Problems solved by technology

It has good control effect on rice stem borer, three stem borer and large borer, and can also control leaf roller. In the mid-1970s, the control of rice borer in my country has been using cartap and its intermediates dimehypo and monosultap , resulting in a large-scale occurrence of resistance to
[0004] Profenofos (chemical name: O-(4-bromo-2-chlorophenyl)-O-ethyl-S-propyl phosphorothioate, English common name: profenophos) is an asymmetric organophosphorus insecticide, It has contact and stomach poisoning effects, wide insecticidal spectrum, strong knockdown power, high toxicity, especially highly toxic to birds and fish, and it is unfavorable to use in large doses
[0005] The synergistic combination of pesticides is an effective measure to expand the control spectrum and improve the control effect. So far, there has been no report on the microemulsion combination of cartap + profenofos

Abstract

A composite insecticide in the form of micro-emulsion for agricultural crops is prepared from cartap and profenophos through diluting cartap with clean water, mixing it with phenylacetaldehyde polyoxyvinylether and toluene, adding the emulsified oil of profenophos, and stirring.

Description

technical field [0001] The invention relates to a preparation method of crop insecticide, in particular to a preparation method of cartap+profenofos 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...
