These treatments were compared with a control (no treatment) and Vitaflo®-280. Treatments were applied on six barley and six wheat seed lots contaminated with Fg at a rate of > 20% (i.e. > 20% of seeds contaminated) and/or Bs at a rate of > 50%. For all Fg-contaminated lots, the three non-chemical treatments reduced the contamination rate under the rejection threshold of 15%, which is the Danish recommendation for Fusarium spp. For Bs-contaminated lots, AAV-H reduced contamination the most, followed by AAV-L, and then by dry heat, which had no effect on barley. However, these treatments did not reduce Bs contamination under the rejection threshold of 30%, except for AAV-H in one barley lot and dry heat in one wheat lot. Also, AAV-H reduced the germination in three wheat lots and in the hulless barley AC Hawkeye, and this had negative effects on grain yield for two of the wheat lots. AAV-H had no effect on grain yield in the other lots, and neither did the other treatments in any of the lots. Dry heat was effective for controlling Fg in both cereals, whereas AAV-H showed some potential to control both pathogens, but only in covered grains. None of the treatments evaluated appears to be appropriate for reducing contamination by either pathogens in wheat and barley.","PeriodicalId":49693,"journal":{"name":"Phytoprotection","volume":"25 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2016-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84099763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nous presentons ici les resultats d’une enquete visant a determiner les regions affectees par ce ravageur et la densite de populations presentes au Quebec. Au cours des trois dernieres annees (2013-2015), le NKS a ete detecte dans 54 echantillons (32 % des champs testes) repartis dans les 10 regions productrices de soja du Quebec. Les densites de populations trouvees etaient par contre tres faibles, a la limite de detection. Parmi les regions testees, l’Estrie presentait la plus forte proportion de champs positifs (63 %). Etonnamment, cette proportion n’etait que de 7 % en Monteregie-Ouest, la ou la premiere detection a pourtant eu lieu et ou se concentre la production de soja. Dans l’ensemble, la qualite des kystes recuperes etait pauvre et le nombre d’oeufs tres faible. Meme si les populations sont encore negligeables, le NKS est bel et bien present au Quebec et il ne pourra pas etre eradique. Diverses mesures devraient donc etre mises en oeuvre afin de limiter la dispersion et l’accroissement des populations de ce ravageur important.","PeriodicalId":49693,"journal":{"name":"Phytoprotection","volume":"1 1","pages":"33-42"},"PeriodicalIF":0.0,"publicationDate":"2016-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89155233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Des chercheurs ont avance l’hypothese que l’expansion de cette maladie pourrait etre en partie liee au statut nutritif des arbres. Pour tester cette hypothese, nous avons verifie la relation entre l’apparition de cette maladie et la composition du feuillage du hetre (Fagus grandifolia Ehrh.) dans les stations du Reseau d’etude et de surveillance des ecosystemes forestiers du Quebec. Sur les 14 stations contenant du hetre, cinq presentaient des symptomes de la maladie entre 2006 et 2012. Les arbres infectes etaient en moyenne de plus grand diametre que ceux qui ne l’etaient pas. La presence de la MCH etait liee en partie a la composition foliaire des arbres (pseudo-R2 : 0,551). L’analyse indique que plus le rapport N/P du feuillage du hetre est eleve, plus la probabilite d’infection par la MCH est importante; et plus les rapports Zn/Mn et Mg/K du feuillage sont eleves, plus la probabilite d’infection par la MCH est faible. Ces rapports donnent a penser que les conditions d’acidification du sol et de drainage influencent la vigueur des arbres et, consequemment, leur vulnerabilite a la MCH.","PeriodicalId":49693,"journal":{"name":"Phytoprotection","volume":"24 1","pages":"32-37"},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87769756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of intra- and interspecific variations regarding the pathogenicity of the isolates was investigated. Results show that most of the fungal isolates caused mortality in adults and larvae. Isolates M. anisopliae INRS 705 and B. bassiana INRS 236 induced 70.3% and 65.2% of mortality in P. japonica adults, respectively, and both caused the death of about 37% of larvae. Of the 17 tested isolates, 13 caused larval mortality. However, no significant difference was found between the susceptibility of larvae to isolates from different species and those from a same species. Lecanicillium species are undoubtedly not pathogenic to adults and seem to have few effects on larvae. Based on the results obtained with the selected isolates, intra- and interspecific differences relative to the pathogenicity of the isolates appeared to be present. Overall, this study expanded the knowledge about P. japonica susceptibility towards entomopathogenic Hypocreales fungi. The implications of this study regarding the development of a biological control agent are discussed.","PeriodicalId":49693,"journal":{"name":"Phytoprotection","volume":"12 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74106456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
