Název v původním jazyce

Disease impact and pathogenicity variation in Czech populations of cucurbit powdery mildews

Popis výsledku v původním jazyce

Distribution, disease impact and pathogenic variability of cucurbit powdery mildew was monitored on cucurbitaceous crops in the Czech Republic (CR) during the years 2001 and 2002. Occurrence of powdery mildews, Golovinomyces cichoracearum s.l. (Gc) and Podosphaera xanthii (Px), was monitored at 84 locations in 2001 and 109 locations in 2002. The highest frequency of powdery mildew infection was observed on Cucurbita pepo (90% of locations) and Cucurbita maxima (84%), but a low frequency was observed onCucumis sativus (4 %), and no infection was observed on Citrullus lanatus. A medium level of disease intensity (25#50%) occurred on Cucurbita spp. The pathogens were identified on 237 samples of leaves with symptoms of powdery mildew originating from 9 regions and 30 districts of the CR. Gc occurred alone at 90% of the locations, Px occurred alone at only 2% and a mixture of both pathogens was found at 8% of locations. Pathogenic variability (pathotypes, races) was determined for 89 isol
