ENVIRONMENTAL FATE

Acephate's production may result in its release to the environment through various waste streams; its use as an insecticide will result in its direct release to the environment. If released to air, a vapor pressure of 1.7×10-6 mm Hg at 25 deg C indicates that acephate is expected to exist in both the vapor and particulate-phases in the ambient atmosphere. Vapor-phase acephate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 34 hours. Particulate-phase acephate will be removed from the atmosphere by wet or dry deposition. Acephate was photolytically stable in aqueous solutions exposed to natural sunlight, suggesting photolysis will not be an important fate process. If released to soil, acephate is expected to have very high mobility based upon a Koc value of 4.7 measured in a clay loam. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 5×10-13 atm-cu m/mole. Volatilization from dry soil is not expected based upon the vapor pressure. Acephate is non-persistent in the environment with observed half-lives of <3 days in laboratory studies and terrestrial field dissipation studies. If released into water, acephate is not expected to adsorb to suspended solids and sediment based upon the Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. Acephate was stable to hydrolysis at pH 5 and 7, but degraded with a half-life of 18 days at pH 9. A BCF value of 10 measured in fish suggests that bioconcentration in aquatic organisms is low. Occupational exposure to acephate may occur through inhalation of dust and dermal contact with this compound at workplaces where acephate is produced or used. Monitoring data indicate that the general population may be exposed to acephate via ingestion of food containing acephate. (SRC)

Usage: Insecticide described by J. M. Grayson (Pest Control, 1972, 40, 30). Chemical structure-biological activity relationships of analogues summarised by P. S. Magee (Residue Rev., 1974, 53, 3).

Application: Uses Control of a wide range of chewing and sucking insects, e.g. aphids, thrips, lepidopterous larvae, sawflies, leaf miners, leafhoppers, cutworms, etc., at 0.5-1.0 kg/ha, in fruit (including citrus), vines, hops, olives, cotton, soya beans, peanuts, macadamia nuts, beet, brassicas, celery, beans, potatoes, rice, tobacco, ornamentals, forestry, and other crops. Of moderate persistence, with residual activity lasting c. 10-21 d. Phytotoxicity Non-phytotoxic to most crops, but marginal leaf burn may occur on Red Delicious apples.
