Abstract: China’s cropping area and yield of pepper (Zanthoxylum bungeanum) rank the first in the world. The green control of pests and diseases is one of the key problems to be solved in Hancheng, the largest producer of Z. bungeanum in China. In this study, we investigated and analyzed the occurrence and key points for prevention and control of Agrilus Zanthoxylumi and gummosis. A. Zanthoxylumi and gummosis were controlled by injection, spraying, rossing and smearing wood tar, and tree trunk injection. The results showed that the key period for the control of A. Zanthoxylumi and gummosis was early June. Using 5% pyrethrins EC in tree trunk injection combined with rossing and smearing wood tar was the best method to control A. Zanthoxylumi and gummosis, which resulted in a 100% comprehensive pest control efficiency and effectively improved the quality of Z. bungeanum so as to help achieve high economic benefits and protect the ecological environment. This study provides a new idea for biopesticide control of pests and diseases of Z. bungeanum.

Key words: Agrilus Zanthoxylumi, gummosis, biopesticides, ecological agriculture, food safety
