Problems solved by technology

However, its high residues are harmful to the human body and increasingly 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 state 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 production process

Abstract

The invention relates to a botanical biopesticide. The botanical biopesticide is an aqueous emulsion composed of the extracts of plant active ingredients and auxiliaries, wherein the plant active ingredients include the extracts of sophora alopecuroide, cynanchum komarovii and thymus serpyllum, and the water extracts of onion, garlic and rheum; the auxiliaries include white sugar, turpentine oil and an emulsifying agent. Prepared from the reproducible edible plants used as the raw materials, the botanical biopesticide is pollution-free, has no pollution on the environment, complies with the pollution-free green ecological agricultural input norms and also has no withdrawal time. The botanical biopesticide is prepared compatibly from the Chinese herbal medicines, namely sophora alopecuroide, cynanchum komarovii and thymus serpyllum, added with the garlic as the major ingredient, onion as the auxiliary ingredient and rheum as the initiator; in the formula, the onion, similar to the garlic, contains a plurality of biological sulfides, and the sulfides are combined with the sulfides in the garlic to generate new allicin under the action of the alliinase. As the rheum and table vinegar are added, the efficacy and stability of the botanical biopesticide are further improved and the botanical biopesticide can be preserved for a long time without losing efficacy; the quality of crops can be improved.

Description

technical field [0001] The invention relates to a botanical biopesticide, in particular to a botanical pesticide which uses plant crops as raw materials and is pollution-free and a preparation method thereof. Background technique [0002] 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 vegeta...
