Fate of the Herbicide Sethoxydim in Sugar Beet
Journal of Pesticide Science, 1988 除草剤セトキシジムのサトウダイコンにおける挙動を [4-14C] 標識セトキシジムの葉面処理実験により研究した. 処理葉中の14Cはしだいに減少し, 7日後に処理量の37%となり, 主に非処理葉に移行し, 根には少なかった. 移行した14C量は, 3日後に最大となり, それぞれ, 15.9, 4.2%であった. 非処理葉, 根におけるセトキシジム換算濃度は, それぞれ, 9.7ppm (処理後3日), 15.4ppm (同1日) の最大値となった後減少し, 90日後には, ともに0.02ppm以下となった. サトウダイコン中で, セトキシジムは速やかに代謝され, スルホキシド, スルホン, それらのオキサゾール体, 脱エトキシ体になり, さらに, 抱合体となった.

Comparison of herbicidal properties of alloxydim and sethoxydim.
Journal of Weed Science and Technology, 1989 アロキシジムとセトキシジムの殺草特性を検討すると同時にその相違を調べた。1. 27種のイネ科植物に対する活性をポット試験で茎葉散布処理を行い調べた結果, 両剤いずれも処理量を高めるとほとんどの草に対し除草効力を示した。しかしオオウシノケグサ (Festuca rubra L.) およびスズメノカタビラ (Poa annua L.) に対しては効力は低く, この両種は強い耐性をもつことが明らかとなった。全体的にみてアロキシジムは0.5kg/haの処理で高い効力を示し, 他方セトキシジムでは0.125kg/haないし0.25kg/haでこれと同等の活性を示した。これよりセトキシジムはアロキシジムの3ないし4倍の活性を有することが明らかとなった。2.
