Abstract

In order to study the effect of different weed control methods, study was conducted in summer 2014 at the lawn situated in main campus of the University of Agriculture, Peshawar-Pakistan. Use of five methods comprised of five treatments including two mechanical methods (mowing and hand weeding), two herbicides {Harvester 50 EC (fluroxypyr + MCPA) and Bromoxynil 40 EC (bromoxynil + MCPA)} and a control treatment (weedy check). Data were collected on weed density m־², relative weed density, weed frequency, relative weed frequency and importance value indices of the weeds that infested the study area. Weed density was the highest (103.95 m־²) in the mowing treatment and lowest in Bromoxynil 40 EC (28.95 m-2). Herbicides treatments significantly affected weed density as compared to the rest of the treatments of hand weeding, mowing and weed check. Moreover, the performance of hand weeding treatment was also significantly more effective than the weedy check plots. It can be concluded that an integrated approach of combining cultural practices and chemicals can complement each other and give optimum results in weed management in turfs.
