Weed management studies were initiated in wheat on farmers' fields at 3locations in the command area of Dir Area Support Program (DASP) during2000-01 and 2001-02. Three treatments were employed in the studies viz. handweeded check, herbicide Buctril-M and the unweeded check. Under the mostinfested site i.e. Ajoo Talash about 8 times higher density of weeds wasrecorded in the two years of studies in the weedy check treated plots vs.Buctril-M. During 2000-01, as compared to the weedy check 12 to 74.64%increase in grain yield at 3 locations was recorded due to the application ofBuctril-M. While, the hand weeding increased grain yield to the tune of 3 to41% over the weedy check. A very lucrative cost effective gain was recordeddue to the application of Buctril-M. The ratio oscillated between 2.23 and 7.8at the three locations. However, for the hand weeded plots the gain in yieldwas nullified with the additional cost on weeding, thus only a slight increaseat Ajoo and Chokytan was recorded, while a severe loss was observed atSamar Bagh. During the subsequent year of study the gain in grain yield dueto the application of Buctril-M was less wider ranging between 10 and 29% at3 locations of studies. However, the cost: benefit ratio was still attractive dueto herbicide application varying 1:2 and 1:5.2. The added advantage due tohand weeding was again lower as compared to herbicide use. Thus, theherbicide Buctril-M is recommended for the management of broadleaf weeds inwheat in the area of study.
