Control of Erysiphe pisi Causing Powdery Mildew of Pea (Pisum sativum) by Cashewnut (Anacardium occidentale) Shell Extract
The effect of methanolic extract of cashewnut (Anacardium occidentale) shell extract was seen on conidial germination of Erysiphe pisi and powdery mildew development in pea (Pisum sativum). Maximum conidial germination inhibition of E. pisi on glass slides was observed at 300 ppm. Similar effect on floated pea leaves was observed after 48 h at the same concentration. Conidial germination on int...
متن کاملWater Soluble Antifungal Metabolites of Pea (pisum Sativum) Leaves Determine Infection by Erysiphe Pisi
Antifungal activity of water soluble exudates of pea leaves was assayed. Exudates of different nodal leaves were collected by dipping them in sterilized distilled water for different length of time and conidial germination of four non-pathogenic to pea fungi (Alternaria solani, Curvularia lunata, Helminthosporium penniseti and H. echinocloa) and one pea pathogenic to pea fungus (Erysiphe pisi) ...
متن کاملFoliar Application of Plant Growth-Promoting Rhizobacteria Increases Antifungal Compounds in Pea (Pisum sativum) Against Erysiphe pisi
Systemic effect of two plant growth-promoting rhizobacterial (PGPR) strains,viz., Pseudomonas fluorescens (Pf4) and P. aeruginosa (Pag), was evaluated on pea (Pisum sativum) against the powdery mildew pathogen Erysiphe pisi. Foliar spray of the two PGPR strains was done on specific nodal leaves of pea and conidial germination of E. pisi was observed on other nodal leaves,distal to the treated o...
متن کاملDiscovery of a Novel er1 Allele Conferring Powdery Mildew Resistance in Chinese Pea (Pisum sativum L.) Landraces
Pea powdery mildew, caused by Erysiphe pisi D.C., is an important disease worldwide. Deployment of resistant varieties is the main way to control this disease. This study aimed to screen Chinese pea (Pisum sativum L.) landraces resistant to E. pisi, and to characterize the resistance gene(s) at the er1 locus in the resistant landraces, and to develop functional marker(s) specific to the novel e...
متن کاملCharacterization of resistance mechanisms to powdery mildew (Erysiphe betae) in beet (Beta vulgaris).
Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in ...
