Abstract
Parthenium hysterophorus L., is a noxious annual weed rapidly spreading across the non-cropped areas of the Khyber Pakhtunkhwa (KP) province and elsewhere in Pakistan. Parthenium weed has attained the status of most frequently and densely occurring weed in Swabi, Mardan and Charsadda districts while it is present in Peshawar district in isolated infestations. Parthenium weed has become a major threat to grazing land, roadside, wasteland, wetland, as well as cultivated land in KP province. Field experiments were conducted to evaluate the efficacy of different herbicides against parthenium weed at different growth stages in non-cropped area of Charsadda District, KP-Pakistan during summer 2009 and 2010. The experiments were laid out in RCBD, replicated four times separately for each growth stage with ten treatments. Herbicides used in the experiments were Aatrax (atrazine) @ 1.0, Buctril Super 60 EC (bromoxynil+MCPA) @ 0.80, Round Up (glyphosate) @ 4.0, Dual Gold 960 EC (S-metolachlor) @ 1.92
