Studying the Effect of Mixing Herbicides and Microelcments on Weeds Control and Yield of Wheat

A field experiment was conducted in 2005-2006 at the Experimental Field orAzad Islamic University, Ahwaz unit, to study the efficacy of tank mixed application of herbicides and microelements und their effect on weed control and wheat yield. "j he experimental design was on J randomized complete block with four replications. Treatments consisted of Clodinafop-propergyl, Tribenuron-mcthyl. mixture or Clodinafop-propargyl and Tribenuron-methyl and mixture of these herbicides \\ ith complete microelement (7n, Cu. Fe, Mn, Mg, Mo) at I Kg"ha and Zink at 0/5 K~/hn. Results show that there is no significant different in weed control, which shows Clodirmfoppropargyl and Tribenuron-methyl were nicely intermixable with microelements. Thi~ mixture could control broad leaf and grass weeds with 99.55 percent and yielded 441 I) kʹU/ha wheat grain. Clodinatop-propargyl. Tribenuron-merhyl ami mixture of them were nicely intermixable. The best treatment was lank. rni..xed application of Clodiuafopprnpargyl, Tribenuron-metlryl and complete microelemeru which resulted in 99.71 percent weed control and 5480 l~/ha grain yield. So mixture application of herbicides and microelernents that used in this research can raised the wheal yield and control weeds.
