Abstract

Uptake, translocation, and metabolism of 14C-MBR-18337 {[N-[(4-ethylthio)-2-(trifluoromethyl)phenyl] methanesulfonamide]} in soybean [Glycine max (L.) Merr.] and johnsongrass [Sorghum halepense (L.) Pers.] plants and cell cultures were studied. Sixty-five percent of the 14C recovered from soybean (65% of applied) was on or in the treated leaf, compared to 81% of the 14C recovered from johnsongrass (43% of applied). Translocation of the 14C from the treated leaf of soybean was greater than from the treated johnsongrass leaf, and was primarily to the apical leaves of both species. MBR-18337, its sulfoxide, sulfone, and an unidentified polar component(s) were isolated from intact plants and cell cultures of both species. Soybean plants and cells contained greater proportions of the polar component(s) than johnsongrass plants and cells.
