Abstract/Contents: | The preventative necrotic ring spot (Leptospheria korrae) trials #1 and #2 were conducted on irrigated, fertilized, Kentucky bluegrass residential lawns. The applications for study #1 started on May 12 and June 13 and study #2 started on May 19 and June 17. They were 3 replications of a random block design, using a 6'x 9' plot size, with additional applications after 2 weeks. Turf recovery was disappointing, likely because of the drought and the severe phosphorous levels, despite the use of a complete maintenance fertilizer. The table lists 61 treatments, the control, application rates, application intervals, observations, dates observed, and statistical significance. The second study was the same design, and location except that study #1 was evaluated by the number of patches/plot and Study #2 was evaluated by percent area of infected turf/plot. The table list 50 treatments, the control, application rates, application interval, ratings, statistical significance, and descriptive notes. No phytotoxicity was observed in either study at the times the ratings were taken. |
