ENVIRONMENTAL FATE
Flufenoxuron's production may result in its release to the environment through various waste streams; its use as an insecticide/acaracide will result in its direct release to the environment. If released to air, a vapor pressure of 4.89×10-14 mm Hg at 20 deg C indicates flufenoxuron will exist solely in the particulate phase in the atmosphere. Particulate-phase flufenoxuron will be removed from the atmosphere by wet or dry deposition. Flufenoxuron is stable to natural sunlight, and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, flufenoxuron is expected to have no mobility based upon an estimated Koc of 1.3×104. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.6×10-12 atm-cu m/mole. Flufenoxuron may not volatilize from dry soil surfaces based upon its vapor pressure. Biodegradation data were not available. If released into water, flufenoxuron is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 5400 suggests the potential for bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism. Hydrolysis half-lives of 112 days (pH 5), 104 days (pH 7), 36.7 days (pH 9), and 2.7 days (pH 12) indicate that the compound does undergo hydrolysis in the environment but the rate is affected by pH. An aqueous photodegradation half-life of 11 days in ambient water was reported. Occupational exposure to flufenoxuron may occur through inhalation and dermal contact with this compound at workplaces where flufenoxuron is produced or used. Limited monitoring data indicate that the general US population may be exposed to flufenoxuron via ingestion of imported food.
Usage: Flufenoxuron was discovered by M. Anderson, developed by Shell International Chemical Co., then American Cyanamid Cc. is the main manufacturer of the Chemical.
Application: Control of immature stages of many phytophagous mites (Aculus, Brevipalpus, Panonychus, Phyllocoptruta, Tetranychus spp) and insect pests on pome fruit, vines, citrus fruit, tea, cotton, maize, soya beans, vegetables and ornamentals. Applied at 25200 g/ha, depending on the crop and pests.
