Compound imidacloprid aqueous suspension prepared by using tea saponin as synergist and surface active agent

Abstract

The invention discloses a compound imidacloprid aqueous suspension prepared by using tea saponin as a synergist and a surface active agent. In the aqueous suspension, an effective mass ratio of the imidacloprid to the tea saponin is 100:5-30, preferably 100:10. The aqueous suspension has the advantages of fully utilizing the action of the tea saponin as an environment-friendly type organic pesticide adjuvant, being easily degraded under natural conditions, avoiding causing pollution on the environment, being nonpoisonous for people and animals, saving production cost, producing an synergisticaction for pesticides, having actual application values on development of novel formulations of the imidacloprid and prevention and control of pests, facilitating industrial comprehensive utilizationof oil-tea cake resources, and creating a novel application path for the tea saponin.

Description

Technical field The present invention relates to the technical field of pesticides, in particular to a compound imidacloprid water suspension agent for efficiently preventing and controlling piercing and sucking pests such as aphids. Background technique Tea saponin (TS), also known as tea saponin or tea saponin, is a by-product of oil extraction from the seeds of Camelliaoleifera, C.sinensis and other Camellia (Theacease) and Camellia (Camellia) plants. The extract of meal is a pentacyclic triterpenoid. As a non-ionic surfactant, tea saponin has the properties of emulsifying, dispersing, wetting, foaming, etc. It can be used to produce emulsifiers, detergents, foaming agents, preservatives, pesticides and pharmaceutical products, and can be used in Pesticides, medicines, pesticides, daily chemicals, textiles, papermaking, building materials, mineral processing, food industry and medicine industries and fields. Natural additives such as tea saponin or tea cumin and saponins c...
