|
摘要
[目的]为筛选出对花生田杂草防治效果高、安全性好的除草剂。[方法]采用田间小区试验的方法,测定了8种土壤处理除草剂对花生田杂草的防除效果及安全性。[结果]40%砜吡草唑SC、50%丙炔氟草胺WP、40%双氯磺草胺WG、80%唑嘧磺草胺WG、240 g/L甲咪唑烟酸AS各处理和500 g/L三氟草嗪SC 100 g a.i./hm~2处理对花生田杂草防治效果较好,总体杂草鲜重防治效果均在90%以上,但40%砜吡草唑SC,300 g/L三氟草嗪SC对花生安全性较差,株高显著低于人工除草处理,产量损失达1.70%～3.94%。[结论]因此,在花生田土壤喷雾处理可以选用50%丙炔氟草胺WP、40%双氯磺草胺WG、80%唑嘧磺草胺WG、240 g/L甲咪唑烟酸AS进行杂草防除,对花生安全性较好。
[Aims]This study aims to select herbicides with high control effect and good safety. [Methods]Field trials were carried out with eight herbicides to evaluate the control effects and safety in peanut field. [Results]The results indicated that pyroxasulfone 40% SC, flumioxazin 50% WP, diclosulam 40% WG, flume-tsulam 80% WG, imazapic240 g/L AS and trifludimoxazin 500 g/L SC 100 g/ha had good control effect with above 90% on weeds in peanut field,however, pyroxasulfone 40% SC and trifludimoxazin 500 g/L SC had poor safety to peanut with the plant height significantly lower than artificial weeding treatment and the yield loss was 1.70-3.94%. [Conclusions]Therefore,flumioxazin 50% WP, diclosulam 40% WG, flumetsulam 80% WG, imazapic 240 g/L AS could be used by soil treatment in peanut field, which is safe to the crop and indicate good control effect to weeds.
