ENVIRONMENTAL FATE

Clodinafop-propargyl'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, a vapor pressure of 2.4×10-8 mm Hg at 25 deg C indicates clodinafop-propargyl will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase clodinafop-propargyl 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 5 hours. Particulate-phase clodinafop-propargyl will be removed from the atmosphere by wet or dry deposition. Clodinafop-propargyl does not contain chromophores that absorb at wavelengths >290 nm, and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, clodinafop-propargyl is expected to have slight mobility based upon an estimated Koc of 2,000. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.8×10-9 atm-cu m/mole. Clodinafop-propargyl may not volatilize from dry soil surfaces based upon its vapor pressure. A biodegradation half-life in soil of 0.5 to 1.5 days suggests that biodegradation may be an important environmental fate process in soil and water. If released into water, clodinafop-propargyl 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 170 suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism. The hydrolysis half-lives are 184 days at pH 5, 2.7 days at pH 7, and 2.2 hours at pH 9; therefore, hydrolysis will be an important environmental fate process under alkaline conditions. Occupational exposure to clodinafop-propargyl may occur through inhalation and dermal contact with this compound at workplaces where clodinafop-propargyl is produced or used. (SRC)

Usage: Reported by J. Amrein et al. (Proc. Br. Crop Prot. Conf. - Weeds,1989, 1, 71-76). Introduced by Ciba-Geigy AG (now Syngenta AG) and first marketed in 1990. Manufacturers: Syngenta. Fatty acid synthesis inhibitor, by inhibition of acetyl CoA carboxylase (ACCase).

Application: Post-emergence, systemic grass herbicide. Phytotoxic symptoms appear within 1-3 weeks, affecting meristematic tissue. Used for post-emergence control of annual grasses, including Avena, Lolium, Setaria, Phalaris and Alopecurus, in cereals, at 30-60 g/ha. Phytotoxicity Low toxicity to spring and winter wheat. Mainly used in combination with the safener cloquintocet-mexyl.
