Product description:

The new acyl urea insecticides, in addition to other acyl urea insecticidal characteristics, have a broad insecticidal spectrum, especially for cotton bollworm pests, and have special effects on gypsy moths, canopy caterpillars, fir poisonous moths, sweet budworm Insect pests such as Spodoptera frugiperda have good effects and are ineffective against mites. It has strong knockdown power, faster insecticidal effect than other acyl ureas, and has high contact eggicidal activity, which be used alone or mixed. The application period is not strict, and can control pests that have developed resistance to organic phosphorus and pyrethroids. It is a benzoylurea insect growth regulator that kills pests by inhibiting the synthesis of insect chitin. The utility model has the characteristics of high insecticidal activity, broad insecticidal spectrum, strong knockdown power and quick effect. Its mechanism is to inhibit the formation of Chitosan, hinder the normal molting and metamorphosis of pests, but also inhibit the speed of feeding pests.It can control Coleoptera, Diptera, Lepidoptera and homoptera pests on cotton and fruit trees, and has ovicidal activity.. In particular, it has a good effect on pests such as cotton bollworm and is ineffective against mites.It is used to control cotton bollworm and pink bollworm in the peak hatching period. , before the larvae worms enter the bud and boll, it is sprayed with 5% to 1500 to 2000 times liquid.
