example 1

[0013] Use 0.5Kg concentration of 90% insecticidal cyclocyclone and add 0.5Kg of clear water to make a 35% insecticidal cyclocyclam solution, add 1 gram of phenylacetaldehyde polyoxyethylene ether anionic emulsifier, add 0.3Kg solvent oil, and stir for 20 minutes- After 30 minutes, add 0.2 kg of 5% fipronil suspending agent, stir well and mix evenly to obtain the combined microemulsion of the present invention.

Embodiment 2

[0015] Add 0.7Kg of clear water to make 18.5% insecticidal cyclocyclone solution with 0.3Kg concentration of 90% insecticidal cyclocyclone, add 1.2 grams of phenylacetaldehyde polyoxyethylene ether anionic emulsifier, add 0.3Kg solvent naphtha, and stir for 25 minutes- After 40 minutes, add 0.3 kg of 5% fipronil suspending agent, stir well and mix evenly to obtain the combined microemulsion of the present invention.

[0016] Implementation three

[0017] Be 90% cartap with 0.6Kg concentration and add clear water 0.4Kg to be made into 0.47% insecticidal ring solution, add phenylacetaldehyde polyoxyethylene ether anionic emulsifier 2 grams, add 0.4Kg solvent naphtha again, stir for 35 minutes- After 60 minutes, add 0.25 kg of 5% fipronil suspending agent, stir well and mix evenly to obtain the combined microemulsion of the present invention.

Abstract

The invention relates to a method for preparing crop combined insecticide micellar emulsion from thiocyclam and fipronil. The method comprises diluting 90% thiocyclam with clean water to 20-50%, mixing the diluted thiocyclam with anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether, solvent naphtha and 5% fipronil suspension at a wt. ratio of 1:0.0005-0.002:0.02-0.5:0.1-0.3, and stirring. The invention has improved thiocyclam utilization ratio and effect due to the use of anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether which increases the adhesion and permeability of micellar emulsion on crop, and use of fipronil suspension which increases kills knockdown force to pest and reduces fastness of pest against thiocyclam.

Description

technical field [0001] The invention relates to a preparation method of an insecticide for crops, in particular to a preparation method of a combined microemulsion of insecticidal cyclocyclone and fipronil. Background technique [0002] Borers are major pests of rice and belong to the order Phosphoptera. In the rice area, there are mainly three kinds of rice stem borers, rice stem borers and leaf rollers, which occur to varying degrees in various regions of the country. [0003] Insecticidal cycle (chemical name: N,N-dimethyl-1,2,3-trithiahex-5-amine, English common name: thiocyclam) nereistoxin insecticide, with contact and stomach poisoning, It has a certain systemic conduction effect and has ovicidal properties. This product has a slow effect on pests and a short residual effect period, and has a good control effect on Lepidoptera and Coleoptera. [0004] Fipronil (chemical name: 5-amino-3-cyano-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoromethylsulfinylpyrazole...
