Resistance to acylalanine fungicides in Phytophthora megasperma f.sp. medicaginis



Resistance to acylalanine fungicides in Phytophthora megasperma f.sp. medicaginis



Netherlands Journal of Plant Pathology 87(1): 11-24



Isolates resistant to metalaxyl were obtained by mycelial adaptation and by mass selection from zoospores, either untreated or treated with UV irradiation or a chemical mutagen. In an assay with 1-week-old lucerne seedlings all 19 spontaneously obtained isolates showed relatively low resistance to the fungicide and were less virulent than the original isolate.
