Abstract:
An experiment was conducted at Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya to study the “Effect of various herbicide to control weeds in wheat (Triticumaestivum L.)” during rabi seasons of 2014 to 2015 in randomized block design with three replications. The experiment comprised of twelve treatments of weed management viz.,T1-Pendimethalin @ 0.75 kg ha-1, T2-Sulfosulfuron @ 0.025 kg ha-1, T3-Metribuzin @ 0.21 kg ha-1, T4-Clodinafop @ 0.06 kg ha-1, T5-Pendimethalin+metribuzin @ 1.0+0.175 kg ha-1, T6-Pendimethalin fbsulfosulfuron @ 1.0+0.018 kg ha-1, T7- Sulfosulfuron+metsulfuron (Total) @ 0.03+0.002 kg ha-1, T8- Pinoxaden+ metsulfuron (Premix) @ 0.06+0.004 kg ha-1, T9-Mesoulfuron+ iodosulfuron (Atlantis) @ 0.012+0.0024 kg ha-1, T10- Clodinafop+metsulfuron (Vesta) @ 0.06+0.004 kg ha-1, T11-Weed free, T12-un-weeded control.Wheat (Triticumaestivum L.) is staple food of the world and falls under poaceae family. Weeds are considered as one of the major constraints in wheat cultivation. The prominent weeds noted in wheat fields are Phalaris minor, Chenopodium album, Anagallisarvensis, Avenafatua, Convolvulus arvensis, Lathyrusaphaca, Cyperusrotundus and Cynodondactylon etc. application of Pendimethalin+metribuzin @ 1.0+0.175 kg ha-1 has been found most effective to control the weeds as compared to other herbicide at all the stages. Post emergence application of Pendimethalinfbsulfosulfuron @ 1.0+0.018 kg ha-1 was found at par with most effective to control the weeds followed by post emergence application of Sulfosulfuron+metsulfuron (Total) @ 0.03+0.002 kg ha-1and both were significantly superior than weedy check. Pre emergence application of Pendimethalin+metribuzin @ 1.0+0.175 kg ha-1 was most effective to reduce the weed dry weight g m-2 which remained at par with Post emergence application of Pendimethalinfbsulfosulfuron @ 1.0+0.018 kg ha-1 and weed free. Application of Pendimethalin+metribuzin @ 1.0+0.175 kg ha-1 provided the highest weed control efficiency (93.33%) followed by Post emergence Application of Pendimethalinfbsulfosulfuron @ 1.0+0.018 kg ha-1 (92.23%). This was mainly due to lowest weed dry weight under the effects of above treatment
