Experiment on 75% Pyrfluoroyl·Isopropanone·Zolinegrass to Control Annual Weeds in Winter Wheat Fields
[Objective]To investigate the comprehensive control effect of a multi compound herbicide 75%pyrfluoroyl·isopropanone·zolinegrass(trade name"Bocao")on annual weeds in winter wheat fields.[Method]Experimental research was conducted on the control effects of wheat weeds which have a high incidence in winter in the wheat fields of Guohe town,as well as broad-leaved weed clusters,the optimal dosage of herbicides,and the safety of herbicides on wheat after application.[Result]After 45 days of treatment,the best weed control effect was achieved when a mixture of 75%pyrfluoroyl·isopropanone·zolinegrass 1 200 g/hm2 and 50%isopropanone 1 500 g/hm2 was used,and it was safe for wheat growth.[Conclusion]The results provide technical basis for farmers to control annual weeds in wheat fields.
