WebApr 15, 2003 · Abstract. Fenpiclonil and fludioxonil are two phenylpyrrole fungicides related to pyrrolnitrin, a natural antibiotic first isolated from Pseudomonas pyrrocinia. Both … 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.

WebDec 10, 2024 · Phenylpyrroles are based on pyrrolnitrin, which are secondary metabolites produced by Pseudomonas pyrrocinia having antifungal properties (Floss et al. 1971 ). Pyrrolnitrin is instable under light; therefore, it is unsuitable to use practically in disease control (Corran et al. 2008 ). WebNo effect of phenylpyrroles resistance mutation(s) on fungitoxicity of triazoles, benzimidazoles, anilinopyrimidines, phenylpyridinamines, strobilurin-type fungicides and to the non site-specific inhibitors chlorothalonil and maneb was observed. The above mentioned data indicate, for the first time, the potential risk of increased aflatoxin ...
