Popis:	A 3-yr field study was conducted to determine the influence of N level (98 and 196 kg ha -1 yr -1 ), mowing height (3.2, 5.5, and 8.8 cm), and three herbicides on weed encroachment and overall quality of tall fescue Festuca arundinacea Schreb. cv. Rebel II. The major objective of this study was to identify cultural methods of excluding weed development in tall fescue. Dithiopyr [3, 5-pyridinedicarbothioic acid, 2-(difluoromethyl)-4-(2-methylpropyl)-6-(trifluoremethyl)-S, S-dimethylester] and pendimethalin [N-(1-ethylpropyl)-3, 4-dimethyl-2, 6-dinitrobenzenamine] were applied preemergence for smooth crabgrass [Digitaria ischaemum (Schreber) Schreber ex Muhlenb.] control, and fenoxaprop [(±)-2-[4-[(6-chloro-2-benzoxazolyl)oxy]- phenoxy] propanoic acid] was applied postemergence for crabgrass control (.)
