Biopesticide for preventing and controlling plant diseases and insect pests of paddy and preparation method thereof

Abstract

The invention provides a biopesticide for preventing and controlling plant diseases and insect pests of paddy and belongs to the technical field of pesticides. The biopesticide for preventing and controlling plant diseases and insect pests of paddy is prepared from the following raw materials in parts by weight: 0.1-0.5 part of avermectins, 0.5-3 parts of bamboo vinegar, 1-5 parts of chitosan and 5-20 parts of traditional Chinese medicine compound, wherein the traditional Chinese medicine compound is prepared from the following raw materials in parts by weight: 10-30 parts of aglaia odorata lour, 10-30 parts of coptis chinensis, 5-20 parts of needle juniper, 5-20 parts of pilea longicaulis, 5-20 parts of rhododendron glanduliferum, 5-15 parts of inula flower, 3-12 parts of vernonia anthelmintica, 3-12 parts of elm bark and 3-12 parts of acorus calamus. According to the invention, the avermectins, the bamboo vinegar, the chitosan and the traditional Chinese medicine compound are scientifically mixed and have a synergistic effect, so that the anti-microbial and insect-killing capacities of the acquired biopesticide are obviously enhanced, the preventing and controlling scope is widened, the phytotoxicity occurrence rate is reduced, the efficiency is high and the labor and time are saved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a biological pesticide for preventing and controlling rice diseases and insect pests and a preparation method thereof. Background technique [0002] China is the first country in the world to grow rice and produce the most rice. Rice has the highest average yield per unit area among various food crops. my country's rice planting areas are mainly in the south, and in recent years there has been a trend of gradually concentrating in the middle and lower reaches of the Yangtze River and Heilongjiang rice producing areas and other advantageous areas. Rice is vulnerable to pests and diseases in the production process, and there are many types of pests and diseases, so the amount of pesticide application remains high. Statistics show that the amount of pesticides used in rice production accounts for about 15% of China's total pesticide consumption. [0003] Rice is vul...

Problems solved by technology

At the same time, while biopesticides continue to develop, there are also some outstanding problems and difficulties that plague their development, such as slow knockdown speed of biopesticides, short validity period, relatively narrow insecticidal spectrum, and short-term control of pest populations. The power is not strong, and it cannot quickly reduce the population density of pests, etc.
