Problems solved by technology

[0004] Insecticide varieties containing a single component often have defects in the control of pesticide pests: continuous use is easy to produce resistance, narrow insecticidal spectrum, cannot provide comprehensive protection for crops, and the cost of pesticides for farmers is high.
[0005] At present, the conventional dosage forms of lambda-cyhalothrin and emamectin benzoate are mainly emulsifiable concentrates, which contain a large amount of organic solvents, which have potential safety hazards in production, and will cause serious harm to the environment in field use

Abstract

The invention discloses a composite insecticidal and acaricidal nano aqueous agent containing lambda-cyhalothrin and emamectin benzoate, wherein the composite insecticidal and acaricidal nano aqueousagent is prepared from lambda-cyhalothrin and emamectin benzoate as active ingredients, a surfactant and water, lambda-cyhalothrin and emamectin benzoate accounts for 3-50 wt%, the surfactant accountsfor 5-20 wt%, the balance of the water, and a weight ratio of the lambda-cyhalothrin to the emamectin benzoate is (20:1)-(1:20). According to the invention, nanoscale micelles formed by the surfactant bear lambda-cyhalothrin and emamectin benzoate insoluble in water, wherein the effective components exist in the nano aqueous agent in the form of nanoscale particles, so that the nano aqueous agentis beneficial to attachment, spreading and permeation of the nano aqueous agent on a target so as to resist rain wash; and the two effective components can generate a synergistic effect, so that lepidoptera pests and mite pests on crops can be prevented and treated, the insecticidal speed is high, the lasting period is long, and the prevention and control effect is obviously higher than that theprevention and control effect of a single agent.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to an insecticidal and mite-killing nano water agent with beta-cyhalothrin and emamectin benzoate as main active ingredients and its application. Background technique [0002] Lambda-cyhalothrin, molecular formula: C 23 h 19 CIF 3 NO 3 . Chemical name: α-cyano-3-phenoxybenzyl 3-(2-chloro-3,3,3-trifluoropropenyl)-2,2-dimethylcyclopropanecarboxylate. It is a high-efficiency, broad-spectrum, quick-acting pyrethroid insecticide and acaricide. It mainly has contact and stomach poisoning effects, and has no systemic effect. It has a good effect on various pests such as Lepidoptera, Coleoptera and Hemiptera and other pests, as well as spider mites, rust mites, gall mites, etc. It can also control when insects and mites coexist, and can control cotton bollworm and cotton boll worm, cabbage caterpillar, cabbage tube aphid, tea geometrid, tea caterpillar, tea orange gall mite, leaf gall mite, ci...
