摘要
经 1997、1999年两年试验证实 ,瑞飞特可有效地防除移栽稻田稗草 ,并对水稻安全。瑞飞特与莎多伏或农得时混用 ,对防除稗草有增效作用 ,同时可防除阔叶杂草 ,并对扁秆草有较强的抑制作用。适宜的施药剂量为单用时 80ml/6 6 7m2 ;与莎多伏或农得时混用时 6 0 80ml/6 6 7m2 (均指商品量 ) ,施药时期为水稻移栽后 57d稗草 1.5叶期。
Investigation was made in 1997 and 1999. The results showed that this herbicide controled Barnyardgrass effectively and safely. A mixture of Rifit and Setoff or Bensulfuron-methyl can increase the effect in controlling barnyardgrass, and also can control broad-leaf weeds. The mixture has strong inhibition to Scipus planiculmis. The suitable dosage is Rifit 80ml/667m 2 or Rifit and Setoff or Bensulfuron-methly 60~80mg/667m 2. The effective time of application is 1.5 leaf age of barnyardgrass.
