Problems solved by technology

However, from practical application, chemical pesticide control does not meet the production requirements of green tea; agricultural control and physical control workload is large, and the control effect is not ideal; botanical pesticides such as matrine, rotenone, pyrethrum, etc. are used to control pests, but The control of botanical pesticides only targets a specific pest, and the spectrum of resistance to pests is narrow, so it is often necessary to cooperate with other chemical pesticides for control

Abstract

The invention provides a microbial pesticide for preventing and controlling tea pests and diseases and an application thereof. The pesticide is cultivated by bacillus subtilis, trichoderma, bacillus thuringiensis, streptomyces lavendulae, Wuyimycin, bean dregs and sucrose water. The microbial pesticide has a wide range of preventing pests and diseases, has a significant effect on the prevention and control of tea diseases, and meets the production requirements of green pollution-free tea.

Description

technical field [0001] The invention belongs to the technical field of tea planting, and in particular relates to a microbial pesticide for preventing and controlling tea plant diseases and insect pests and an application thereof. Background technique [0002] Tea culture has a long history in our country, both in terms of planting and management have mature technical concepts, but with the rapid development of the market economy, people's living standards are constantly improving, and the requirements for green and pollution-free tea are getting higher and higher. come higher. [0003] Pests and diseases are one of the important factors affecting the quality of tea. At present, the key to solve the cultivation technology of pollution-free tea is to control the pests and diseases of tea, improve the disease resistance of tea, reduce the application of chemical pesticides, and ensure the low residual rate of toxic pesticides. The prevention and control of tea plant diseases ...
