                                  The latest generation replaces urea pesticides. The pesticide can kill insect pests by acting on insect larvae and stopping the peeling process, especially for leaf-eating caterpillars such as fruit trees, and has a unique killing mechanism for thrips, rust Mites and whitefly, resistant to synthetic Pyrethrins and organophosphorus pesticides. It is safe for crops, such as corn, vegetable, orange, cotton, potato, grape and soybean. It is suitable for integrated pest management. The insecticide did not cause the resurgence of piercing-sucking pests and had a mild effect on the adults of beneficial insects and predatory spiders. Long-lasting effect, rain erosion resistance, useful adult arthropod has a selective. After treatment, the first effect was slow, and it could kill the eggs, and the effect was observed 2 ~ 3 days after treatment. Low toxicity to bees and bumblebees, low toxicity to Mammalian MITE Mites, bees can be used when collecting honey. It is safer than organophosphorus and Carbamate pesticides, and can be used as a good mixture to control lepidopteran pests. Low-dose application still has good control effect on caterpillars and flower thrips larvae, can prevent virus transmission, and can effectively control pyrethroid and organophosphate-resistant lepidopteran pests. The pesticide is selective and long-lasting, and has good control effect on potato borer in later period. Besides, it can increase the yield significantly by reducing the times of spraying.
