ENVIRONMENTAL FATE
Bifenthrin's production may result in its release to the environment through various waste streams; its use as an insecticide/acaricide will result in its direct release to the environment. If released to air, a vapor pressure of 1.3410-8 mm Hg at 25 deg C indicates bifenthrin will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase bifenthrin will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 4 hours. Particulate-phase bifenthrin will be removed from the atmosphere by wet and dry deposition. Pyrethroids such as bifenthrin absorb light at wavelengths >290 nm; therefore, bifentrhin may be susceptible to direct photolysis by sunlight. If released to soil, bifenthrin is expected to have no mobility based upon a Koc of range of 8,387 to 14,332. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 1.010-6 atm-cu m/mole. However, volatilization from moist soil surfaces is expected to be attenuated by adsorption. Bifenthrin is not expected to volatilize from dry soil surfaces based upon its vapor pressure. Using soils typical of Australia, bifenthrin, present at a concentration of 4.5 mg/kg and incubated for 24 months exhibited half-lives of 1332 to 1410 days, indicating that biodegradation is not an important environmental fate process in soil. If released into water, bifenthrin is expected to adsorb to suspended solids and sediment based upon the Koc. The compound is very stable in aquatic environments indicating that biodegradation is not an important environmental fate process in water. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 62 years if adsorption is considered. A log BCF of 3.8, corresponding to a BCF of 6,100 suggests that bioconcentration in aquatic organisms is very high. Bifenthrin was reported to be stable to hydrolysis at pH 5, 7, and 9 at 25 deg.
Usage: Insecticide and acaricide reported by H. J. H. Doel et al. (Meded. Fac. Landbouwwet. Rijksuniv. Gent, 1984, 49, 929) and A. R. Crossman et al. (ibid., p. 939). Introduced by FMC Corp. Acts on the nervous system of insects, disturbs the function of neurons by interaction with the sodium channel.
Application: Contact and stomach action. Effective against a broad range of foliar pests, including Coleoptera, Diptera, Heteroptera, Homoptera, Lepidoptera and Orthoptera; it also controls some species of Acarina. Crops include cereals, citrus, cotton, fruit, grapes, ornamentals and vegetables. Rates range from 5 g/ha against Aphididae in cereals to 45 g/ha against Aphididae and Lepidoptera in top fruit.
