随着我国麦田除草剂长期大量被使用,麦田杂草对除草剂的敏感性也在发生着微妙的变化,不同地区的杂草耐药性也在变化着,麦田主要杂草耐药性问题不容乐观。据了解,麦田主要阔叶杂草有播娘蒿、荠菜、猪殃殃、泽漆、牛繁缕、麦瓶草、佛座、刺儿菜、麦家公、波斯婆婆纳等。首先,播娘蒿和荠菜是目前大部分地区公认的产生抗性的杂草,对苯磺隆、苄嘧磺隆及其组合的耐药性均比较强,可以说完全没有效果。对氯氟吡氧乙酸异辛酯、双氟磺草
With the large amount of wheat field herbicides being used in China for a long time, the sensitivity of weeds to herbicides in wheat fields is also undergoing subtle changes. The weed resistance in different areas is also changing. The major weed resistance problems in wheat fields can not be tolerated optimism. It is understood that the main broadleaf weeds wheat sowing Artemisia annua, Shepherd ’s Purse, Galium aparine, Ze paint, Niu Mu, Cordyceps, Buddha seat, Calendula vegetables, wheat family, Persian grandmother and so on.
