Embodiment 1

[0043] Example 1: 21% pirimicarb·clothianidin wettable powder

[0044] 1% pirimicarb, 20% clothianidin, 5% fatty acid polyoxyethylene ester, 5% sodium lauryl sulfate, kaolin to make up to 100%, after mixing, stir evenly in a stirring tank, and then pass through a jet mill Pulverize to obtain 21% pirimicarb·clothianidin wettable powder.

Embodiment 2

[0045] Example 2: 70% pirimicarb·clothianidin wettable powder

[0046] 40% of pirimicarb, 30% of clothianidin, 7% of lignosulfonate, 5% of saponin powder, and bentonite are added to 100%. After mixing, they are uniformly stirred in a stirring tank, and then pulverized by a jet mill to prepare A 70% WP of pirimicarb clothianidin was obtained.

Abstract

The invention discloses an insecticidal composition containing clothianidin and pirimicarb, the weight ratio of the active component clothianidin to the active component pirimicarb is 1-30:1-40, the total active components account for 1%-70% by weight of the composition, and the forms of the insecticidal composition comprise wettable powders, water-soluble granules, suspending agents, emulsions in water and microcapsule suspending agents. The insecticidal composition is based on dual function mechanism of two insecticides such as clothianidin and pirimicarb, has the two characteristics of being quick-acting and long-acting, so that the insecticidal composition is increased in application scope, enlarged in insecticidal spectrum, not only can control leafhopper, but also has substantial control effect on cotton aphid, is obvious in synergy, causes no contradiction, and is long in lasting effect, reduced in drug applying frequency and reduced in drug applying cost.

Description

technical field [0001] The invention relates to an insecticidal composition with clothianidin and pirimicarb as active ingredients. Background technique [0002] Clothianidin, whose chemical name is (E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-2-nitroguanidine, is produced by Bayer and Japan Takeda and Takeda jointly conduct global market development. [0003] Its structural formula is: [0004] [0005] Clothianidin is a class of highly efficient, safe and highly selective neonicotinoid insecticides. Its action is similar to that of nicotinic acetylcholine receptors, and it has contact killing, stomach poisoning and systemic activity. It is mainly used as an insecticide for preventing and controlling aphids, leafhoppers, thrips, planthoppers and other pests of Hemiptera, Coleoptera, Diptera and some Lepidoptera on rice, vegetables, fruit trees and other crops. It has the advantages of broad spectrum, less dosage, low toxicity, long duration of drug effect, no ha...
