| Abstract: | To provide a scientific basis for environmental risk assessment of clodinafop-propargyl.Methods] Soil surface photolysis,anaerobic soil degradation,and water-sediment degradation of clodinafop-propargyl were investigated under laboratory conditions,respectively.Results] Photolysis was not an important fate process of clodinafop-propargyl on soil.Clodinafop-propargyl was degraded quickly in anaerobic soil and water-sediment system,and the degradation half-life were 0.05-0.11 and 0.11-0.17 d,respectively.C... |
