Benzoylurea insecticides. Inhibit the synthesis of insect polysaccharide. It is mainly gastric toxic and has contact killing effect. The residue period is longer, but the efficacy is slower. It is used to control many pests of Lepidoptera, especially for larvae, and is safe for crops and natural enemies. For example, the control of Plutella xylostella, Spodoptera litura, Spodoptera exigua, Plutella xylostella and Plutella xylostella should be sprayed with 25% suspension solution 500-1000 times during the period of egg hatching to the peak of 1-2 instar larvae.
 
To control corn borer and maize iron beetle, eggs and newly hatched larvae can be killed by filling heart leaves or spraying 1000-2000 times of 20% suspension solution at the initial hatching or oviposition peak. During the period of larval emergence, 20% suspension concentrate was added to 75 ~ 150g/hm2 and water 750KG to spray. In order to prevent and control citrus leaf miner, spray with 25% suspending agent 2000 times in the initial stage and hatching stage.

Volbor is a new insecticide, which has gastric toxicity to many important insect larvae. It interferes with the deposition of the epidermis and causes insects to die of normal molting or metamorphosis. It can also inhibit the formation of the epidermis during the development of the embryos in the eggs of insects, so that the eggs can not normally develop and hatch, at the same time, it can also inhibit the fecundity of insects.
 
This product has wide insecticidal spectrum, especially for Lepidoptera larvae. Because of its unique mechanism of action, low toxicity to humans and livestock, and little harm to natural enemies, it is a relatively good selective insecticide developed in recent years.
