The most significant inhibitory effect of natural anthraquinone compounds on the development of pathogens occurs before the invasion of pathogens, that is, the stage before the formation of haustorium. Its mechanism of action is to significantly inhibit the germination of pathogenic conidia and the formation of appressorium, resulting in the majority of appressorium It is deformed and cannot form haustorium
