A kind of ethiprole dipropiprene oil suspension concentrate and its preparation method and application

Abstract

The invention provides an ethiprole·diproteril oil suspension, a preparation method and application thereof, and relates to the technical field of pesticides. Ethpronil·diproteril oil suspension concentrate is composed of the following components according to the weight percentage: ethiprole 5‑20%, aproteril 2%-20%, tertiary butyl hydroquinone 1%-3%, surfactant 5%-25%, thickener 0.1-10%, solvent to make up the weight to 100%. The preparation method of the oil suspension comprises the following steps: first mixing ethiprole and dipropacyclopyrene, tertiary butyl hydroquinone, surfactant, thickener and solvent, sanding and filtering Obtain ethiprole·dipropiprene oil suspension concentrate. Due to the ingenious formula of the oil suspension of the present invention, the technical problem that ethiprole and diproteril are easy to decompose is overcome, the stability is significantly enhanced, the defect of excessive drug loss during application is avoided, and the number of application is reduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an ethiprole-diaproteril oil suspension, a preparation method and application thereof. Background technique [0002] Ethpronil is an arylpyrazole insecticide that can control sweet potato whitefly and scale insects. It has high efficiency, low dosage, long-lasting effect, safety to crops, low toxicity to fish, and little impact on the ecological environment. features. It can be used to control pests of Homoptera, Thysanoptera, Diptera and Lepidoptera. Its inhibitory effect on insects is manifested in affecting the molt and reproduction of insects. For the sanitary pests of mosquitoes and flies, the use of low doses of this product in the late 4th instar larvae will lead to the death of the pupation stage and inhibit the formation of adults. Also has systemic transfer activity, affecting larvae hiding on the underside of leaves. [0003] Dipropyrene, found in biological fer...
