Antifungal Activity of Chrysoeriol 7 and Cochlioquinone 9 from Riec (Oryza sativa L.) Inoculated with WBPH

Rice (Oryza sativa L.) is the main food crop for more than 50% of the world’s population. however, rice is easily attacked by pests and pathogens. Agriculture is dependent on chemical fertilizers and organic synthetic pesticides. As the problems of pesticides have begun to emerge around the world, research to explore eco-friendly materials has been actively conducted. In this research, we extracted of Chrysoeriol 7 (C7) and cochlioquinone 9 (C9) from rice, and investigated the antimicrobial activity against rice pathogens to judge the possibility of use as an environmentally friendly biopesticide.
