Botanical pesticide for preventing and treating diseases and insect pests of tea trees

Abstract

The invention provides a botanical pesticide for preventing and treating diseases and insect pests of tea trees, belonging to the technical field of pesticides. The botanical pesticide is prepared from the following raw materials in parts by weight: 10-30 parts of Chinese honeylocust fruit, 10-30 parts of rhizoma arisaematis, 10-30 parts of manyleaf paris rhizome, 10-30 parts of syringa oblate, 5-20 parts of cassia bark, 5-20 parts of dianthus caryophyllus, 5-20 parts of cortex magnoliae officinalis, 5-15 parts of holy basil, 3-12 parts of cacumen platycladi, 3-12 parts of rhizoma pinelliae, 3-12 parts of banana root and 1-10 parts of liquorice. By virtue of scientific compounding of Chinese herbal medicines, a synergistic interaction effect is achieved, the anti-microbial and insecticidal capacities of the pesticide are remarkably enhanced, the anti-microbial and insecticidal spectra are relatively wide, and the possibility of generating drug resistances of pests is low.

Problems solved by technology

In the 21st century, people have higher and higher requirements for pollution-free food and green food, especially the quality and safety requirements of tea are almost "harsh". The control of chemical pesticides is an effective measure, but large-scale application will lead to environmental pollution, excessive pesticide residues, increased resistance of pests, and increased agricultural costs, etc. A series of problems that affect the sustainable development of tea

However, the development and utilization of botanical pesticides is still very slow, and there are many limiting factors, inclu
