Wheat is a worldwide significant crop. Roughly one-sixth of the total fertile land in the world is cultivated with wheat crops. It supplies about 25% of the food calories for the world’s growing population. Wheat crops are infested with several weeds namely Phalaris minor, Chenopodium ablum, Anagallis arvensis, convolvulus arvensis, etc. Phalaris minor Linn (Canary grass) and Avena fatua (Wild oat) is the primary concern in a large area of the North-western plain zone. Weed management is indispensable for increasing crop production under such circumstances, Judicious use of herbicides is the only suitable way for effective and economical weed control. Numerous post-emergence herbicides are available globally to control weeds in wheat crops that cause plant death by affecting protein or RNA biosynthesis. Post-emergence application of sulfosulfuron against Phalaris minor provided a 25% wheat yield compared to the weedy check. The data from the study revealed that the significant maximum number of grains/ ear head (62.17) was recorded with the application of Carfentrazone ethyl 5% + clodinafop propargyl 15% DF 620g/ha, which was closely followed by under the treatment of Carfentrazone ethyl 5% + clodinafop propargyl 15% DF 300g/ha (42.13) and Carfentrazone ethyl 5% + clodinafop propargyl 15% DF 800g/ha (61.98). The significantly minimum number of grains/earhead (57.59) was recorded in weedy check plot.
