preparation example Construction

[0031] The present invention has no special limitation on the preparation method of the biological insecticide, and the preparation method of the insecticide well-known to those skilled in the art can be adopted. In the specific implementation process of the present invention, the active ingredients pyrethrin, d-limonene The biopesticide is prepared by conventional mixing with solvents and auxiliary materials.

[0032]The present invention also provides the application of the biopesticide described in the above technical solution in the prevention and control of economic crop pests. In the present invention, the economic crops are preferably tea trees and vegetables; the pests preferably include one or more of green leafhoppers, whiteflies black thorns, whiteflies, aphids and cabbage caterpillars causing crop pests.

[0033] In the present invention, the application rate of the biopesticide is 5-500g / hm based on the total mass of pyrethrins and d-limonene 2 , more preferably ...

Embodiment 1

[0036] 36% pyrethrin·d-limonene soluble liquid

[0037] The mass fraction ratio of each raw material is as follows: 30% of pyrethrin, 6% of d-limonene, 10% of phosphate compound emulsifier, 10% of ethanol, 4% of ethylene glycol, 0.3% of silicone defoamer and the remaining water . During operation, add the original medicine, ethylene glycol, defoamer and water into the reaction kettle, heat and stir to dissolve for 30 minutes, then add emulsifier and stir for 30 minutes, and let it stand for 2 hours to obtain 50% pyrethrin·d-limonene soluble liquid .

Embodiment 2

[0039] 8% Pyrethrin·d-Limonene Soluble Liquid

[0040] The mass fraction ratio of each raw material is as follows: 2% pyrethrin, 6% d-limonene, 10% phosphate compound emulsifier, 4% ethylene glycol, 0.3% organic silicon defoamer and supplemented with water. During operation, add the original medicine, ethylene glycol, defoamer and water into the reaction kettle, heat and stir to dissolve for 30 minutes, then add emulsifier and stir for 30 minutes, and let it stand for 2 hours to obtain 10% pyrethrin·d-limonene soluble liquid .

Abstract

The invention provides a biological insecticide, belonging to the technical field of crop pest control. The biological insecticide is prepared from pyrethrin, d-limonene and insecticide acceptable adjuvants; the total mass percent content of the pyrethrin and the d-limonene in the biological insecticide is 0.01-90%; the mass ratio of the pyrethrin to the d-limonene is equal to 1 to (0.1-10). The biological insecticide is safe and non-toxic, high in insecticidal synergistic effect and good in insecticidal effect, and has a good prevention and control effect on crop pests such as empoasca flavescens, aleurocanthus spiniferus quaintance, bemisia tabaci, aphid and cabbage caterpillar.

Description

technical field [0001] The invention belongs to the technical field of biopesticides, in particular to a biopesticide and its application. Background technique [0002] Green leafhopper, whitefly blackthorn, whitefly, aphids, cabbage caterpillar, etc. are the main pests on commercial crops. At present, the main pesticides for controlling such pests are lambda-cyhalothrin, buprofezin, imidacloprid, butyl Chemical pesticides such as ether urea, bifenthrin, and pymetrozine. Although chemical pesticides have made great contributions to agricultural production, they are highly toxic and remain in plants, and will penetrate into soil, rivers, and groundwater, affecting people's health, reducing soil quality, and causing environmental pollution . [0003] As people pay more and more attention to the environment and health, my country's agricultural production is changing from quantity to quality and safety. The planting area of ​​organic tea, organic vegetables and other crops is...
