Abstract

2, 4D 0.5 kg/ha, metsulfuronmethyl 3 g/ha and carfentrazone 10 g/ha each immediately after and 2, 4 and 6 days after clodinafop 60 g/ha were compared to clodinafop alone and untreated check for control of weeds in wheat. Phalaris minor, Avena ludoviciana, Poa annua, Vicia sativa, Anagallis arvensis, Ranunculus arvensis and Coronopus didymus were the important weeds associated with wheat crop. All herbicidal treatments were significantly superior to untreated check in reducing P. minor, Poa annua and A. ludoviciana. Except 2, 4D and carfentrazone immediately after clodinafop, all herbicides completely killed Phalaris minor. 2,4D four days after and metsulfuron immediately after clodinafop gave significantly lower count of V. sativa during 200506 and 200607, respectively. All treatments except clodinafop alone were superior to weedy check in suppressing A. arvensis and R. arvensis. All treatments controlled C. didymus effectively. Application of 2, 4D four days after clodinafop gave maximum yield. However, all other treatments except 2, 4D two days after metsulfuron six days after and carfentrazone four days after clodinafop during 2005 were at par with 2,4D four days after clodinafop. Weeds reduced wheat grain yield by 38.8%.
