Chlorfluazuron-containing pesticide suspending agent and preparation method thereof

Abstract

The invention discloses a chlorfluazuron-containing pesticide suspending agent and a preparation method thereof. The chlorfluazuron-containing pesticide suspending agent comprises: by weight, 0.1 to 40% of an active component A, 0.1 to 40% of an active component B, 2 to 10% of one or more dispersants, 1 to 5% of one or more wetting agents, 1 to 8% of one or more functional auxiliary agents, 0.1 to 4% of one or more thickening agents, 1 to 5% of one or more antifreezing agents, 0 to 1% of one or more antiseptics, 0 to 0.8% of one or more antifoaming agents, 0 to 4% of one or more PH conditioning agents, 0 to 2% of one or more anti-oxidants and 10 to 80% of water. The active component A is chlorfluazuron. The active component B is indoxacarb, tebufenozide, acetamiprid, high-efficiency cyhalothrin, thiamethoxam or butene-fipronil. Compared with the traditional pesticide powder, the chlorfluazuron-containing pesticide suspending agent has better drug effects which are the same as drug effects of missible oil, avoids a large amount of a harmful solvent used in missible oil, and has a small average particle size, a high suspension rate, stable performances and a low water separation amount at a normal temperature in two years.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a suspension of a pesticide composition containing chlorfluazuron and a preparation method thereof. Background technique [0002] Chlorfluazuron, also known as difenuron, impatabo, and flufenuron, is a benzoylurea insecticide developed by Ishihara, Japan. The mechanism of action of chlorfluazuron is to inhibit the synthesis of chitin, hinder the normal peeling of insects, cause egg hatching, larval peeling and pupae development deformity, adult eclosion is hindered, it has stomach poisoning and contact killing effects, high efficacy, and slow action speed. It can effectively control pests such as Lepidoptera, Orthoptera, Coleoptera, Hymenoptera, Diptera, etc. in vegetables, cotton, soybeans, corn, fruit trees, potatoes, tea, tobacco leaves, forests, public health, etc., but for aphids , leafhoppers, and planthoppers are ineffective, and are safe to many...

Problems solved by technology

However, the suspending agent is a thermodynamically unstable system. Over time, changes such as bottoming, water separation, and stratification will inevitably occur in the end.
