Abstract
This experiment was conducted to determine the residual amount of dimepiperate (S-1-methyl-1-phenylethyl piperidine-1-carbothioate) and dimepiperate-OH(S-1-methyl-1-phenylethyl-4-hydroxy piperidine-1-carbothioate) in surface water and leachate using a lysimeter system. In surface water, the concentration of dimepiperate was 851-897 ppb in the treatment of 3.0 Kg prod/10a. 1,755-1,781 ppb in the treatment of 6.0 Kg prod/10a 1 day after the treatment. The amount of dimepiperate gradually decreased and was infinitesimal from 35 days after the treatment. In leachate dimepiperate was detected from the 45 days, but its concentration was very low, below 1 ppb, compared to that in surface water. The metabolite of dimepiperate, dimepiperate-OH in surface water was detected after the application of dimepiperate. The highest level of 88-173 ppb occurred 2 day after the treatment of dimepiperate and then decreased gradually. The residual concentration was below 2.13 ppb during 28-63 days. In leachate, the concentration of dimepiperate-OH in the different treatments in the range of 0.5-11 ppb from the 21 days, although each treatment showed different detected date and concentration. The detected concentration showed a little change until 63 days.
