Glufosinate-ammonium'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. If released to air, an estimated vapor pressure of 9.1×10-12 mm Hg at 25 deg C indicates glufosinate-ammonium will exist solely in particulate phase in the ambient atmosphere. Particulate-phase glufosinate-ammonium will be removed from the atmosphere by wet and dry deposition. If released to soil, glufosinate-ammonium is expected to have high to low soil mobility based on Koc values of 9.6 to 1,229. Field studies have indicated that glufosinate-ammonium rarely migrates below 10-15 cm in soil, presumably because of rapid microbial degradation. Microbial degradation is the primary degradation process in soil and occurs rapidly with transformation to 3-methylphosphinyl-propionic acid and 2-methylphosphinyl-acetic acid and ultimately to carbon dioxide. The aerobic half-life in soil is typically 3-11 days with an anaerobic half-life of 5-10 days. Field dissipation half-lives of 6-20 days (avg 13 days) are reported. A laboratory batch and in situ microcosm study demonstrated that glufosinate-ammonium can be persistent and transported in an aquifer with relatively low clay content and little labile organic carbon. If released into water, glufosinate-ammonium is expected to have low to high adsorption 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. An estimated BCF of 3.2 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis and photolysis in water are not expected to be important fate processes with half-lives of greater than 300 days.   

Usage: The ammonium salt was reported as a herbicide by F. Schwerdtle et al. (Z. Pflanzenkr. Pflanzenschutz, 1981, Sonderheft IX, p. 431) and was introduced by Hoechst AG (now Bayer CropScience). Manufacturers: Bayer CropScience. Glufosinate-ammonium is a glutamine synthetase inhibitor; leads to accumulation of ammonium ions, and inhibition of photosynthesis.

Application: Non-selective contact herbicide with some systemic action. Translocation occurs only within leaves, predominantly from the leaf base to the leaf tip. Glufosinate-ammonium is used for control of a wide range of annual and perennial broad-leaved weeds and grasses in fruit orchards, vineyards, rubber and oil palm plantations, ornamental trees and bushes, non-crop land, and pre-emergence in vegetables. Also used as a desiccant in potatoes, sunflowers, etc. For control of annual and perennial weeds and grasses in glufosinate-tolerant crops (oilseed rape, maize, soya beans, sugar beet) developed through gene technology. Applied at 0.4-1.5 kg/ha.
