| Abstract/Contents: | "This research was conducted at the Landscape Management Research Center, University Park, PA, on a mature Kentucky bluegrass (Poa pratensis L.) turf to assess whether perennial ryegrass (Lolium perenne L.) could be successfully overseeded in the spring where prodiamine was applied the previous fall. There were two randomized complete block design studies with three replications (plot size 3' x 10'). The preemergence treatments were applied on November 13, 1995 using a three ft hand held CO₂ powered boom sprayer with two 6504 flat fan nozzles calibrated to deliver 80 gpa and 30 psi and with a shaker jar for the prodiamine/fertilizer combinations. On May 13, 1996, one half of each plot was treated with glyphosate at a rate o 5 lb ai/A. On May 29, 1996, the killed area of each plot was verticut in three directions and the debris removed. The area was then overseeded at 5 lbs/1000ft₂] from a starter fertilizer. Both sites were maintained at 2 1/2" using a 21" walk behind rotary mower returning the clippings to the site and the site received irrigation as needed. In one study, prodiamine was applied at 0.5, 0.75 and 1.13 lbs ai/A. Control of crabgrass rated on 8/20/96 was 93, 95, and 95 percent, respectively. The percentage perennial ryegrass cover was 88, 80, and 75%, respectively for prodiamine rates, while the untreated control had 88% perennial ryegrass cover. Although a slight decrease in perennial ryegrass establishment was observed as the prodiamine rate increased, turf treated with the 0.75 rate (which is higher that recommended in Pennsylvania) still was similar in perennial ryegrass establishment to areas not receiving prodiamine treatment. In the second study, prodiamine was applied using four different fertilizer carriers at a rate of 0.75 lbs ai/A. Three of the four materials provided crabgrass control at 90% or better. THe nonprodiamine-treated, but overseeded, areas in this study had 83% perennial ryegrass cover. The fertilizer/prodiamine-treated areas all had very similar perennial ryegrass cover (within three percentage points of 75). It appears that fall-applied prodiamine (at recommended use rates) does not preclude successful overseeding with perennial ryegrass the following spring." |
