example 1

[0013] Use 0.5Kg concentration of 95% cartap and add 0.5Kg of clear water to make 45% cartap solution, add 1 gram of phenylacetaldehyde polyoxyethylene ether anionic emulsifier, add 0.3Kg toluene, and stir for 5 minutes-10 Minutes later, add 0.2 kg of 5% fipronil suspending agent, fully stir and mix evenly to obtain the combined microemulsion of the present invention.

Embodiment 2

[0015] Use 0.3Kg concentration of 95% cartap and add 0.7Kg of clear water to make 28.5% cartap solution, add 1.2 grams of phenylacetaldehyde polyoxyethylene ether anionic emulsifier, add 0.3Kg toluene, stir for 5 minutes-10 Minutes later, add 0.3 kg of 5% fipronil suspending agent, fully stir and mix evenly to obtain the combined microemulsion of the present invention.

[0016] Implementation three

[0017] Use 0.6Kg concentration of 95% cartap and add 0.4Kg of clear water to make 0.57% cartap solution, add 2 grams of phenylacetaldehyde polyoxyethylene ether anionic emulsifier, add 0.4Kg toluene, and stir for 5 minutes-10 Minutes later, add 0.25 kg of 5% fipronil suspending agent, fully stir and mix evenly to obtain the combined microemulsion of the present invention.

Abstract

The invention relates to a method for preparing combined crop insecticide micellar emulsion from cartap and fipronil. The method comprises diluting 98% cartap with clean water to 30-60%, mixing the diluted cartap with anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether, toluene as solvent 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 cartap utilization ratio and effect due to the use of anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether which increases the afhesion and permeability of micellar emulsion on crop, and use of fipronil suspension which increases kill knockdown force to pest and reduces fastness of pest against cartap.

Description

technical field [0001] The invention relates to a preparation method of crop insecticide, in particular to a preparation method of cartap+fipronil combined microemulsion. 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] Cartap (chemical name: 1,3-bis(carbamoylthio)-2-dimethylaminopropane, English common name: cartap) nereistoxin insecticide has contact and stomach poisoning effects, it invades The junction of nerve cells blocks the transmission of acetylcholine secreted by the former nerve cell to the latter nerve cell, so that the nerve cells do not excite, paralyzes the nerves of insects, cannot eat, cannot act, stops development, and even dies. It has good control effect on rice stem borer, three stem borer and large borer, and can also control l...
