[Method] Long-term observation was con- ducted on cultivation methods of Siraitia grosvenori in the gardens in Longjiang Vil- lage of Yongfu County to conclude the prevention methods. [Result] Siraitia grosvenori yield can be reduced by nine diseases, such as root knot nematode dis- ease, and eight pests, such as Brachytrupes portentosus. [Conclusion] It would be effective for prevention of diseases and pests and guarantee quality and yield of Luohan guo to manage the gardens dominated by biological control and supple- mented by pesticide as per crop rotation.展开更多
