Sažetak

Botrytis gray mold caused by Botrytis cinerea is an important pathogen of grapevines all over the world. In order to determine the intensity of B. cinerea attack on mature grapes and efficiency of botryticides (cv. Traminac - iprodion, pyrimethanil, fludioxinil + cyprodinil; cv. Graševina - fenhexamid, fludioxinil+cyprodinil, tebuconazol+diclofluanid) a two-year experiment (2001-2002) was set up on locations Mladice (Traminac) and Škomić (Graševina). By evaluation of the intensity of B. cinerea infection on the Graševina and Traminac grapes the strongest infection determined on the control, and the weakest on the variant with botryticides Switch. Comparison of infection intensity on the Traminac grapes with the Graševina grapes led to no differences concerning the sensitivity of varieties. The disease intensity primarily depended on climate conditions. Both experimental years were charactized by the quantity of precipitation in the vine-yards which were in favour of the high humidity allowing high disease intensity.
