Methanol extracts from 25 leguminous seeds were tested for their fungicidal activities toward six phytopathogenic fungi, using whole plant test in a greenhouse. The efficacy varied with both the plant pathogen and legume species used. At 5 mg/pot, potent fungicidal activities were produced from extracts of Cassia obtusifolia, Glycine max var. solitae, G. max var. yagkong, G. max var. hooktae, Phaseolus multiflorus, P. radiatus var. aurea, and Vigna sinensis against Botrytis cinerea, Puccinia recondita, and Erysiphe graminis. These seed extracts were highly effective against three B. cinerea strains resistant to carbendazim, procymidone, and diethofencarb. All leguminous seed extracts revealed weak or no fungicidal effect against Rhizoctonia solani, Pyricularia grisea, and Phytophthora infestans. As a naturally occurring fungicide, leguminous seed-derived materials described could be useful as new fungicidal products against various plant diseases induced by phytopathogenic fungi.
