ENVIRONMENTAL FATE

Clethodim's production may result in its release to the environment through various waste streams; its use as a herbicide will result in its direct release to the environment. If released to air, an estimated vapor pressure of 2.7×10-9 mm Hg at 25 deg C indicates clethodim will exist solely in the particulate phase in the atmosphere. Particulate-phase clethodim will be removed from the atmosphere by wet or dry deposition. Clethodim contains chromophores that absorb at wavelengths >290 nm, and therefore may be susceptible to direct photolysis by sunlight. If released to soil, clethodim is expected to have no mobility based upon an estimated Koc of 8000. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.2×10-11 atm-cu m/mole. Biodegradation half-lives of 1 to 3 days using 5 unspecified aerobic soils suggest that biodegradation may be an important environmental fate process in soil and water. If released into water, clethodim 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 280 suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism. Clethodim hydrolysis is pH dependent with degradation of 37%, 7%, and 0% reported at pH 5, pH 6, and pH 7, respectively, after 20 hours incubation. Occupational exposure to clethodim may occur through inhalation and dermal contact with this compound at workplaces where clethodim is produced or used. (SRC)

Usage: Herbicide reported by R. T. Kincade et al. (Proc. 1987 Br. Crop Prot. Conf. - Weeds, 1, 49). Introduced by Chevron Chemical Co. Patents: GB 2090246 Manufacturers: Arvesta; Shenyang. Fatty acid synthesis inhibitor, by inhibition of acetyl CoA carboxylase (ACCase).

Application: Systemic herbicide, rapidly absorbed and readily translocated from treated foliage to the root system and growing parts of the plant. Post-emergence control of annual and perennial grasses, at 60-240 g/ha, in a wide range of broad-leaved crops (including such field crops as soya beans, cotton, flax, sunflowers, alfalfa, peanuts, oilseed rape, sugar beet, tobacco, and potatoes), vegetable crops, trees and vines. To be used with a non-phytotoxic crop oil concentrate. Phytotoxicity Good tolerance in broad-leaved crops.
