Abstract

The invention relates to a preparation method for a plant pesticide. The preparation method comprises the following steps of cutting 15.4-26.6 parts of garlic into small granules, turning the small garlic granules over in air for 15-20 minutes, adding 6.8-9.9 parts of edible alcohol, and grinding the mixture into mashed alcohol garlic; cutting 29.4-39.7 parts of onions into small blocks, grinding the small onion blocks into slurry, and uniformly mixing the onion slurry and the mashed alcohol garlic; crushing 2.4-4.6 parts of rheum officinale, extracting the rheum officinale in water for 2-5 hours, and filtering slag to obtain an extracting solution; adding the extracting solution into the onion garlic alcohol slurry for uniform stirring, standing the mixture for 15-20 days, and filtering slag to obtain the plant pesticides. According to the preparation method, edible plants are used as the raw materials, so that the plant pesticide integrates disease and insect prevention and control and plant nutrition supplementation and is pollution-free, residue-free and high in efficiency; the using amount of the plant pesticide is small, and the withdrawal time is not needed.

Description

[0001] Technical field: [0002] The invention relates to a preparation method of botanical pesticides. [0003] Background technique: [0004] Chemical pesticides are widely used to control crop diseases and insect pests quickly. However, its high residue is harmful to the human body and destructive to the environment. Due to the gradual resistance of harmful organisms to chemical pesticides, the use of pesticides has increased year by year. The average amount per mu is 8-10 kg, and the maximum amount exceeds 15 kg. It seriously pollutes the soil, water, damages the ecological environment, and causes human and animal enrichment through the food chain. Chronic poisoning, endangering human health and life safety. At the same time, chemical pesticides also reduce the quality and flavor of crops. Although the country has invested heavily in the construction of pollution-free vegetable bases, it is still inevitable to use a large amount of chemical pesticides in the actual p...
