| Abstract/Contents: | "Several herbicides and plant growth regulators (PGRs) were evaluated alone and in various combinations for use in Kentucky bluegrass (Poa pratensis L. a mixture of 'Glade', 'Columbia' and 'Merit'), tall fescue (Festuca arundinacea Schreb. 'Rebel II'), and perennial ryegrass (Lolium perenne L, 'Palmer'). Treatments were applied on May 12, 1989 at the Adelphia Research Center, Adelphia, NJ. A CO2- propelled backpack sprayer was used with water as the carrier. The experimental design for each turfgrass species was a randomized complete block with three replications. Materials included in the study were herbicides: BAS-514, CGA 136872, and triasulfuron; and PGRs: amidchlor, CGA 163935, a combination of imazethapyr & imazapyr (27:1), maleic hydrazide, melfluidide, and paclobutrazol. The herbicides were evaluated for PGR activity as well as for general weed control. Data collected were weekly heights, seedhead counts, weed control ratings, turf grass quality ratings, and clipping weights. Treatments were applied after complete turfgrass green-up, and no injury to the tall fescue was observed. In the Kentucky bluegrass and perennial ryegrass however, some treatments resulted in slight turf discoloration. This was particularly noticeable with imazethapyr & imazapyr at 0.128 kg/ha, and with the combination treatments: triasulfuron + CGA 163935 at 0.045 + 0.78 kg/ha, respectively, and CGA163935 + (imazethapyr & imazapyr) at 0.4 + 0.114 kg/ha, respectively. Suppression of turfgrass heights and seedhead emergence were exceptional for several treatments. Six weeks following treatment, height suppression was still evident by triasulfuron + CGS 163935 at 0.045 + 0.78 kg/ha, respectively, and CGA 163935 + (imazethapyr and imazapyr) at 0.4 + 0.114 kg/ha, respectively, by more than 50% in the Kentucky bluegrass and tall fescue, and by more than 60% in the ryegrass." |
