Inheritance of powdery mildew resistance genes in 10 winter wheat lines
… from the 1982 International Winter Wheat Mildew and Rust Nurseries were studied to characterize gene number and mode of inheritance of powdery mildew resistance. Two experiments were conducted: 1) each of the lines was crossed to the susceptible cultivar Chancellor, which lacks any known’ …

Identification of fungal species causing powdery mildew on cucurbits, determination of the genetic and pathogenic variations of the fungi and their sensitivity to major powdery mildew fungicides
… and Citrullus lanatus (watermelon). Powdery mildew is an annually-occurring disease of cucurbits, which causes yield losses up to 50% in Illinois and worldwide. Podosphaera xanthii and Golovinomyces cichoracearum are known as the causal agents of cucurbit powdery mildew. No reported …

Epidemiological studies and sustainable approaches for the control of strawberry powdery mildew
Strawberry powdery mildew, caused by Podosphaera aphanis, is one of the most destructive diseases of strawberries worldwide, particularly under protected cultivation. Difficulties in detecting and managing early infections result in rapid development and yield losses up to 70%. Control still relies …

Investigating the role of downy mildew effectors in host resistance and susceptibility
… eukaryotic plant pathogens such as rusts and mildews can deliver “effector” proteins directly into plant cells in order to manipulate specific defence responses and processes. Hyaloperonospora arabidopsidis (Hpa) is a haustorium-producing biotrophic oomycete pathogen that causes downy mildew …

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 …

Integrating Genomics and Metabolomics to Inform Breeding for Powdery Mildew Resistance in Grapevine
Two powdery mildew resistance loci have been identified using pedigree-connected F1 mapping families at the University of Minnesota grape breeding program. A consensus linkage map of the resistant parent (MN1264) was developed for genetic mapping. The resistance loci were mapped on chromosomes 2 …

Strawberry Powdery Mildew Caused by Podosphaera aphanis: Fungicide Resistance and Host Plant Resistance
<p>Strawberry powdery mildew, caused by <em>Podosphaera aphanis</em>, affects leaves, fruit, and runners of strawberry plants. Infected leaves have reduced photosynthetic capability and infected fruit become unmarketable. Both of these factors translate to economic loss for the grower and therefore …
