摘要: 
本研究之主要目的在於分析本達隆除草劑施用於田間, 被作物植體吸收後在植體內及土壤環境中之殘留量變化, 評估此種除草劑對作物產量收穫部位及環境安全之影響.尤其在防除一些耐性作物田間的雜草時可能施用較高劑量下, 對於可能產生之農藥殘毒必須有精確而便利之偵測技術.本試驗主要工作項目: ( 一 )確立玉米、水稻及落花生植株幼苗期對於本達隆除草劑之耐性.( 二 )分析本達隆在玉米、水稻及落花生植株內之殘留量.( 三 )分析除草劑在土壤環境中之殘留量.( 四 )本達隆除草劑殘毒分析法之比較.預期效益: 1.完成bentazon除草劑在稻米、落花生及玉米植體之食用部位及在土壤環境中之殘留量評估, 作為施藥之重要參考.以及評估未來發展或引入除草劑抗性轉殖作物時, 若提高施藥量是否造成危害.2.建立除草劑殘毒之檢測方法及各種分析法之比較.

In order to estimate the effect of applied bentazon on food safety and environmental pollution, the metabolism of bentazon in three major crops in Taiwan, such as corn, rice and peanut, will be determined from early growth stage to harvest, and the bentazon residue in soil will be investigated monthly after bentazon application.Various techniques of bentazon determination including HPLC, TLC, bioassay and chlorophyll fluorescence decay will be established and compared, which could efficiently provide a good monitoring system to detect the residual bentazon in crops or fresh foods as well as that in soil environment.In this study, tolerance of three crops at the early growth stage to foliar-applied bentazon will be determined based on the dose-response analysis using log-logistic model.In addition, the effects of environmental factors, such as microbe, temperature, and light, on the metabolism or degradation of bentazon in soil will also be investigated monthly.
