| Abstract/Contents: | "Kentucky bluegrass (Poa pratensis L. 'Parade', 'Adelphi', 'Glade', and 'Rugby') and tall fescue (Festuca arundinacea Schreb. 'Kentucky 31') were treated in field experiments with chlorsulfuron. The objectives of the two experiments were to determine if this herbicide has the potential to be used for selective control of tall fescue in Kentucky bluegrass turf. Chlorsulfuron treatments included single rates of 0, 18, 35, 71, 141, 212, and 282 g ai/ha and split rates, applied 14 days apart, of 18 + 18, 35 + 35, 71 + 71, 141 + 141, and 212 + 212 g/ha. Clipping weights and turfgrass quality ratings were taken in both experiments. Kentucky bluegrass showed a higher tolerance to the chemical, with no decrease in turf quality at the highest single and split application rates in both experiments. However, as the chlorsulfuron rate increased, clipping weight decreaesd. Tall fescue showed a low tolerance to the chemical and was controlled at single rate of 71 g/ha and split rates of 71 + 71 g/ha, severe growth inhibition and discoloration of aboveground tisssue occurred at the lower rates. Twelve months after the first chlorsulfuron was applied in each experiment, glyphosate was sprayed over the plots to kill all existing plant material, and Kentucky bluegrass was seeded into the plots 2 weeks later at the rate of 0.75 kg/100 m2. There was no inhibition of bluegrass seed germination at any of the rates of chlorsulfuron." |
