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.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a botanical pesticide for preventing and controlling tea plant diseases and insect pests and a preparation method thereof. Background technique [0002] my country has a vast territory, spanning the tropics, subtropics, and warm temperate zones from north to south, and is the origin of tea trees in the world. Tea trees have strong adaptability and can grow in both high mountains and plains. However, there are many kinds of tea tree diseases and insect pests, and the flora is complex, which seriously affects the production of tea. There are many types of tea tree pests and diseases, according to statistics. There are more than 30 common diseases of tea trees recorded, and more than 40 pests. Most of the pathogens that cause tea tree diseases are fungi, in addition to bacteria, mycoplasma, nematodes, algae and parasitic seed plants, etc. Most of the tea tree pests ...

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, including the low activity of some botanical pesticides, large dosage, weak knockdown power, and slow efficacy, which is not conducive to the development of sudden epidemic diseases and insect pests. Prevention and control; the type and content of active ingredients are affected by their own genetic factors and external environmental conditions such as soil, temperature, light, and soil value, and will have regional and seasonal changes; and the content of active ingredients in different parts of the plant is also different , especially some active ingredients are unstable to light and heat etc.
