Benzoylurea insecticide and Thiamethoxam compound preparation

Abstract

The invention relates to a pesticide which is a composite preparation formulated by benzoylphenylurea insecticide and thiamethoxam used for controlling lepidoptera, coleopteran, thysanoptera and homopterous pests. Effective components of the preparation comprise 0.1-30.0 percent of the benzoylphenylurea insecticide and 0.1-75.0 percent of the thiamethoxam; the benzoylphenylurea insecticide relates to any one of triflumuron, mieyouniao, hexaflumuron and diflubenzuron; the allowance comprises promoter, filler, solvent or water which is often used in the pesticide. The pesticide has effects of stomach toxicity, contact killing and absorption and is characterized by fast speed and long persistent period. The pesticide can effectively control the lepidoptera, coleopteran and thysanoptera pests and has a high effect on homopterous pests. The pesticide has a good controlling effect on piercing-sucking pests such as aphid, planthopper, leafhopper and whitefly. The complex formulation of the benzoylphenylurea insecticide and the thiamethoxam can kill pests more thoroughly than single preparation of common benzoylphenylurea insecticide and thiamethoxam and has a longer effect.

Description

technical field

[0001] The invention relates to a pesticide, which is a compound preparation of benzoylurea insecticides and thiamethoxam for preventing and controlling insect pests of Lepidoptera, Coleoptera, Thysanoptera and Homoptera. 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 green food in the ...
