Common Name: Diflubenzuron Chemical name: 1-(4-chloropehenyl)-3-(2,6-difluorobenzoyl)urea CAS No.: 35367-38-5 Molecular Weight: 310.7 Molecular Formula: C14H9ClF2N2O2 Usage: Insecticides Diflubenzuron is a benzoylphenyl urea used on forest and field crops to selectively control insects and parasites. Principal target insect species are the gypsy moth, forest tent caterpiller, several evergreen eating moths, and the boll weevil. It is also used as a larvae control chemical in mushroom operations and animal houses. Diflubenzuron is a stomach and contact poison. It acts by inhibiting the production of chitin, a compound that makes the outer covering of the insect hard and thus interferes with the formation of the insect's cuticle or shell. It is available as a suspension concentrate, wettable powder, or in granules.
Physical and Chemical Properties: Tech Diflubenzuron is a white crystalline solid. Its melting point is 210-230 degree C (technical with decomposition) . The vapor pressure 50 degree C (tested by the method of extrapolation) is<0.033 mPa. Solubility(25 degree C, w/w): 0.14 mg/L at 20 degree C, insoluble in water, Adsorption Coefficient: 10,000
Toxicity: No overt signs of toxicity were observed in any of the acute studies conducted. The oral LD50 in rats and mice is greater than 4640 mg/kg, and the dermal LD50 is greater than 10,000 mg/kg in rats and greater than 4000 mg/kg in rabbits. It is nonirritating to skin and slightly irritating to eyes. Application:Diflubenzuron is used specially to kill lepid-optera,also to kill coleoptera and diptera,It may not cause obvious bad Influence to natural enemy. Insecticide, larvicide, ovicide, insect growth regulator acting by interference with deposition of insect chitin
