Antimicrobial Activity of Chrysoeriol 7 and Chochlioquinone 9 White-Backed Planthopper-Resistant Compounds Against Rice Pathogenic Strains

摘要

This study is an important contribution to the development of biopesticide materials for controlling major pathogens in rice. Chrysoeriol 7 and cochlioquinone 9, which repel the white-backed planthopper, were extracted from rice and their antimicrobial activity was investigated. The results show they are effective in limiting the growth of pathogens of the genera Fusarium, Cladosporium and Pythium. This shows that they have great potential as an alternative to chemical pesticides and is also thought to be helpful in development of eco-friendly agriculture.
