威霸和国产虎威防治大豆田杂草试验

The Efficacies of Whip Super and Fomesafen on Weeds Controlling in Soybean Field

试验结果表明：７５０ｍｌ／ｈａ虎威能有效地控制大豆苘麻和青葙子；６００—７５０ｍｌ／ｈａ威霸防除大豆田野泰和芒稷达极满意效果；克阔乐不宜与威霸混用。

The results showed that 750ml/ha Fomesafen controlled Celosia argentea L and Abutilon theophrasti Medic satisfactorily and that Whip Super 600￣750 ml/ha got more than 93% efficacies in controlling Eriochloa villosa (Thunb) Kunth and Echinochloa colonum (L) Link. When they were mixed together, Cobra and Whip Super reduced the weed-controlling efficacies and increased phytotoxicity each other.
