Abstract

The invention relates to the technical field of pesticide preparations and specifically relates to a pleocidin synergistic water emulsion and a preparation method thereof. The water emulsion is prepared from the following raw materials in parts by weight: 1-15 parts of pleocidin, 10-25 parts of capsule shell material, 10-15 parts of organic solvent, 3-7 parts of emulsifying agent, 1-5 parts of synergist, 0.5-2.5 parts of wetting dispersant, 1-3 parts of surfactant, 1-3 parts of thickening agent, 2-4 parts of anti-freezing agent, 3-5 parts of penetrant, 0.3-0.7 part of defoaming agent and 50-70parts of deionized water. The pleocidin synergistic water emulsion disclosed by the invention is good in fast-acting property, efficient in dispersion, stable and durable in pesticide effect, long instorage validity, capable of reducing the consumption of a poisonous and harmful solvent, environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a spinosad synergistic aqueous emulsion and a preparation method thereof. Background technique [0002] Spinosad is a macrolide biopesticide, which has rapid contact and stomach poisoning effects on pests, but has no systemic effect, and has a strong penetration effect on leaves, which can kill pests under the epidermis. It is long and has a certain ovicidal effect on some pests. It can effectively control Lepidoptera, Diptera and Thysanoptera pests, and it can also prevent certain pests that eat a lot of leaves in Coleoptera and Orthoptera. , but less effective against piercing-sucking pests and mites. Spinosad is relatively safe to predatory natural enemy insects, and has no cross-resistance with commonly used insecticides. The composition containing spinosyn, that is, its compound preparation, expands the insecticidal spectrum and has a synergistic effect, red...
