Problems solved by technology

However, the heavy aromatic hydrocarbons or second-line oils used in traditional electrostatic spray formulations not only pollute the environment, but also generate limited charges, which limits the further improvement of the deposition amount of droplets on the target.
[0013] At present, the preparations of etofenprox mainly include suspending agent, emulsion in water, etc., but the electrostatic oil preparation of etofenprox has not been reported yet.

Abstract

The invention relates to an ethofenprox static oiling agent and a preparation method thereof. 2-ethoxyethyl acetate and / or modified carbamic acid ester are / is taken as a solvent; the ethofenprox static oiling agent comprises the following ingredients by weight percentage: 0.5%-30% of ethofenprox, 2%-20% of a cosolvent and the balance of the 2-ethoxyethyl acetate and / or modified carbamic acid esteras the solvent. The electrical conductivity of the static oiling agent provided by the invention is greatly improved, and the deposit rate and the uniformity of fog drops sprayed by the static oilingagent on leaves are obviously improved, so that the utilization rate of a pesticide is obviously improved, and the application amount of the pesticide is reduced; in addition, the static oiling agenthas less pollution to environment, so that the static oiling agent can be practically used for preventing crop pests, and the plant yield is improved.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an etofenprox electrostatic oil agent and a preparation method thereof. Background technique [0002] Ethofenprox has no chrysanthemum acid in its structure, but it is still called a pyrethroid-like insecticide because of its spatial structure and pyrethroids. The advantages of ester pesticides have the characteristics of broad insecticidal spectrum, high insecticidal activity, fast knockdown speed, long residual effect period, and safety to crops. The drug is suitable for rice, vegetables, and cotton, and is used to control pests of Lepidoptera, Hemiptera, Coleoptera, Diptera, Orthoptera, and Isoptera, such as brown lice, white-backed planthopper, and black-tailed leaf Cicadas, cotton bollworms, red bollworms, green peach aphids, melon aphids, whiteflies, cabbage caterpillars, tea caterpillars, tea loopers, tea thorn moths, peach and pear borers, citrus leaf miners, tobacco ...
