Abstract
Residue of herbicide napropamide [N,N-dimethyl-2-(1-napthoxy)-propionamide] and change of micro-organism were investigated in upland soil under different environmental conditions. Half-lives of degradation were 28.3 days in the sterile soil and 14.6 days in the nonsterile soil, respectively. These results suggest that microorganism remarkably affected the decomposition of napropamide. Napropamide was rapidly degraded in order of 60% > 80%
잔효기간이 긴 것으로 알려진 토양처리형 제초제 napropamide를 밭토양중 여러 환경조전하에 처리하여 이 약제의 토양중 분해성을 검토하고, 이 제초제가 토양미생물 상변화에 끼치는 영향에 대하여 실험을 실시한 결과는 다음과 같다. 살균토양과 비살균토양에서의 napropamide의 분해반감기는 각각 28.3, 14.6 일이었다. 수분함량의 차이에 따른 napropamide의 분해 속도는 60% > 80%
