Abstract
The degradation dynamics of Monosultap in rice plant was studied by high performance liquid chromatography(HPLC) through conducting field trials in Hunan,Zhejiang and Guangxi from 2009 to 2010,respectively.The results showed that degradation of Monosultap in paddyfield water and rice plant was quicker than that in paddyfield soil;the degradation half-life of Monosultap in paddyfield water,paddyfield soil and rice plant was 1.86~2.62 d,6.13~7.70 d and 2.91~3.52 d,respectively.In accordance with the division standards from the Experimental Criteria of Environmental Safety Evaluation for Chemical Pesticides,it could be known that the Monosultap is a kind of low residual and easily degraded pesticide,so it is safe for paddyfield.
