ENVIRONMENTAL FATE

Oxyfluorfen's production may result in its release to the environment through various waste streams; its use as an herbicide will result in its direct release to the environment. If released to air, a vapor pressure of 2.0×10-7 mm Hg at 25 deg C indicates oxyfluorfen will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase oxyfluorfen 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 33 hours. Particulate-phase oxyfluorfen will be removed from the atmosphere by wet or dry deposition. If released to soil, oxyfluorfen is expected to have no mobility based upon an estimated Koc of 8900. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 8.2×10-7 atm-cu m/mole. A half-life of 7 days in estuarine sediment indicates that biodegadation may be an important environmental fate. If released into water, oxyfluorfen is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Oxyfluorfen had a biodegradation half-life of 27.5 days in estuarine water and 17 days in estuarine sediment. 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 880 suggests the potential for bioconcentration in aquatic organisms is high. Oxyfluorfen showed no significant hydrolysis in 28 days at pH 5-9 (25 deg C).  

Usage: Herbicide reported by R. Y. Yih & C. Swithenbank (J. Agric. Food Chem., 1975, 23, 592). Introduced by Rohm & Haas Co. (now Dow AgroSciences) and first marketed in 1976. Patents: US 3798276. Manufacturers: Dow AgroSciences; Makhteshim-Agan; Sannong. It is a protoporphyrinogen oxidase inhibitor.

Application: Selective contact herbicide, absorbed more readily by the foliage (and especially the shoots) than by the roots, with very little translocation. Control of annual broad-leaved weeds and grasses in a variety of tropical and subtropical crops, by pre- or post-emergence application at rates in the range 0.25-2.0 kg/ha. Particular crops include tree fruit (including citrus), vines, nuts, cereals, maize, soya beans, peanuts, rice, cotton, bananas, peppermint, onions, garlic, ornamental trees and shrubs, and conifer seedbeds. Soya beans and cotton may be injured by contact with oxyfluorfen.
