Testing the sensitivity of Venturia inaequalis to pyrimethanil from selected orchards in Czech Republic
Original language description
The fungus Venturia inaequalis (Cooke) G. Winter (1875) (anamorph - Spilocea pomi Fr., 1825) causes a disease in apple orchards worldwide – apple scab. It is the most serious and economically important disease of apple trees (Malus x domestica Borkh.). In order to ensure reliable protection against apple scab, it is necessary to apply 15 to 20 fungicide sprays during the season. Intensive use of chemical protection may lead to its failure, which may be due to lower sensitivity, or even resistance of the fungus. One group of fungicides commonly used are known as anilino-pyrimidines (AP), with a moderate risk of developing resistence. Mutations in the regulation of methionine biosynthesis are a potential cause of AP fungicide resistance. Especially fungal pathogens such as V. inaequalis and Botrytis cinerea showed lower sensitivity or resistance to anilinopyrimidines in fruit crops. Aim of this study was to find out the current state of sensitivity of V. inaequalis populations to the active substance pyrimethanil (compound Mythos 30 SC) from selected commercial orchards in the Czech Republic reporting nonsatisfactory management of apple scab.
