Abstract

The invention relates to an agricultural chemical that is a compositional preparation of benzoylureas insecticide and buprofezin having a better ability of preventing insect pests such as aphids, plant hopper, leafhopper, whitefly and the like.The active ingredients of the compositional preparation is prepared by the following raw medicines of percentage by weight:benzoylureas insecticide of 0.1%-30.0%, buprofezin of 0.1%-90.0% and the rest are auxiliary agent, filling material, solvent or water that are commonly used in agricultural chemicals. Comparing with common benzoylureas insecticide and single dose of buprofezin, the insect disinfestation effect of active ingredients of the compositional preparation is more thorough and the action is more lasting.A test indicates that the compositional preparation has an upper virulence to nymphae of brown back rice plant hopper and shows obvious synergism.

Description

technical field [0001] The invention relates to a pesticide, that is, a compound preparation of a benzoylurea insecticide and buprofezin with good control effects on piercing-sucking pests such as aphids, planthoppers, leafhoppers, whiteflies and the like. Background technique [0002] In the prior art, the chemical name of triflumuron is 1-(2-chlorobenzoyl)-3-(4-trifluoromethoxyphenyl)urea. It is used to control Lepidoptera pests on cotton, forest trees, fruit trees and vegetables. Flumuron, also known as the benzoyl urea compound of the fluorine juvenile series, its insecticidal effect is completely different from conventional insecticides. It does not directly kill insects, but interferes with and destroys the normal growth and development of insects, and interferes with the development of insects. The physiological process of insect molting makes insects die slowly, and is safe for humans and animals, and has no pollution to the environment. It meets the requirements of...
