摘要
通过田间试验比较了 1 2 %虎威微胶囊和 2 5%虎威水剂对大豆田阔叶杂草的防除效果。结果表明 ,1 2 %虎威微胶囊比 2 5%虎威水剂有更高的除草活性。使用 1 2 %虎威微胶囊 2～ 3L/hm2 ,对大豆田阔叶杂草有良好的防效 ,虽然大豆可产生接触性药害斑 ,但可恢复 。
Comparison of control effect against broad-leaved weeds in soybean field between 12%fomesafen ME and 25% fomesafen LC was done in 1996～1997.The result showed that 12% fomesafen ME had the better control effect than 25% fomesafem LC as the same effective dose.At the dosage of 2～3L/ha,12% fomesafen ME could give good control effect to broad-leaved weeds and injury could occur to soybean after application,but plant could recover and yield not be affected.
