Název v původním jazyce

Resistance to fungicides in cucurbit powdery mildew populations in the Czech Republic.

Popis výsledku v původním jazyce

Twenty five isolates of cucurbit powdery mildews (Golovinomyces cichoracearum (Gc) and Podosphaera xanthii (Px) (20 Gc, 5 Px)), collected in the year 2001 in 8 regions of the Czech republic (CR), were used for surveying of fungicide-resistance and/or tolerance. The effectivity of three fungicides (Rubigan 12 EC, Karathane LC, Fundazol 50 WP) were tested. In vitro leaf disc laboratory method was developed for this purpose. Discs were prepared from adult plants of Cucumis sativus cv. Stela F1. There wereproved significant differences in effectivity between fungicides. Rubigan 12 EC showed the best effectivity and gave control of powdery mildew at dosage 0.03% (i.e. optimal concentration). Karathane LC expressed only partial effectiveness, 64% of isolates were controlled even by the 0.008% solution of this fungicide, 28% of isolates sporulated on concentrations lower than optimal and 8% of isolates overcome the registered concentration (0.03%). Fundazol 50 WP was not effective in every s
