Abstract/Contents: | Presents a study "to evaluate selected herbicides and growth regulators for the seedhead suppression of Poa annua." Results include "Embark T&O treated Poa annua had a 90% seedhead suppresion rating on May 17. The best seedhead suppression for Poa annua treated with Proxy was found when the highest application rate (10 oz/M) was used (two applications 21 days apart). Some seedhead suppression was attained via applications of Prograss at low rates, but multiple applications...at (1.5 oz/M) appeared to be the best use of Prograss for seedhead suppression. When the rate was increased to 3 oz/M, seedhead suppression improved, but even for the single application unacceptable phytotoxicity was recorded on May 17. By making two applications at 3 oz/M, a slight increase in suppression occurred, but phytotoxicity was much more severe. Reducing the rate of the second application to 1.5 oz/M did not signficantly reduce phytotoxicity and had minimal impact on seedhead suppression. It appears that the industry standard (Embark T&O) can provide excellent seedhead suppression without causing unacceptable phytotoxicity." |
