Problems solved by technology

[0002] In recent years, although great progress has been made in the research and development of botanical pesticides in my country, there are still some problems on the whole, mainly in: high cost, slow action, short duration of field effect, and repeated application Or mixed with other synthetic pesticides to achieve the expected prevention and control purposes; drug stability is poor, the control effect of some botanical pesticide preparations is not stable in production and practical application, and is easily affected by environmental factors; there are not many varieties and types of botanical pesticides
[0003] According to the principle of "mutual cooperation and synergistic effect" between Chinese herbal medicines, the present invention provides a method for preparing botanical pesticides that are generally unstable in composition and slow in efficacy

[0024] Compound insecticide: according to the ratio of 1:3:1, wolftoxin-0.2g, marigold-0.6g, rutin-0.2g, humic acid-0.2g, sesamin-0.2g, epoxidized vegetable oil -0.2g, penetrating agent T-8g, Tween 80-8g, the rest is made up to 100g with distilled water, added to a stirring container with a thermometer, heated to 60°C, mixed and stirred evenly, and the active ingredient content of 100g is 1 % botanical pesticides. It was diluted 1000 times before use.

[0025] Wolf’s poison insecticide: take 1g of wolf’s poison active substance, humic acid-0.2g, sesamin-0.2g, epoxidized vegetable oil-0.2g, penetrant T-8g, Tween 80-8g, and the rest are replenished with distilled water 100g is added into a stirring container with a thermometer, heated to 60°C, mixed and stirred evenly to obtain 1...

Embodiment 2

[0033] Prepare according to the ratio of 1:7:12, take wolftoxin-0.1g, marigold-0.7g, rutin-1.2g, humic acid-0.2g, sesamin-0.2g, epoxidized vegetable oil-0.2g , Penetrant T-8g, Tween 80-8g, and the rest are made up to 100g with distilled water, put into a stirring container with a thermometer, heated to 60°C, mix and stir evenly, and obtain 100g of 2% botanical compound insecticide agent.

[0034] Dilute 2% plant insecticide 1000 times to prepare 2mg / L liquid medicine. Measure the toxicity to Plutella xylostella larvae with leaf residue method, indoor test result shows, the insecticidal effect to 3 instar Plutella xylostella larvae is 97.2% (24 hours) and 98.7% (48 hours), to 4 instar Plutella xylostella larvae The insecticidal effects were 90.3% (24 hours) and 95.1% (48 hours). Spray outdoors to prevent and control spider mite on greenhouse vegetables, and the control effects are 79.2% (the 3rd day after the drug), 87.7% (the 5th day after the drug), and 93.1% (the 7th day a...

Embodiment 3

[0036] According to the ratio of 1:5:14, take wolftoxin-0.1g, marigold-0.5g, rutin-1.4g, humic acid-0.2g, sesamin-0.2g, epoxidized vegetable oil-0.2g, Penetrant T-8g, Tween 80-8g, make up to 100g with distilled water, add to a stirring container with a thermometer, heat to 60°C, mix and stir evenly to obtain 100g of 2% compound insecticide.

[0037]2% plant insecticide is diluted 1000 times, is mixed with the liquid medicine of 2mg / L, measures the toxicity to diamondback moth larvae with leaf residue method, and indoor test result shows, the insecticidal effect to 3rd instar diamondback moth larvae is 96.4% (24 hours) and 97% (48 hours), and the insecticidal effect on 4th instar diamondback moth larvae is 98.1% (24 hours) and 94.7% (48 hours). Spray outdoors to prevent red spider mite on vegetables in the greenhouse. The control effects are 78.1% (the 3rd day after the medicine), 90.3% (the 5th day after the medicine), and 92.2% (the 7th day after the medicine).
