chlorfluazuron urea is suitable for a variety of fruits and vegetables, and has a special control effect on lepidoptera pests. At present, the production of fruits and vegetables is mainly used for the control of: cruciferous vegetables of cabbage moth, beet moth, cabbage worm, silver moth, will moth, tobacco worm, etc., jacket and melon and fruit vegetables of cotton bollworm, beet moth, tobacco worm, will moth, bean borer and bean borer.

【 Use 1 】

chlorfluazuron insect growth regulators. It is mainly gastric toxicity, has strong touch action, poor permeability and no internal absorption. The insecticidal mechanism is to inhibit the formation of chitosan, hinder the normal molting of pests, make the egg hatching, larval molting, kidney development deformity, and adult emergence, egg laying obstruction, so as to achieve the insecticidal effect. The drug has high activity, slow action rate and long half-life in larvae. It is a broad-spectrum insecticide, effective against a variety of lepidoptera pests and diptera, orthoptera, hymenoptera pests. It has excellent effect on insects on vegetables, and can also be used to control a variety of pests on kale, cotton, tea trees and fruit trees. The first and second instars of vegetable larvae, such as Diamond-moth, beet moth, Streptopteris, rapeseed, etc. were sprayed with 5% cream 2000 ~ 4000 times liquid in the blooming period, the lasting effect was 10 ~ 14 days, and the insecticidal effect was more than 90%. Such as cotton bollworm eggs incubation period, with 5% cream 1000 ~ 2000 times liquid spray, 7d after the insecticidal effect of 80% ~ 90%. When applied at the recommended concentration, there is no harm to crops, and it is safe for bees and non-target beneficial insects.

【 Use 2 】

chlorfluazuron It is a benzoyl urea chittin inhibitor developed by Ishihara Company in Japan in 1982. It has high insecticidal activity, is an efficient, low toxic, and environmentally compatible pesticide variety, will become one of the main varieties to replace the current use of highly toxic insecticides.
