Residual fate and metabolism of oxadiargyl in paddy

摘要

Oxadiargyl (5-tert-butyl-3-[2, 4-dichloro-5-(prop-2-ynyloxy) phenyl]-1, 3, 4-oxadiazol-2(3H) -one) is a novel protoporphyrinogen IX oxidase herbicide, active pre-emergence on both annual monocotyledons and dicotyledons. The product acts at germination, as the new shoots come in contact with treated soil particles. Oxadiargyl is active via contact activity, with very limited translocation following shoot uptake.
