Improving herbicides efficacy of Topik and Traxos on wheat plants and associated weeds by adjuvants

Abstract: Abstract: Two field experiments were carried out during winter seasons of 2008/2009 and 2009/2010 at the Experimental Station of Agricultural Research Center, El-Serw Station Damietta Governorate, Egypt to study the effect of additives on the efficacy of Topik (Clodinafop-propargyl) and Traxos (Pinoxadin+Clodinafop+Safener) herbicides (with or without Arkopal N100) on weeds and wheat plants. The results indicated that all weed control treatments significantly reduced fresh, dry weight and caused significant increases in photosynthetic pigments after 75 days from sowing, yield, yield attributes and grain protein percent. In addition anatomical structure is a significant leaf dysfunction constitutes a part of the killing action of the specific herbicide on target weeds. Traxos at 500 cm3 tank-mixed with Arkopal N100 at 4 and 8 % followed by Topik at 140g tank-mixed with adjuvant at 4%, Traxos at 375 cm3 tank-mixed with adjuvant at 8%, Topik at 140 and 105g tank-mixed with adjuvant at 8%, Traxos at 375 cm3 and Topik at 126 g tank-mixed with adjuvant at 4% treatments, respectively recorded the highest reduction of weeds and recorded the highest values of photosynthetic concentrations as well as, increased significantly produced higher number of spike/ m2, grain yield , straw yield, crop index and grain protein % when compared with unweeded control in both seasons. On the other side, the lowest effective on the other self characters were by using Traxos at 500 cm3 alone and Topik at 140g alone and hand weeding twice at 30 and 45 days after sowing respectively gave less effective when compared with all other treatments and unweeded control in both seasons. While, a non significant effect due to weed control treatments 1000 grain weight, phosphorus and potassium percentage in grain .
