Diflubenzuron Powder Usage and Synthesis.

Gastric toxicity and contact, no endosorption, difenuron is a benzoylurea insect growth regulator. The mechanism of action is to inhibit the synthesis of chitin, which is effective to a variety of pests of Lepidoptera, and has no harmful effects on plants under the effective dosage, and has no adverse effects on beneficial organisms such as birds, fish, shrimp, frogs, bees, ladybugs, foot beetles, spiders, lacewings, trichogramma, ants, parasitic wasps, etc., and has slow effect on pests.

Uses of Diflubenzuron powder.

Flufenuron is a new insecticide which has gastric toxic effects on the larvae of many important pests. It dies by interfering with epidermal deposition so that the insect cannot molt normally or metamorphose. It can also inhibit the formation of the epidermis during the development of the embryo in the egg, so that the egg can not develop and hatch normally, and it also has a certain inhibitory effect on the fertility of the insect. The insecticidal spectrum of the product is wide, especially the effect on lepidoptera larvae is particularly obvious. Because of its unique mechanism of action, it is low toxic to humans and animals and less harmful to natural enemies, and it is a relatively good selective insecticide developed in recent years.
