Abstract

The invention relates to a method for preparing the cartap-imidacloprid composite wettable powder of a crop pesticide. The wettable powder mainly comprises cartap and imidacloprid. The method comprises the following steps that: firstly, an amount of a composite auxiliary agent is added in an amount of 95 percent imidacloprid raw pesticide so as to prepare 10 percent wettable powder; the composite auxiliary agent is mixed by light calcium carbonate, white carbon black and sodium alkyl naphthalene sulfonate according to a certain mixture ratio of 10:2.5:1; and the mixture is mixed with an amount of 95 percent cartap through air flow. Moreover, the mixture ratio of 95 percent imidacloprid to 95 percent composite cartap auxiliary agent is 1:12-18:19-12.

Description

technical field [0001] The invention relates to a preparation method of crop insecticide, in particular to a preparation method of cartap+imidacloprid combined wettable powder. Background technique [0002] Borers and planthoppers are the main pests of rice. In the middle and late stages of rice, there are two major pests that occur at the same time. In order to achieve the goal of eradicating pests with one-time use of pesticides, and achieving the purpose of maintaining yield and abundance. [0003] Cartap (chemical name: 1,3-bis(carbamoylthio)-2-dimethylaminopropane, English common name: cartap) nereistoxin insecticide has contact killing and stomach poisoning effects, and has certain internal Absorption conduction and ovicidal properties. This product has a good control effect on Lepidoptera and Coleoptera. [0004] Imidacloprid (chemical name: 1-(6-chloro-3-pyridylmethyl)-N-nitroimidazolidin-2-ylamine, English common name: imidacloprid), nicotinyl chloride insecticid...
