Frequency of transposable elements and fungicide resistance in Botrytis cinerea populations on strawberries from Aydin and Mersin provinces

Strawberry is a delicious fruit that can be consumed fresh and can be used in industry. One of the important factors that effects yield is the plant protection problems. Because of the metabolites that fungi produce, especially in foods, they pose a threat to health and also cause economical problems. Botrytis cinerea causes grey mold disease in over 200 plant species. For the purpose of detecting transposon frequencies and fungicide resistance samples were collected from three different localities from Aydın province, and from two different localities from Mersin province. Samples were incubated on PDA medium and then isoleted from mixed cultures. Morphological and molecular identification of the samples were made. Transposon sites were amplified by PCR. In total 154 B.cinerea samples were isolated of which consists transposa 20.1 %, boty 46.1 %, flipper 10.4 % and vacuma 23.4 %. In Aydın population transposa 19.5 %, boty 48.3 %, flipper 9.2 % and vacuma 23.0 %, in Mersin transposa 20.9 %, boty 43.3 %, flipper 11.9 % and vacuma 23.9 % was found. In spore stage tests of fungicide tests cyprodinil was found the most effective while fenhexamid was found the less effective. In mycelium stage tests of fungicide tests fenhexamid was found the most effective with the lowest concentration while carbendazim was found the less effective with the highest concentration. Flipper group was found most sensitive to the tested fungicides.
