ENVIRONMENTAL FATE

Acifluorfen-sodium's production may result in its release to the environment through various waste streams; it's use as a herbicide will result in its direct release to the environment. Acifluorfen-sodium dissociates in the environment to acifluorfen. If acifluorfen is released to air, an estimated vapor pressure of 1.5×10-8 mm Hg at 1.5×10-8 deg C indicates acifluorfen will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase acifluorfen 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 18 days. Particulate-phase acifluorfen will be removed from the atmosphere by wet or dry deposition. If released to soil, acifluorfen-sodium has a pKa of 3.86 indicating it will exist as an anion in moist soil and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterpartsr. Acifluorfen is expected to have very high to low mobility based upon measured Koc values which range from 44 to 684. A biodegradation half-life range in soil of 108-200 days for acifluorfen indicates that biodegradation is not an important environmental fate process in soil. However, under anaerobic conditions a half-life of 30 days has been reported. Volatilization from moist soil surfaces is not expected to be an important fate process for acifluorfen since anions do not volatilize. If released into water, acifluorfen is expected to adsorb to some suspended solids and sediment based upon the measured Koc values. Acifluorfen exhibits a photolysis half-life in water of 2 hours. An aerobic biodegradation half-life in water of 117 days for acifluorfen indicates that biodegradation is not an important environmental fate process in water. However, under anaerobic conditions a half-life of 2.75 days has been reported. The pKa indicates acifluorfen-sodium will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Acifluorfen-sodium is hydrolytically stable in the dark. Occupational exposure to acifluorfen-sodium may occur through inhalation and dermal contact with this compound at workplaces where acifluorfen-sodium is produced or used. Use data indicate that the general population may be exposed to acifluorfen-sodium via dermal contact with consumer products containing this compound. (SRC)

Usage: First registered in US in 1980. Introduced as a herbicide independently by Mobil Chemical Co. (now Bayer CropScience, who no longer market it) and by Rohm & Haas Co. (who transferred rights to BASF AG in 1987). Patents: DE 2311638 Manufacturers: Toll manufactured for BASF by Rohm & Haas Inc.

Application: Selective contact herbicide, absorbed by the foliage and roots, with negligible translocation. Activity is enhanced by sunlight. Used post-emergence for the control of annual broad-leaved weeds (Abutilon, Amaranthus, Datura, Euphorbia, Polygonum, Ipomoea, Xanthium spp.), with some effects on grasses, in soya beans, peanuts and rice. Applied at 0.2 to 0.6 kg/ha, depending on crop. Soya beans show good tolerance, although some burning may be seen on new leaf growth, which is readily outgrown. Phytotoxicity increased if mixed with fertilisers.
