Diflubenzuron, 除虫脲 other name:N-[[(4-chlorophenyl)amino]carbonyl]-2,6-difluorobenzamide-1,2,4-triazole-1-ethanol

CAS No.: [35367-38-5]

Molecular Formula: C14H9ClF2N2O2

Diflubenzuron is a benzoylurea-type insecticide of the benzamide class. It is used in forest management and on field crops to selectively control insect pests, particularly forest tent caterpillar moths, boll weevils, gypsy moths, and other types of moths. The mechanism of action of diflubenzuron involves inhibiting the production of chitin which is used by an insect to build its exoskeleton.

Diflubenzuron is an acaricide/insecticide (insect growth regulator) used to control many leaf eating larvae of insects feeding on agricultural, forest and ornamental plants (e.g. gypsy moths, mosquito larvae, rust mites). Diflubenzuron is used primarily on cattle, citrus, cotton, mushrooms, ornamentals, standing water, forestry trees and in programs to control mosquito larvae and gypsy moth populations. Formulations include a soluble concentrate, flowable concentrate, wettable powder and a pelleted/tableted. Diflubenzuron is applied by airblast, aircraft and hydraulic sprayers.

Chitin synthesis inhibitor; and so interferes with the formation of the insect cuticle. This action is quite specific; related biochemical processes, such as chitin synthesis in fungi, and biosynthesis of hyaluronic acid and other mucopolysaccharides in chickens, mice and rats are not affected.

Mode of action
Non-systemic insect growth regulator with contact and stomach action. Acts at time of insect moulting, or at hatching of eggs.

For control of a wide range of leaf-eating insects in forestry, woody ornamentals and fruit. Controls certain major pests in cotton, soya beans, citrus, tea, vegetables and mushrooms. Also controls larvae of flies, mosquitoes, grasshoppers and migratory locusts. Used as an ectoparasiticide on sheep for control of lice, fleas and blowfly larvae. Due to its selectivity and rapid degradation in soil and water, diflubenzuron has no or only a slight effect on the natural enemies of various harmful insect species. These properties make it suitable for inclusion in integrated control programmes. Diflubenzuron is effective at 25-75 g/ha against most leaf-feeding insects in forestry; in concentrations of 0.01-0.015% a.i. against codling moth, leaf miners and other leaf-eating insects in top fruit; in concentrations of 0.0075-0.0125% a.i. against citrus rust mite in citrus; and at a dosage of 50-150 g/ha against a number of pests in cotton (cotton boll weevil, armyworms, leafworms), soya beans (soya bean looper complex) and maize (armyworms). Also for control of larvae of mushroom flies in mushroom casing (1 g/m2); mosquito larvae (25-100 g/ha); fly larvae in animal housings (0.5-1 g/m2 surface); and locusts and grasshoppers (60-67.5 g/ha).
