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
… (squash), 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 …

Molecular marker analysis of adult plant resistance to powdery mildew in common wheat
Powdery mildew, caused by Blumeria graminis (DC.) E.O. Speer f. sp. tritici E'm. Marchal (syn. Erysiphe graminis f. sp. tritici), is one of the major diseases of wheat (Triticum aestivum L.) worldwide. The use of cultivars with resistance to powdery mildew is an efficient, economical and …

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 …

Powdery Mildew (Erysiphe cruciferarum) Affects the Allelopathic and Competitive Abilities of Invasive Garlic Mustard (Alliaria petiolata)
… found to be significantly affected negatively by powdery mildew (Erysiphe cruciferarum). While we could not significantly corroborate those findings we did find evidence that E. cruciferarum does inhibit A. petiolata’s allelopathic and competitive effects which benefits some target neighbor …

Agronomic and molecular marker mapping of brown stem rot, phytophthora root rot, and powdery mildew resistance in soybean
… of soybean in Illinois. A gene for resistance to powdery mildew, caused by Microsphaera diffusa Cke. & Pk., has also been found to be linked to a gene for phytophthora resistance. A field study was conducted to determine yield differences between isolines carrying different alleles at the locus …

Compost Tea and Milk to Suppress Powdery Mildew (Podosphaera xanthii) on Pumpkins and Evaluation of Horticultural Pots Made from Recyclable Fibers Under Field Conditions
<p>Powdery mildew (caused by <em>Podosphaera xanthii) </em>a common problem for vegetable growers, and the cost of controlling the disease with fungicides to the growers and the environment is high. An alternative approach for control using methods approved for organic production are sprays based …

Selection for Run1-Ren1 Dihybrid Grapevines Using Microsatellite Markers
Powdery mildew is a major fungal disease of grapevine worldwide, and the control of which relies on large quantities of fungicide, accounting for a considerable cost for grape growers. Genetically controlled resistance is a promising alternative to the recurrent application of chemicals.The …

Validation, Saturation, and Marker-Assisted Selection of Quantitative Trait Loci Conferring Adult Plant Resistance to Powdery Mildew in an Elite Wheat Breeding Population
Powdery mildew caused by <i>Blumeria graminis</i> f. sp. <i>tritici</i> is one of the most devastating diseases in wheat (<i>Triticum aestivum</i>) worldwide. Hypersensitive, race specific genes primarily have been deployed to control the disease, however recent efforts have shifted to breeding for …

Validation of Loci Conferring Adult Plant Resistance to Powdery Mildew in Wheat Cultivar Massey and Identification of Diagnostic Molecular Markers
Powdery mildew, caused by the pathogen Blumeria graminis (DC) Speer (Syn. Erysiphe graminis DC) f. sp. tritici, is a major disease of wheat (Triticum aestivum L.). Race-specific resistance is easily identified in the field due to its qualitative phenotype and it is easy to incorporate because it is …

IDENTIFYING HIGHLY CONSERVED PATHOGENICITY GENES IN CHESTNUT BLIGHT AND POWDERY MILDEW FUNGI AS TARGETS FOR NOVEL FORMS OF HOST RESISTANCE
… parasitica (Cp), and the Arabidopsis powdery mildew fungus, Golovinomyces cichoracearum (Gc), yielded six suspected pathogenicity genes with homologues in both species. Deletion of these genes by homologous gene replacement was attempted in Cp, with one success, TG4. The TG4-knockout …

Sunlight'S Influence On Grapevine Powdery Mildew: Direct Effects On Pathogen Development And Attendant Consequences Of Canopy Management And Vineyard Variability
Sunlight inhibits powdery mildew development through at least two mechanisms, i.e., UV radiation's damaging effects on the exposed conidia and thalli of the pathogen and through elevating the temperature of irradiated tissues to a level supraoptimal or inhibitory for pathogen development. …
