| Abstract/Contents: | "Field trials were conducted in 2000 and 2001 in North Brunswick, NJ to determine the potential of converting pure stands of annual bluegrass (Poa annua L. ssp. annua) to bentgrass. The parameters evaluated include three overseeding dates, four bentgrass varieties, and four growth regulator programs. In 2000 the overseeding dates were July 1, August 18, and September 18. In 2001 the overseeding dates were June 27, August 17, and September 17. Three creeping bentgrass (Agrostis palustris) varieties, 'Penncross', 'L-93', and 'Penn A-4'; and one velvet bentgrass (Agrostis canina); 'SR-7200' were evaluated. Growth regulator treatments prior to overseeding included; no treatment, one application of 0.1 lbs ai/A of trinexapac-ethyl 7 days before overseeding, one application of 0.6 lbs ai/A of paclobutrazol 14 days before overseeding, an untreated check. All treatments, except the untreated check, received sequential applications of trinexapac-ethyl at 0.1 lbs ai/A initiated one month after the overseeding and continuing into the late fall. The Poa annua stand was established in the fall of 1999 by seeding 65.34 lbs/A and maintained at a height of 0.125 in. Each block was aerated, topdressed, and verticut to prepare a seed bed. In 2000 the July 1st overseeding date showed the greatest establishment of the three. 'SR-7200' velvet bentgrass has shown the greatest establishment across all overseeding dates and growth regulator programs followed by 'Penn A-4', 'L-93', and lastly 'Penncross'. On 7/12/2001 percent bentgrass coverage in the July 1st overseeding averaged across growth regulator programs was 74 percent for 'SR-7200', 47 percent for 'Penn A-4' and 'L-93', and 9 percent for 'Penncross'. In contrast, percent bentgrass coverage in the August 18th overseeding was 29 percent for 'SR-7200' and <10 percent for each of the other three varieties. None of the growth regulation programs showed a significant increase in the establishment of the overseeded bentgrass varieties. Results from the 2000 study suggest that newer, more aggressive bentgrass varieties, such as 'Penn A-4', 'L-93', and 'SR-7200', can establish quicker and maintain a higher degree of vigor in the presence of Poa annua when overseeding in early summer. This study is currently being duplicated in 2001." |
