Isoflavones extracted from Millettia pachyloba prevent the infection of the rice blast fungus by inhibiting its conidial germination and appressorium formation

Abstract

The ascomycete Magnaporthe oryzae is a destructive phytopathogenic fungus that causes rice blast disease and can greatly reduce rice yields. Due to the widespread use of synthesized chemical fungicides and the frequent occurrence of fungicide resistance and environmental pollution as a result, it has become increasingly urgent to develop environmentally friendly biocontrol alternatives, including plant crude extracts.
