developed by the Phenylamide Fungicide Resistance Action Committee (PA-FRAC) of GIFAP

Methods are presented for monitoring the sensitivity to phenylamide fungicides of plant pathogenic fungi belonging to the Peronosporales, e.g. Phytophthora infestans, Plasmopara viticola, Peronospora tabacina, Pseudoperonospora cubensis and soil-borne Phytophthora and Pythium species. The methods are intended for practical use in the implementation of anti-resistance strategies. Methods for sterol demethylation inhibitors (DMIs), benzimidazoles and dicarboximides have already been published in Bulletin OEPP/EPPO Bulletin 21, 291–354 (1991)
