Microbial pesticide and preparation method thereof

Abstract

The invention discloses microbial pesticide and a preparation method thereof. The microbial pesticide is prepared from the following raw materials in parts by weight: 7 to 9 parts of metarhizium anisopliae, 10 to 20 parts of baicalein, 6 to 8 parts of lactobacillus acidophilus, 7 to 9 parts of peat immobilized enzymes, 10 to 12 parts of paenibacillus polymyxa, 10 to 20 parts of chloranthus serratus roots, 15 to 25 parts of sugarcane peel and 5 to 7 parts of tobacco stems and roots. The prepared pesticide has the broad-spectrum effects of preventing and treating crop diseases, and has the special effect on tomato late blight, chili late blight and cabbage wilt diseases. The product quality is stable; the product is efficient, nontoxic and is safe for human bodies; no pollution exits; the ecological environment is protected; the microbial pesticide can replace chemical pesticide for agricultural production; the development requirements of green agriculture are met.

Description

technical field [0001] The invention relates to the field of crop disease and insect pest prevention, in particular to a microbial pesticide and a preparation method thereof. Background technique [0002] Crop diseases and insect pests are one of the main reasons for the reduction of crop production. Severe diseases and insect pests can lead to a large reduction in production, or even no harvest. According to the investigation of the Food and Agriculture Organization of the United Nations, 20% to 40% of the grain harvests are taken away by diseases and insect pests in the world every year, and the resulting economic losses amount to 120 billion US dollars. Therefore, pesticides play an important role in the agricultural production process. At present, the annual production of pesticides at home and abroad is more than 2 million tons, and chemical pesticides occupy an absolute dominant position. However, the harmful consequences of chemical pesticides causing environmental p...

Problems solved by technology

At present, the annual production of pesticides at home and abroad is more than 2 million tons, and chemical pesticides occupy an absolute dominant position. However, the adverse consequences of chemical pesticides causing environmental pollution, ecological imbalance, teratogenicity, carcinogenicity, poisoning and death are becoming more and more prominent.
