Název v původním jazyce

Fungicide resistance in Czech populations of cucurbit powdery mildews

Popis výsledku v původním jazyce

A total of 108 isolates of cucurbit powdery mildew (CPM) fungi, 78 Golovinomyces cichoracearum (Gc) and 30 Podosphaera xanthii (Px), originating from 9 Czech regions and 22 districts of the Czech Republic were collected in the years 2001-2004. These isolates were screened for tolerance and/or resistance to the three frequently used fungicides (fenarimol, dinocap, benomyl). Fungicide sensitivity was determined by a modified leaf-disc bioassay with five concentrations. Fungicide effectiveness was significantly different. Fenarimol was the most effective and all isolates of both CPM were controlled by the recommended concentration (36 mikrog a.i./ml). Some isolates expressed resistance (profuse sporulation) or tolerance (limited sporulation) to lower concentrations (9.6 mikrog a.i. /ml, 18 mikrog a.i. /ml). Specific temporal variation in tolerance/resistance was observed, with some isolates of Gc from 2002 showing tolerant or resistant reactions to these low fenarimol concentrations, howe
