Abstract

The invention relates to a method for preparing the thiocyclam hydroxalate-imidacloprid composite wettable powder of a crop pesticide. The wettable powder mainly comprises thiocyclam hydroxalate 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 proportion of 10:2.5:1; and the mixture is mixed with an amount of 90 percent thiocyclam hydroxalate through air flow. Moreover, the mixture ratio of 95 percent imidacloprid, 90 percent thiocyclam hydroxalate and the composite auxiliary agent is 1:12-18:19-12.2.

Description

technical field [0001] The invention relates to a method for preparing an insecticide for crops, in particular to a method for preparing a wettable powder composed of insecticidal cyclocyclam+imidacloprid. 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] Insecticidal cycle (chemical name: N,N-dimethyl-1,2,3-trithia-5-amine, common name in English: thiocyclam) nereistoxin insecticide, has contact killing and stomach poisoning effects, has Certain systemic 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), nicoti...
