Popis: Decreased sensitivity of Sphaerotheca fuliginea (Schlecht.) Poll. (powdery mildew of cucurbits) to ergosterol-biosynthesis inhibitors (EBIs) which inhibit 14C-demethylation, has been found in areas where these fungicides have been used frequently for several seasons. Relatively low sensitivity was associated with poor disease control in some cases, especially in field-grown cucurbits. Isolates less sensitive to EBIs which inhibit 14C-demethylation were sensitive to fungicides with different modes of action. In order to ensure their continued usefulness it is recommended to reduce selection pressure by using EBIs inhibiting 14C-demethylation during only a part of the growing season.
