| Abstract/Contents: | "A study was conducted on overseeded common bermudagrass fairways to determine the optimal rate, application timing and frequency of application for Primo to achieve improved Fall transition from common bermudagrass to ryegrass, and improved transition the following Spring, from ryegrass to bermudagrass. Of the 41 treatments tested (4 rates, 5 timing strategies and single vs. double applications), we found that Primo treatments made at the time of the first ryegrass mowing (on 10/23/96, or 1 day after the first mowing) resulted in an improved Fall transition from bermudagrass to ryegrass and significantly higher quality ryegrass during the critical winter and spring months than other treatments tested. The most economical of the highest ranked treatments was a single application of Primo Liquid at 0.5 oz/1000 sq ft, applied on 10/23/96. In contrast, Primo applications made later in the Fall (10/30/96, or 8 days after the first mow), produced a negative effect on turf quality during the 1997 Spring transition. These results confirm that the currently labeled rate of 0.5 oz/1000 square feet for use of Primo Liquid in overseeding programs is the optimal rate for use in overseeding programs in the Low Desert, but that the currently recommended application timing (1 - 5 days before overseeding) may need to be adjusted. To confirm the results of this study, a 1997/98 trial that re-tests the highest ranked treatments from this year's study is recommended for initiation in September, 1997." |
