Abstract
Description
Technical Field
[0001] This invention belongs to the field of pesticide and insecticide technology, specifically relating to an insecticidal composition containing benzoylurea. Background Technology
[0002] Benzoylurea insecticides (BPUs) are insecticides based on benzoylurea compounds. They work by inhibiting chitin in the target insects, not by directly killing them, but by hindering or interfering with the normal development of the insects during their individual development, thus reducing their ability to survive, causing them to die, and ultimately leading to the extinction of the population.
[0003] Benzoylurea insecticides have minimal contact action on insects, primarily killing pests through stomach poisoning. Furthermore, benzoylurea insecticides do not exhibit cross-resistance with organophosphates, carbamates, and pyrethroids, and are effective against Lepidoptera, Coleoptera, and Homoptera. They also have minimal impact on organisms lacking chitin. They decompose easily within plants and animals and in the natural environment, resulting in low environmental pollution, making them a widely used class of insecticides for pest control.
[0004] Benzoylurea insecticides have a limited spectrum of activity, limiting their application. While they are effective against specific pests, they are ineffective against some important pests. Furthermore, their insecticidal speed is slow; benzoylurea insecticides act as stomach poisons, not contact pesticides, requiring the pest to ingest the drug to be effective, resulting in poor rapid action. In addition, the excessive, frequent, and irrational use of pesticides in agricultural production leads to increasing resistance in harmful insects, causing more severe damage to crops and making control increasingly difficult. By mixing compounds of formula (I) with two or more benzoylurea insecticides, it is possible to achieve rapid and comprehensive control of different pests, broaden the control spectrum, improve pesticide efficacy, and reduce the development of insecticide resistance.
