田间试验结果表明: 30%丁· 乳油对水稻移栽田杂草防效显著。在水稻移栽后7天用丁· 70、90、110g/667m2施药后 20天总株防效分别为 68.02%、89.97%、92. 18%;施药后 60天总株 防效分别为62、22%、86.99%、89.31%,总鲜重防效分别为76.93%、86.65%、93.13%。极显著优 于单剂A,虽与单剂B防效相当,但农本明显低于单剂B,丁· 对水稻安全。
The results of field experiments showed that 30% D EC was effective in controlling weeds in transplanted rice fields. In the 7 days after transplanting rice with 70, 70,110 g / 667m2 d 20 days after the control of the total plant were 68.02%, 89.97%, 92. 18% respectively. The control effect of total plant on the 60th day after the pesticide application was 62, 22%, 86.99% and 89.31%, respectively. The total fresh weight control efficiency was 76.93%, 86.65% and 93.13% . Very significantly superior to single dose of A, although with a single dose B control effect is equivalent, but the farm was significantly lower than a single dose of B, D, on rice safety.
