Influence of Terbutryn and Flufenacet on Indoor Activity and Safety of Grassy Weeds in Wheat Fields
Soil sealing tests were conducted to evaluate the herbicidal activity of terbutryn and flufenacet with different proportions for grassy weeds in wheat fields and their ability to ensure wheat safety.The results show that when 50%terbutryn SC and 41%flufenacet are mixed in a ratio of 6∶1,which is then applied at a dosage of 2 800 g a.i./hm2,it achieves a 100%inhibition effect on Annual ryegrass,Shortawn foxtail,and Annual bluegrass,with an inhibition rate of 99.01%for Beckmannia syzigachne and an inhibition rate of 87.11%for Aegilops tauschii Coss.In addition,it shows no significant impact on the growth of wheat seedlings.The combination of terbutryn and flufenacet not only broadens the spectrum of weed control but also enhances the control of Aegilops tauschii Coss.with resistance to drugs in wheat fields.It reduces the amount of chemical agents used in the field and is an excellent wheat herbicide for ensuring wheat safety.
