| 中文摘要: |
| 吡啶甲酸类除草剂属合成激素类, 目前登记使用的有效成分包括氨氯吡啶酸、二氯吡啶酸和氯氨吡啶酸, 分别于1963年、1977年和2005年上市, 主要用于阔叶杂草和灌木的茎叶处理防控, 其中氯氨吡啶酸具有土壤封闭活性。吡啶甲酸类除草剂的作用靶标仍未明确, 有可能来自生长素结合蛋白家族。全世界报道的抗吡啶甲酸类除草剂杂草共涉及7种8个生物型。目前, 我国登记的除草剂品种中共有13个复配剂含氨氯吡啶酸和二氯吡啶酸, 1个含氨氯吡啶酸、氯氨吡啶酸和二氯吡啶酸;国外登记的吡啶甲酸类除草剂复配剂主要为与其他激素型除草剂、ALS(乙酰乳酸合酶)抑制剂、ACCase(乙酰辅酶A羧化酶)抑制剂的组合。该类除草剂仍然具有较好的应用前景, 在主要应用场景下常见杂草对氨氯吡啶酸、二氯吡啶酸、氯氨吡啶酸的敏感性仍需系统研究, 该类除草剂主要靶标杂草种群的抗药性水平也亟须检测。 |
| 英文摘要: |
| Pyridinecarboxylic acids are a group of synthetic auxin herbicides. To date, there are three effective ingredients, picloram, clopyralid, and aminopyralid were registered, and introduced to the market in 1963, 1977, and 2005 respectively, mainly for the prevention and control of broadleaf weeds or shrubs. Among them aminopyralid also has soil sealing activity. The accurate action targets of pyridinecarboxylic acid herbicides are still unclear, although the auxin-binding protein family is a possible candidate. Seven weed species with eight biotypes were reported to hold resistance to pyridinecarboxylic acid herbicides all over the world. In China, there are 13 registered herbicide formulations containing picloram and clopyralid, and one formulation containing picloram, aminopyralid, and clopyralid. And pyridinecarboxylic acid herbicides are frequently mixed with other hormone herbicides, ALS (acetolactate synthase) inhibitors or ACCase (acetyl-CoA carboxylase) inhibitors in the herbicides registered abroad. Pyridinecarboxylic acid herbicides still have good market potential for weed management practice worldwide, but the sensitivities of common weeds populations to picloram, clopyralid, and aminopyralid should be systematically tested and resistance level of the main target weed species to these herbicides are also needs to be tested. |
