Embodiment 1

[0013] The present invention is a biological pesticide, which is made of the following raw materials in parts by weight: 0.5 parts of polyoxin, 1 part of ascorbic acid, 5 parts of ethanol, 2 parts of polyoxyethylene ether of phenacetol, 3 parts of ethyl acetate, 10 parts of isobutanol, 15 parts of water.

[0014] A kind of production method of above-mentioned biopesticide, comprises the following steps:

[0015] (1) Add polyoxin, ascorbic acid, ethanol and polyoxyethylene phenol ether into the dispersion tank according to the above formula, mix with 1 / 2 of the water phase, and stir at a low speed of 300 rpm for 20 minutes;

[0016] (2) Add ethyl acetate and isobutanol to the slurry formed in step (1) according to the above formula, and stir evenly;

[0017] (3) Finally, add the remaining 1 / 2 water into the slurry, and stir evenly at a speed of 600 rpm.

Embodiment 2

[0019] The present invention is a kind of biological pesticide, which is made of the following raw materials in parts by weight: 2 parts of polyoxin, 3 parts of ascorbic acid, 7 parts of ethanol, 6 parts of polyoxyethylene phenol ether, 5 parts of ethyl acetate, 15 parts of isobutanol, 20 parts of water.

[0020] A kind of production method of above-mentioned biopesticide, comprises the following steps:

[0021] (1) Add polyoxin, ascorbic acid, ethanol and polyoxyethylene phenol ether into the dispersion tank according to the above formula, mix with 1 / 2 of the water, and stir at a low speed of 500 rpm for 30 minutes;

[0022] (2) Add ethyl acetate and isobutanol to the slurry formed in step (1) according to the above formula, and stir evenly;

[0023] (3) Finally, add the remaining 1 / 2 water into the slurry, and stir evenly at a speed of 800 rpm.

Abstract

The invention discloses a biopesticide. The biopesticide is prepared from the following raw materials by weight: 0.5 to 2 parts of polyoxin, 1 to 3 parts of ascorbic acid, 5 to 7 parts of ethanol, 2 to 6 parts of phenylethyl phenol polyoxyethylene ether, 3 to 5 parts of ethyl acetate, 10 to 15 parts of isobutanol and 15 to 20 parts of water. The biopesticide has strong efficacy on injurious insects with pesticide resistance, can maintain the efficacy for 7 to 12 days and has the advantages of no toxicity, no public nuisance, no residual, no pollution, safety to people, livestock and birds, no phytotoxicity, a wide insecticidal spectrum, strong penetration performance and an excellent killing effect on injurious insects like pod borers, scale insects, locusts, illiberis pruni, cabbage caterpillar and plutella xylostella.

Description

technical field [0001] The invention relates to a pesticide and a production method thereof, in particular to a biological pesticide and a preparation method thereof. Background technique [0002] At present, farmers in rural areas are still widely using organophosphorus pesticides. These highly toxic chemical pesticides will not only cause environmental pollution, water quality deterioration, bring a series of disasters to humans and animals, but also directly cause great harm to living things. People who eat food containing highly toxic pesticides will cause acute poisoning, and there are potential hazards of teratogenic, carcinogenic, and mutagenic. Highly toxic pesticides and insecticides can also affect the development of the fetus and cause fetal deformities. Epidemiologists believe that pesticides in food are linked to cancer, cardiovascular disease, diabetes and Parkinson's disease. In addition, the residues of highly toxic chemical pesticides have hindered the exp...
