Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… the sensitivity of grape downy mildew (DM, Plasmopara viticola) and powdery mildew (PM, Erysiphe necator) to commonly used single-site fungicides in Virginia and nearby states. DM and PM isolates were collected from 2005 to 2007. In grape leaf disc bioassays, 92% of the DM isolates were QoI …

Épidémiologie comparative des deux clades de Plasmopara viticola (clades riparia et aestivalis) prévalents dans l’est du Canada
Le mildiou de la vigne est causé par Plasmopara viticola, un oomycète parasite obligatoire, originaire de l’Amérique du Nord. Ce pseudochampignon se développe sur tous les organes verts en croissance de la vigne et ne s’attaque pas aux tissus aoûtés. Lorsque les conditions sont favorables, les …

NOVEL PERSPECTIVES IN THE CONTROL OF PLANT PATHOGENIC OOMYCETES
… Phytophthora capsici, Pythium ultimum, and Plasmopara viticola. An innovative protocol combining flow cytometry and cell sorting was successfully designed and employed to analyze the composition and efficiency of the secondary inoculum of the oomycete pathogen Plasmopara viticola, offering …

Advancing Sustainable Grape Downy Mildew Management: Biopesticide Trials and Risk Assessment System
Grape downy mildew, caused by Plasmopara viticola, significantly damages grape crops (Vitis spp.), reducing yields by up to 75% in unprotected vineyards. The Eastern US faces limited fungicide options due to resistance development and potential legal restrictions on EBDC and captan. The first study …

Genome editing for engineering resilience to climate changes in grapevine
… in terms of resistance to the harmful oomycete Plasmopara viticola, the causal agent of downy mildew, which enter in the plant leaf through the stomata. Leaf disc assays to test Plasmopara viticola pathogenicity were carried out on VviEPFL9-1 and VviEPFL9-2 edited plants of ‘Sugraone’ and …

Characterization of fungicide resistance in grape powdery and downy mildew using field trials, bioassays, genomic, and transcriptomic approaches: quinoxyfen, phosphite, and mandipropamid
… and sporulation activity. Grape downy mildew (Plasmopara viticola), another important grape pathogen, is commonly controlled by phosphite fungicides. A field trial and laboratory bioassays were conducted to determine whether P. viticola isolates from vineyards with suspected control failures …

Evaluation of soybean cyst nematode (SCN) resistance in perennial glycine species and genome-wide association mapping and genomic prediction study for SCN resistance in common bean and prediction of the short distance movement of soybean rust urediniospores through machine learning
… economic loss caused by downy mildew of grapes (Plasmopara viticola) in the Mediterranean in 1865, to the loss of the valuable banana cultivar ‘Gros Michel’ caused by Fusarium oxysporum Schlect. f. sp. cubense, plant diseases have caused significant historical and economic importance. The goal of …

INTEGRATING FUNGICIDE RESISTANCE MONITORING AND FORECASTING MODELS FOR THE PRECISION MANAGEMENT OF GRAPEVINE DOWNY MILDEW
… downy mildew, caused by the biotrophic oomycete Plasmopara viticola, is one of the most destructive, with the potential to cause severe yield losses under favourable environmental conditions. In Europe, the widespread cultivation of a highly susceptible host and climatic conditions characterised …
