Description

technical field [0001] The invention relates to the technical field of tea pest control, in particular to a powder for preventing and controlling tea leafhoppers. Background technique [0002] The tea leafhopper has 9 to 11 generations a year, mostly overwintering as adults on tea trees or winter crops (beans), weeds and other plants, and can overwinter in various states in South China. When the temperature turns up in the early spring of the next year, the adults start to feed and supplement nutrition, and the tea trees start to lay eggs and reproduce after they germinate. At the end of autumn and the beginning of winter, the buds of tea trees stop growing, and the adults stop laying eggs and enter the overwintering period. Adults have the habit of successively conceiving eggs and laying eggs in batches, especially the oviposition period of overwintering adults can be as long as 1 month. Generational overlap is therefore severe. Leafhoppers have two occurrence peaks thro...
