Abstract

The invention discloses plant essential oil for repelling tea lesser leafhoppers and a preparation method thereof, and belongs to the technical field of green prevention and control of tea garden pests. The plant essential oil for repelling tea lesser leafhopper is prepared by mixing, by weight, 20-80 parts of chestnut flowers, 10-60 parts of azadirachta indica leaves and 10-60 parts of walnut leaves and then carrying out distilling and extracting. The plant essential oil extracted from plants can be used for repelling, preventing and treating tea lesser leafhoppers in tea gardens, and has the advantages of being environmentally friendly, convenient to use, not prone to generating drug resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of green prevention and control of tea garden pests, and in particular relates to a plant essential oil for repelling tea leafhoppers and a preparation method thereof. Background technique [0002] Tea green leafhopper (tea green leafhopper) belongs to the Hemiptera (Hemiptera) leafhopper (Cicadellidae), is one of the major pests of tea trees in my country, widely distributed in major tea areas across the country. Over the years, tea leafhoppers have mainly relied on chemical pesticides for control, causing pests to develop resistance to some pesticides, resulting in reduced control effects, and excessive application will lead to many problems such as excessive pesticide residues. In order to avoid environmental pollution and excessive pesticide residues in tea, and ensure the safety and sustainable development of tea production, it is very important to develop green prevention and control measures based on ...
