The influence of MG-191 safener on the uptake, translocation and metabolism of [l4C]acetochlor and [14C]EPTC was studied. The amounts of absorbed radioactivity by maize seedlings at 3, 6, 24, and 72 h after applications of [l4C]labeled herbicides and [l4C]MG-191 were different. Plants treated with [l4C]acetochlor took up 30to 50-fold more radiolabel with in 72 h than [14C]EPTCor [14C]MG-191-tr...
