抗性杂草现状

2024-06-17

除草剂抗性问题一直伴随着除草剂的使用和发展，挑战着除草剂的使用，也“激励”着除草剂的开发。

1、全球抗性杂草概况

经Weedscience网站统计，截止目前，全球共发现530个除草剂抗性案例。涉及272种杂草（其中155种双子叶、117种单子叶），168种除草剂（31个除草剂作用机制中占21个）；分布在72个国家，共100种作物田中。

截止2023年，各类作用机制的除草剂抗性杂草数量：抗乙酰乳酸合成酶（ALS）抑制剂除草剂的杂草数量最多，为174种；其次依次为光合系统Ⅱ（PSⅡ）抑制剂、烯醇丙酮莽草酸磷酸合成酶（EPSP）抑制剂、乙酰辅酶A羧化酶（ACCase）抑制剂、生长素类似物除草剂、光合系统Ⅰ（PSⅠ）电子转移除草剂、微管组装抑制剂，抗性杂草数量分别为87、59、51、44、33、12种。

而同一种杂草存在多个除草剂抗性的趋势也愈发严重。截止2020年，248种杂草对2种及2种以上作用机制的除草剂产生抗性，占比94.66%。对2-5种作用机制的除草剂产生抗性的杂草数量分别为104、54、32和19种。其中，硬直黑麦草和早熟禾对12种作用位点的除草剂已经产生抗性。

从统计数据可以看出，已产生抗性杂草最严重的科为禾本科。共92种抗性杂草；其他位列前10的抗性杂草科依次为菊科、十字花科、莎草科、苋科、蓼科、玄参科、泽泻科、藜科和石竹科。分布最多的作物田为小麦田，统计有85种杂草已产生抗性，其次为玉米田、水稻田、大豆田等。

莠去津、草甘膦和苯磺隆是抗性问题最严重的三个除草剂，分别已发现66、59和48种杂草对其产生抗药性。其次还有咪唑乙烟酸、甲氧咪草烟、甲基碘磺隆钠盐、甲磺隆、氯磺隆、精噁唑禾草灵、百草枯、苄嘧磺隆、西玛津、噻吩磺隆、啶磺草胺和甲基二磺隆。

2、我国抗性杂草概况

Weedscience网站统计了我国1990年-2023年报导的抗性杂草发生案例，共51个。主要发生的抗性杂草有日本看麦娘、反枝苋、稗草（原变种）、菵草、雨久花、野慈姑、播娘蒿、小飞蓬、猪殃殃、荠菜、麦家公、看麦娘、牛繁缕、鸭舌草、马唐、繁缕、牛筋草、硬草、千金子、铁苋菜、通泉草、稗草（西来稗变种）、棒头草、大巢菜、多花水苋菜、黑麦草、水稗。其中抗性较为严重的是稗草和日本看麦娘。

主要分布于小麦、冬小麦、水稻、棉花、玉米、大豆田及非耕地中。主要分布在水稻和小麦田中。

产生抗性较多的除草剂包括苯磺隆、苄嘧磺隆等ALS除草剂，及炔草酯、精噁唑禾草灵等ACCase除草剂。
