摘　　要：为评价安融乐与除草剂混用对小麦田恶性杂草多花黑麦草的防除效果,开展了田间试验。结果表明,安融乐可以提高除草剂的速效性。药后15 d, 5%唑啉草酯乳油用量减少300 mL/hm^(2)后,加入安融乐使多花黑麦草达到5级药害症状的比例增加55.56%~61.69%;安融乐与5%唑啉草酯乳油+50%异丙隆可湿性粉剂+18%氟唑磺隆·炔草酯可分散油悬浮剂混用达到5级药害症状的杂草比例比除草剂单用增加125.35%~141.95%;安融乐与5%唑啉草酯乳油+30 g/L甲基二磺隆可分散油悬浮剂+18%氟唑磺隆·炔草酯可分散油悬浮剂混用达到5级药害症状的杂草比例比除草剂单用增加21.42%~35.82%。药后45 d,杂草株防效和鲜重防效均达到最高。安融乐能有效提高除草剂对多花黑麦草的作用速度及防除效果,可以进一步示范和推广。A field experiment was conducted to evaluate the control effect of the mixture of AnnGro and herbicides on the malignant weed Lolium multiflorum in wheat fields.The results indicated that AnnGro could improve the quick efficacy of herbicides.At 15 days after a reduction of 300 mL/hm^(2) in the dosage of 5%imidacloprid EC,the addition of AnnGro increased the proportion of grade 5 pesticide damage symptoms in Lolium multiflorum by 55.56%-61.69%;the proportion of weeds with grade 5 pesticide damage symptoms achieved by the mixture of AnnGro and 5%imidacloprid EC+50%isoproturon wettable powder+18%fluazuron·ethyne ester dispersible oil suspension agent increased by 125.35%-141.95%compared to the single use of herbicides;the proportion of weeds with grade 5 pesticide damage symptoms achieved by mixing AnnGro with 5%imidacloprid EC+30 g/L methyldisulfuron dispersible oil suspension agent+18%fluazuron·ethyne ester dispersible oil suspension agent increased by 21.42%-35.82%compared to using herbicides alone.After 45 days of treatment,the weed control effect and fresh weight control effect reached the highest.AnnGro could effectively improve the rate of action and control effect of herbicides on Lolium multiflorum,and could be further demonstrated and promoted.
