Abstract

The invention discloses a biological insecticide for preventing and treating lepidoptera pests. The biological insecticide is characterized by comprising, by weight, 20-30 parts of castor-oil plants, 20-30 parts of Russian knapweed, 10-15 parts of cablin patchouli herbs, 10-15 parts of artemisia annua, 10-15 parts of neem seeds, 4-8 parts of bacillus thuringiensis powder, 2-4 parts of green muscardine fungus powder, 70-80 parts of carriers, 5-12 parts of wetting agents and 2-5 parts of dispersing agents. The biological insecticide has the advantages that the plant raw materials and microbial raw materials of the insecticide are compounded in use to achieve complementary advantages, and the insecticide is wide in insecticidal spectrum, remarkable in insecticidal effect, free from residues and chemical resistance, green and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of biological pesticide compound insecticides, and in particular relates to a biological insecticide for preventing and controlling lepidopteran pests and a preparation method thereof. Background technique [0002] Lepidoptera pests, represented by cabbage caterpillar, cut moth, cabbage borer, diamondback moth, beet armyworm, spodoptera litura and armyworm, are important pests of vegetables in most areas of my country. These pests affect the normal growth of vegetables by eating the leaves of plants, and can also seriously affect the quality and market value of vegetables by boring. At present, the main means of controlling Lepidoptera pests is the use of chemical pesticides, such as: phoxim, pyridalyl and acetamiprid, etc. The frequent use of chemical pesticides has increasingly aggravated the development of resistance of such pests and increased the cost of pest control It also leads to serious food and environment...
