| Abstract/Contents: | "A series of experimental and commercially available preemergence herbicides were applied to a Kentucky bluegrass turf on a golf course fairway in the 1982 season. The experimentals included oxadiazon formulated as a 50% wettable powder, oxadiazon in the Pel-Tech formulation, DCPA 6 (a flowable formulation of DCPA), ANDG-1-82, and benefin in a Pel-Tech 20 formulation. The commercially available materials included granular oxadiazon, benefin in a Pel-Tech 10 formulations, DCPA W-75, benefin granular, and betasan 4E. Evaluations of phytotoxicity were made 8, 12, and 35 days after application. Visible damage was observed on plots treated with oxadiazon 50% WP and ANDG-1-82 at 8 and 12 days. By the 35th day, only plots treated with oxadiazon 50% WP showed visible damage. Effective crabgrass control was obtained with all rates of oxadiazon above 1.12 kh/ha. The benefin Pel-Tech 20 was not effective at a single application rate of 2.24 kg/ha, however, crabgrass was effectively controlled by this material in split applications 2.24 kg/ha followed 5 wks later by 1.68 kg/ha. Plots treated with ANDG-1-82 showed an increase in crabgrass population over the control. This was attributed to a noticeable growth retarding the effect of this material on the Kentucky bluegrass, which reduced the competitive advantage of this species over the crabgrass early in the season. DCPA was an effective crabgrass control at all rates tested." |
