【摘要】 为评价9种除草剂对花生田杂草的防除效果及对花生安全性,采用茎叶处理的方法进行田间试验。结果表明,茎叶处理药剂240 g/L甲咪唑烟酸水剂72 g/hm~2,500 g/L三氟草嗪悬浮剂150、300 g/hm~2,480 g/L灭草松水剂2160 g/hm~2,10%乙羧氟草醚乳油60、120 g/hm~2,70%嗪草酮可湿性粉剂577.5、1155 g/hm~2处理对花生田杂草防治效果较好,防效均在90%以上。但500 g/L三氟草嗪悬浮剂150、300 g/hm~2,75%氯吡嘧磺隆水分散粒剂45、90 g/hm~2,70%嗪草酮可湿性粉剂577.5、1155 g/hm~2对花生安全性较差,植株明显低于人工除草处理。因此,在花生田茎叶喷雾可选用240 g/L甲咪唑烟酸水剂、480 g/L灭草松水剂、10%乙羧氟草醚乳油进行杂草防除,对花生安全性较好。更多还原

【Abstract】 The paper aims to evaluate the control effects of 9 herbicides on weeds in peanut field and safety of peanut. We carried out field trials by using stems & leafs treatments. The results showed that: the treatments of240 g/L imazapic AS 72 g/hm~2, 500 g/L trifludimoxazin SC 150, 300 g/hm~2, 480 g/L bentazon AS 2160 g/hm~2,10% fluoroglycofen-ethyl EC 60, 120 g/hm~2, 70% metribuzin WP 577.5, 1155 g/hm~2 had good control effect on weeds in peanut field with the value above 90%, but the treatments of 500 g/L trifludimoxazin SC 150,300 g/hm~2, 75% halosulfuron-methyl WDG 45, 90 g/hm~2, 70% metribuzin WP 577.5, 1155 g/hm~2 had poor safety for peanut with the plant height significantly lower than that of artificial weed treatment. Therefore,spraying 240 g/L imazapic AS, 480 g/L bentazone AS, and 10% fdluoroglycofen-ethyl EC on stems & leafs in peanut field is safe to crop and has good control effect on weeds.更多还原
