Phenylpyrroles
Phenylpyrroles are chemical derivatives of pyrrolnitrin, a secondary metabolite produced by some bacteria from tryptophan (Floss et al., 1971). It was isolated for the first time from Pseudomonas pyrrocinia in the 1960s (Arima et al., 1965) and showed strong antifungal activity against various animal and … See more Jespers et al.

WebThe chemical control of Botrytis spp., and especially B. cinerea the causal agent of grey mould on many crops, can be achieved by several families of fungicides. Among those affecting fungal respiration, the oldest ones are multi-site toxicants (e.g. dichlofluanid, thiram); newer ones are uncouplers (e.g. fluazinam), inhibitors of mitochondrial ... WebAbstract Botrytis cinerea has a high risk of developing resistance to fungicides. Fludioxonil, belonging to phenylpyrroles, has been used for more than three decades, however, only few cases of field resistance against phenylpyrroles have been reported.
