摘  要：
[目的]目前用于防除红薯地阔叶杂草和香附子的除草剂较少,通过试验,研究氯吡嘧磺隆对红薯地阔叶杂草和香附子的效果以及对红薯的安全性。[方法]在杂草2~4叶期,红薯3~5片叶施药1次,分4个级别进行施药。[结果]氯吡嘧磺隆应用于红薯田可以有效防治阔叶杂草和香附子,红薯幼苗稍有发黄现象,7~10 d基本恢复,对后期生长和产量基本无影响。[结论]75%氯吡嘧磺隆水分散粒剂推荐用量为45~60 g a.i./hm2,效果较好,对红薯比较安全。

摘  要：
[Aims] Nowadays,few herbicides are found to control the broad-leaf weeds and Cyperusrotundus L.in the sweet potato fields,the aim of the experiment is to study the control effect of halosulfuron-methyl on the weeds in the sweet potato field and its safety to sweet potatoes.[Methods] The herbicide was applied once at the 2-4 leave stage of weeds and at the 3-5 leave stage of sweet potato.[Results] The experiment results showed that applying halosulfuron-methyl in the sweet potato field can effectively control broad-leaf weeds and Cyperusrotundus L.Although the sweet potato seedlings turn a little yellow,they almost get back to normal in 7-10 days,thus doing no harm to the later growth and production of sweet potatoes.[Conclusions] The effects of weed control of halosulfuron-methyl 75% WG at 45-60 g a.i./ha are higher,and safe on sweet potatoes.
