In vitro sensitivity of Botrytis cinerea Pers.:Fr. to pyrimethanil and cyprodinil in some Croatian vineyards

Anilinopyrimidines are a new group of botryticides but already endangered by resistance development. That’ s why we conducted the monitoring of the sensitivity of B.cinerea to pyrimethanil and cyprodinil in 1998 and 1999 at three sites in northern Croatia. To analyse the sensitivity of different Botrytis populations the samples were collected at trial site Kutjevo were long-term trials with continuous applications of pyrimethanil and cyprodinil have been carried since 1995 but also at two locations were these new chemistries had never been used before. Among the strains of B.cinerea collected in various Croatian vineyards during 1998 and 1999, a few exhibited a high in vitro resistance to pyrimethanil and cyprodinil. Reduced sensitivity to anilinopyrimidines could not be confirmed in vivo for any of these isolates.
