Use
Biological. Rajagopal et al. (1989) reported that Achromobacter sp. and an Arthrobacter sp. utilized propham as a sole carbon source. Metabolites identified were Nphenylcarbamic acid, aniline, catechol, monoisopropyl carbonate, 2-propanol and carbon
dioxide (Rajagopal et al., 1989).
Soil. Readily degraded by soil microorganisms forming aniline and carbon dioxide
(Humburg et al., 1989). The reported half-life in soil is approximately 15 and 5 days at
16 and 29°C, respectively (Hartley and Kidd, 1987).
Groundwater. According to the U.S. EPA (1986) propham has a high potential to leach
to groundwater.
Plant. The major plant metabolite which was identified from soybean plants is isopropyl N-2-hydroxycarbanilate (Hartley and Kidd, 1987; Humburg et al., 1989).
Chemical/Physical. Hydrolysis of propham yields N-phenylcarbamic acid and 2-propanol. The acid is very unstable and is spontaneously decomposed to form aniline and
carbon dioxide (Still and Herrett, 1976). Emits toxic fumes of nitrogen oxides when heated
to decomposition (Sax and Lewis, 1987).
