Weed infestation is a serious problem for crop yield. It causes a huge yield loss. A comprehensive study to investigate the main wheat weeds within Tehsil Pharpur (Dhakki, Headbilot, Dhupsari, Malakheil, Kalapani, Laar, Rakh Bandkura) in the Dera Ismail Khan region was conducted during the 2020-21 harvest. About 21 species were collected and the weeds competed with the wheat crop for nutrients, water, and light and disrupted the wheat crop. Data was collected in a weed growth phase and a quadratic method was used. Homophobic (RD), relative frequency (RF), relative coefficient (RCC), and value index (IVI) were recorded. It was determined that the most problematic weeds in this area were Chenopodium album, Medicago polymorpha, Lathyrus aphaca, Rumex dentatus, Polygonum plebeium, Mazus japonicus, Oxallis corniculata, Fumaria indica, Sonchus asper, Emex spinose, Galium aparine, Melilotus parviflora, Anagallis arvensis, Viccia sativa, Euphorbia helioscopia, Chenopodium murale, Launea procumbens, Phyllanthus maderaspatensis, Scirpus maritimus, Beta maritima.
