| Abstract/Contents: | Briefly describes problems that Poa annua seeding can cause on the golf course. Discusses the use of plant growth regulators and herbicides to inhibit Poa annua seeding. States that phytotoxicity is a concern in using Embark (mefluidide) to supress Poa annua seedhead and that some golf course superintendents "were using the wetting agent Aqua-Gro L to good effect, with more variable results but somewhat lessened phytotoxicity concerns." Describes how the author "decided to try an onsite test to see if Aqua-Gro could consistently suppress seedheads compared to Embark. Also, I [the author] had heard that ethephon (Proxy) had shown good activity for Poa annua seedhead suppression in 1999 trials and should be included in the study." Results include that "only Proxy and Embark provided that [effective] level of seedhead suppression in May 2000" and "wetting agent treatments showed little seedhead suppression, with the exception of the 8+4+4 fl. oz. Aqua-Gro regime at Fox Valley." States that "all of the products tested can cause yellowing or tip burn on fine turf under the right/wrong conditions" and that Embark and Proxy "showed the highest levels of discoloration and thinning on turf." States that "there is good evidence that tank-mixing chelated iron or using follow-up Fe treatments will 'safen' or counteract the damage caused by Embark, and possibly Proxy. Suggests that "if you want to try Embark or Proxy for seedhead suppression, be aware of possible phytotoxicity, treat small test areas or the chipping green first and include some chelated Fe." |
