安徽省蚌埠市一读者来电话说,以前他种番茄都没有用除草剂除草,田间杂草多,尤其是阔叶杂草多。现在番茄苗又要移栽了,听别人说番茄田也可以用除草剂除草。他问,可以用什么除草剂。番茄移栽前可以用二甲戊灵、仲丁灵、异丙甲草胺等药进行土壤封闭处理,可以防除禾本科杂草及部分阔叶杂草,对禾本科杂草的防效优于对阔叶杂草的防效。番茄生长期田间的禾本科杂草也较易用药防除,高效氟吡甲禾灵、精喹禾灵、烯草酮等药均可选用。番茄移栽前用乙氧氟草醚、氯吡嘧磺隆等药进行土壤封闭处理,对阔叶杂草有较好的防除效 A reader from Bengbu City, Anhui Province called by telephone to say that in the past he had not used any herbicide to weed tomatoes, and many weeds in the field, especially broadleaf weeds.
