Study on the Control Effect of Mixing AnnGro and Herbicides on Lolium multiflorum in Wheat Fields
A field experiment was conducted to evaluate the control effect of the mixture of AnnGro and herbicides on the malignant weed Loli-um 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/hm2 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 Loli-um multiflorum,and could be further demonstrated and promoted.
