Environmental Fate
Soil. Bifenox degrades in soil forming 5-(2,4-dichlorophenoxy)-2-nitrobenzoic acid
and methyl 5-(2,4-dichlorophenoxy)anthranilate (Hartley and Kidd, 1987; Smith 1988).
The average half-life in soils is 7–14 days (Hartley and Kidd, 1987; Humburg et al., 1989)
Plant. Rapidly undergoes ring hydroxylation and subsequent conjugation in rice plants
(Ashton and Monaco, 1991).
Photolytic. The UV photolysis (λ = 300 nm) of bifenox in various solvents was studied
by Ruzo et al. (1980). In water, 2,4-dichloro-3′-(carboxymethyl)-4′-hydroxydiphenyl ether
and 2,4-dichloro-3′-(carboxymethyl)-4′-aminodiphenyl ether were identi
