%X Degradation，adsorption and field fate of pesticide Dhnehypo have been investigated．The results are as follows：hydrolysis of Dimehypo is very slow under pH range of 3 to 9．Degradation of Dimehypo in soil is mainly microorganism-related．Furthermore，Dimehypo and Nereistoxin can be rapidly degraded under ultraviolet light．Adsorption of Dimehypo by soil is negligible，while Nereistoxin can be sorbed‘o a large extent．After foliar spray in the rice field。distribution of Dimehypo concentration has the following sequence：crop>field water>soil．Field trials have proved considerable tendency of pesticide to leach down the profile，particular attention should be paid to threats of Dimehypo posed to the groundwater．
