Occurrence of Ampelomyces quisqualis on the cucurbit powdery mildew species in the Czech Republic
Original language description
From 2002 to 2006, in the Czech Republic (CR), 585 leaf samples with powdery mildew symptoms collected from cucurbits (mainly from Cucurbita pepo, Cucurbita maxima, Cucumis sativus) were microscopically examinated for presence of hyperparasitic fungus Ampelomyces quisqualis Ces. (Aq). Identification of cucurbit powdery mildew species (Golovinomyces cichoracearum /Gc/, Podosphaera xanthii /Px/) was carried out by microscopic examination of the morphological characters of dry conidia in a 3% KOH solution.In total of 443 samples was determined as Gc, 106 samples as mixed infection (Gc, Px) and 36 samples as Px. Aq was detected on 12% of collected samples from the CR. Pycnidia of Aq were recorded mainly on Gc hyphae and basal cells of conidiophores (12%)or on mixed infection (Gc, Px) (14%), on Px only sporadic.
