Abstract/Contents:"Various products are being used at low and frequent doses in an attempt to convert a fairway turf that is predominately Poa annua to predominately creeping bentgrass. The study was initiated in the summer of 1989 and continues to date on the 18 fairway of the Toftrees Resort, State College, PA. Treatments were first applied on July 17, 1989. Total amounts of active ingredient applied before initial ratings appear in Table 1. Sprayed applications were made with a 3-point hitch, PTO powered sprayer delivering 50 gal/a. Granular applications were applied with a 30 in Gandy drop spreader. The study area was overseeded with Penncross creeping bentgrass (Agrostis palustris) on August 31, 1990, at 0.5 lbs/1000 sq ft. Cutless 50WP at 1.25 lbs ai/acre/year and TGR at 1.25 lbs ai/acre/year had the highest percentages of bentgrass for the May 8, 1990 rating. The other Cutless treatments (1.0 and 1.0+fert lbs ai/acre/year) also greatly increased the amount of bentgrass."
