摘要
采用田间药效试验方法,研究了增效酮梨与22%氯吡·苯·唑草可湿性粉剂、20%氯氟吡氧乙酸乳油2种除草剂混用对小麦田阔叶杂草的防除效果.结果表明,2种除草剂与供试增效剂混用可有效防除小麦田常见阔叶杂草.药后30 d,各药剂处理对杂草防除效果最高,其中22%氯吡·苯·唑草可湿性粉剂加增效酮梨防效可达90.99%,药后45 d鲜质量防效最高可达95.25%.2种除草剂的使用可提高小麦产量.
Using field efficacy test,the control effectson the broad-leaved weeds in wheat fieldswere studied with two herbicides(22%clopyr,benzine,carfentrazone wettable powder and 20%fluroxypyr emulsifiable concentrate)mixed with one synergistic agent(synergistic ketone pear),respectively.The results showed that the two herbicides mixed with the synergistic agent can effectively control the broad-leaved weeds in wheat fields.It was 30 days after the treatment that the control effects on weeds reached the highest in both treatments.Moreover,the control effect oftreatment(22%clopyr,benzine,carfentrazone wettable powder together with synergistic ketone pear)could reach 90.99%.45 days after the medicine,the control effects on the fresh quality of weeds could reach 95.25%.The use of two herbicides can increase wheat yield.
