Abamectin emulsifiable concentrate preparation and preparation method and use method thereof

Abstract

The invention discloses an abamectin emulsifiable concentrate preparation which is prepared from the following components: abamectin technical, isopropanol, butylated hydroxytoluene, calcium dodecylbenzene sulfonate, styrylphenol polyoxyethylene ether and the balance of N-methyl pyrrolidone. The preparation method comprises the following steps of (1) adding isopropanol and N-methyl pyrrolidone into a preparation tank, and stirring, (2) adding the abamectin technical and an antioxidant into the preparation tank, and stirring, and (3) finally, continuously adding calcium dodecyl benzene sulfonate and styrylphenol polyoxyethylene ether into the preparation tank, and stirring to obtain the abamectin emulsifiable concentrate preparation. The abamectin emulsifiable concentrate preparation prepared by the invention is a faint yellow transparent liquid in appearance, the PH value is 5-6, the emulsion stability is qualified, and the control effect is remarkable; compared with common emulsifiable, the use of benzene is reduced, and the harm to the environment is reduced; the absorption speed in the tree is high, and the effective service life is long.

Description

technical field [0001] The invention belongs to the technical field of tree insect control, and specifically relates to an abamectin emulsifiable concentrate preparation and a preparation method and a use method thereof. Background technique [0002] Nematode disease, also known as tree wilt disease, is a destructive epidemic disease of trees, and the monochamus is its main vector insect. Nematodes develop from eggs to adults, which go through the 4th instar larval stage. The larvae hatched from the eggs shed their skin once inside the eggs, and the hatched larvae are 2nd instar larvae. Every spring, when the vector insect Monochamus alternata is about to emerge, the dispersive 3rd instar molts and forms dispersive 4th instar, i.e. dormant larvae (durable larvae). The larvae at this stage, that is, the 3rd and 4th instar larvae of the dispersed type, are different from those in the reproductive stage in terms of morphology and biological characteristics, such as thickened ...

AI Technical Summary

Problems solved by technology

[0005] But when present abamectin is used as the insecticide of nematode, need to add a large amount of benzene organic matter, bigger impact on the environment, and commonly used avermectin formulation preparation is weaker to nematode killing ability, nematode The control effect is poor
