| 摘 要： | 为了系统研究多花黑麦草、早熟禾、碱茅和棒头草等4种小麦田禾本科杂草的防除药剂活性,在温室内采用盆栽法研究了8种除草剂对小麦田多花黑麦草等4种禾本科杂草的生物活性。结果表明,乙酰乳酸合成酶(ALS)抑制剂啶磺草胺对早熟禾有很好的防除效果,田间推荐剂量下防效达到93.06%(防效均为田间推荐剂量下,下同),对碱茅、多花黑麦草和棒头草的效果也较好,防效在82.82%~86.89%之间,另2种ALS抑制剂氟唑磺隆和甲基二磺隆对早熟禾的防效较好,在61.27%~86.71%之间,但对其他3种杂草碱茅、棒头草和多花黑麦草的防效很差,防效仅在10.47%~29.43%之间。乙酰辅酶A羧化酶(ACCase)抑制剂唑啉草酯、肟草酮和炔草酯对碱茅、棒头草和多花黑麦草的防效均较好,在85.41%~100.00%之间,但对早熟禾的防效均较差,在19.08%~60.69%之间;另一种ACC抑制剂精噁唑禾草灵对棒头草防效为99.60%,对碱茅和多花黑麦草防效分别为72.00%和55.00%,对早熟禾仅为16.18%;植物光合系统Ⅱ抑制剂异丙隆对早熟禾、棒头草和碱茅的防效均较好,田间推荐剂量下防效在88.15%~96.53%之间,对多花黑麦草的效果略差,为67.43%。

| Abstract: | Pyroxsulam, flucarbazone-Na, pinoxaden, tralkoxydim and clodinafop-propargyl are newly registered herbicides in China. A glasshouse experiment was conducted to evaluate the efficacy of these herbicides, compared with several commonly used herbicides, on four grass weed species in wheat fields. Key results were: 1) The acetolactate synthase (ALS) inhibiting herbicide pyroxsulam achieved 93.06% control on Poa annua and 82.82%-86.89% control on Puccinellia distans, Lolium multiflorum, Polypogon fugax (all herbicides applied at recommended field dose rates). 2) Other ALS inhibiting herbicides flucarbazone-Na and mesosulfuron-methyl achieved 61.27%-86.71% control on P. annua, but only 10.47%-29.43% control of P. distans, L. multiflorum and P. fugax. 3) In contrast, the acetyl coenzyme A carboxylase (ACCase) inhibiting herbicides pinoxaden, tralkoxydim and clodinafop-propargyl showed 85.41%-100.00% control on P. distans, L. multiflorum and P. fugax, and 19.08%-60.69% on P. annua. 4) The other ACCase inhibiting herbicide fenoxaprop-p-ethyl showed 99.60% control of P. fugax, 72.00% and 55.00% of P. distans and L. multiflorum, and 16.18% control of P. annua. 5) The plant photosystem Ⅱ inhibiting herbicide isoproturon also controlled P. annua, P. distans and P. fugax (88.15%-96.53% control), but showed poorer control of L. multiflorum (67.43%). |
