摘要

本研究探討除草劑10%環磺隆可濕性粉劑，在臺灣地區不同氣候環境下施用，對一、二期作移植水稻田雜草之防除效果及稻株藥害之評估，提供安全有效之使用方法，作為農民在田間應用之依據。綜合藥效及藥害試驗結果，測試藥劑環磺隆於插秧後6-15天（一期作）或3-10天（二期作），以每公頃0.45公斤或0.60公斤施用，皆可有效防除鴨舌草、心葉母草、尖瓣花等闊葉雜草，及莎草科之球花蒿草，但對稗草之防治效果較差。同時對稻株生育及稻穀產量，並未引起株形異常、生長抑制及減產等藥害現象發生。

Chemical weed control with effective and highly active herbicides has been very useful and convenient means. It has contributed to stable crop production and is labor saving. Recent herbicides have had characteristics such as high effectiveness without causing environmental pollution or harmful effects, and appropriate herbicides having high activity, low toxicity, high selectivity and being non-persistent have been developed. Cyclosulfamuron was applied for weed control in paddy rice. The experiments were conducted by Taichung, Kaohsiung and Taoyuan District Agricultural Research and Extension Stations to evaluate cyclosulfamuron for rice crop tolerance and efficacy of weed control. Cyperus difformis, Monochoria vaginalis, Lindernia cordiforia, and Sphenoclea zeylanica. were controlled with high efficiency by applications of cyclosulfamuron with 0.45 and 0.60 kg/ha, except Echinochloa crus-galli. Cyclosulfamuron at 0.45 and 0.60 kg/ha was safe on tested rice cultivars. They can be applied at 6-15 days (1(superscript st) crop) or 3-10 days (2(superscript nd) crop) after rice transplanting and have to date proven very effective in the control of a wide range of annual and perennial broad leaf weeds, as well as sedges.
