[Objective] The aim of the research was to control all kinds of weeds in wheat field better.
[Method] Four treatments of compounding 48% Dicamba,72% 2.4-d butylate and clean water(as CK) were set up to study the control effects of compounding 2,4-d butylate and Dicamba on weeds in wheat field.[Result] When the compound of 2,4-d butylate and Dicamba was sprayed for 15 d, its control effect reached 59.7% for each plant and it reached 73.8% after 30 d. When the drugs were used for 15 d, the control effects of Dicamba and 2.4-d butylate were 56.6% and 54.7% resp. and their control effects were 66.2% and 69.3% resp. after 30 d. When the drugs were used for 45 d, their control effects of compounding 2.4-d butylate and Dicamba on the fresh weight of Eqisetrm arvense L.,Herba hypecoi,Lepyrodiclis holosteoides,Thlaspi arvense L. and Calium aparine were 70.6%, 71.5%,69.2%,65.3% and 67.8% resp. The yield increasing rate of compounding 2,4-d butylate and Dicamba was highest and reached 19.2% .
[Conclusion] The control effect of compounding 2.4-D butylate and Dicamba on weeds in wheat field was better and it had the popularization value in the field production
