprotection de la sante humaineet de la qualite de l'environ-nement tout en permettant ausecteur agricole de s'equiperdes moyens de lutte anti-parasitaire necessaire pourdemeurer concurrentiels.Les modifications apportees ala reglementation donnent suiteaux recommandations contenuesdans Ie rapport final del'Equipe d'examen du processusd'homologation des pesticidesmise sur pied par Ie ministrede l'Agriculture pour examinerIe systeme canadien d'homolo-gation des pesticides. Cetteequipe se composait de repre-sentants des groupes interessesa la sante publique, a l'envi-ronnement, au monde du travailet a la defense des consom-mateurs, ainsi que de repre-sentants des secteurs del'agriculture, des forets etdes produits chimiques.Pour de plus amplesrenseignements, appeler sansfrais :Le systeme federal dereglementation des pesticides,au 1-800-267-1238.LUTTE BIOLOGIQUENouveaux hybrides de Bacillusthuringiensis

Le Dr G. Dively, professeuragrege en entomologie al'Universite du Maryland, a misau point des souches geneti-quement ameliorees du bio-

insecticide Bacillusthuringiensis (B. t. ). .pourcombattre plusieurs insectes ala fois. Des chercheurspeuvent maintenant elever lescoleopteres et les chenilles,produisant des toxines pourfabriquer une seule et memesoudhe de B.t. qui tuera le~deux types d'insectes.Lenouvel hybride s'appele Foil etIe procede, connu sous Ie nomde transfert deconjugue, peutservir a creer d'autres souchesde B.t. a usage multiple.Les essais sur Ie terrainrevelent que Ie B. t. devientinefficace au bout de 10 a 12heures a cause de la photo-degradation des cristaux deproteines porteurs de toxine, al'interieur de la cellulebacterienne. On a aussi reussia allonger la duree de vie dubio-insecticide en enveloppantla bacterie d'une capsuleprotectrice qui augmente saresistance aux rayons ultra-violets. A l'heure actuelle,comme les cristaux varientd'une cellule a l'autre, il estdifficile d'obtenir des souchespures, d'ou un rendement vari-able sur Ie terrain. Des cher-cheurs etudient l'existenced'un lien possible entre laresistance chimique et laresistance du B.t. afin de re-tarder l'acquisition chez lesinsectes d'une tolerance a cebio-insecticide.
