摘　　要： 稻田在不同时间施用稻思达结果表明,移栽前1 d,3 d施药,对水稻有明显药害;移栽前5 d施药,则无明显药害。移栽后5 d,稻思达混砂或混肥撒施均对水稻不会产生药害,具有较好的安全性;各处理在药后20 d,40 d对各种禾本科、莎草及阔叶杂草均有很高的防效。 The control effects of Topstar on the weeds in rice field are studied in this paper. The results show that the crops have distinct phytotoxicity reaction when Topstar is used 1 day or 3 days before the transplantation of seedling, but no phytotoxicity reaction 5 days before it. Mixed with grit or fertilizer, the herbicide applied to the field after the transplantation is safe to the rice. Topstar is highly effective to many kinds of weeds such as gramineae, cyperaceae and broad-leaf weeds 20 days and 40 days after the treatment.
