骠马及其混用防除春麦田杂草应用技术研究

Research on Application Techniques of Puma and Super its Mixture in Spring Wheat Field

骠马是防除麦田野燕麦（ＡｖｅｎａｆａｔｕａＬ．）的高效选择性除草剂。每ｈｍ２用６．９％骠马ＥＷ６００～７５０ｍｌ，或１０％骠马ＥＣ４５０～５２５ｍｌ，于野燕麦４叶期兑水２２５～２５０Ｌ处理茎叶，除草效果９０％以上，且对小麦安全可靠。骠马与２，４－Ｄ丁酯或２，４－Ｄ加百草敌直接混用，会降低骠马对野燕麦的除草效果，可适当加大骠马用量弥补；间隔７ｄ施用，不影响各自的除草效果。骠马可与苯磺隆直接混用，除草活性独立，杀草谱互补，能一次性防除田间野燕麦和双子叶杂草。

Puma is a kind of the high efficient and selective herbicides to control the Avena fatua L. Using 600～750 ml of 6.9% Puma EW or 450～525 ml of 10% Puma EC added 225～250 L water respectively at 4 leaf period of wild oats, the effectiveness of their contrlling the wild oats above 90% and safe to wheat. Puma+2,4 D or Puma+2,4 D+Dicamba decreased the effectiveness of Puma, but increasing the amount of Puma, the effectiveness would be restored. If using the different herbicides in 7 days, the effects of them were not affected. Puma can be mixed directly with Tribeuron Methyl to control wild oats and broad leaf weeds in fields at the same time. The effectiveness of them were independent and complementing each other.
