7种除草剂对冀北地区胡麻田莜麦的防除效果

The Controlling Effect of 7 Kinds of Herbicides on Naked Oats in Flax Field of North of Hebei Province

为筛选防除胡麻田莜麦的新型、高效、安全除草剂,在河北省张北县喜顺沟村开展了150 g/L精吡氟禾草灵乳油、15%炔草酯可湿性粉剂、10%精喹禾灵乳油、240 g/L烯草酮乳油、10.8%高效盖草能乳油、50 g/L唑啉草酯乳油和12.5%烯禾啶乳油7种除草剂防除胡麻田莜麦的田间试验,对7种药剂的安全性和防除效果进行了分析。结果表明:7种除草剂在试验剂量下均对胡麻安全,其中150 g/L精吡氟禾草灵乳油、15%炔草酯可湿性粉剂、10%精喹禾灵乳油、240 g/L烯草酮乳油、10.8%高效盖草能乳油和50 g/L唑啉草酯乳油6种除草剂对胡麻田莜麦的株防效和鲜重防效均达到了98%以上,防除效果明显,可以在生产上大面积推广。

In order to screen out the new efficient and safety herbicides which control the naked oats in flax field,the controlling effects of 7 kinds of herbicides including 150 g/L fluazifop-p-butyl EC,15% clodinafop-propargyl WP,10% quizalofop-p-ethyl EC,240 g/L clethodim EC,10.8% haloxyfop-p-methyl EC,50 g/L pinoxaden EC and 12.5% sethoxydim EC on naked oats in flax field were studied in Xishungou Villige of Zhangbei County,and the safety and control effect of the herbicides were analyzed.The results showed that the 7 kinds of herbicides in the test dose were all safety to flax,and the strain controlling effect and fresh weight controlling effect of 150 g/L fluazifop-p-butyl EC,15% clodinafop-propargyl WP,10% quizalofop-p-ethyl EC,240 g/L clethodim EC,10.8% haloxyfop-p-methyl EC and 50 g/L pinoxaden EC to naked oats in flax field all reached more than 98%,these herbicides were suitable for promotion in the prduction.
