| Abstract/Contents: | "Field research was conducted to evaluate plant growth regulator (PGR) applications through application placement technologies in which pesticides are placed directly onto cut surfaces of plants during a mowing operation. Specially designed mowers equipped with a fluid application system allow for low-volume PGR application from the mower blades allowing mowing and pesticide applications to be completed in a single pass. A wet-blade, wick-type, and broadcast sprayer were used to apply imazapic at three rates (8.8, 35.1, and 52.6 g ai/ha), and melfluidide + chlorsulfuron tank mix at 6.6 + 140.2 g ai/ha. Studies were conducted on tall fescue roadsides during a two-year period (2003 and 2004). Application placement equipment did not improve PGR efficacy when compared to a foliar broadcast spray. Tall fescue was slightly injured and discolored by all treatments , but recovered by one month after treatment. Imazapic at 52.6 g ai/ha suppressed plant growth for three months after treatment compared to the nontreated (17cm of growth) when applied with the wick application and broadcast sprayer (6.8 and 2.5 cm respectively). When compared with nonmowed treatments, all treatments applied with the wet-blade failed to cause a reduction in tall fescue growth. In 2003, seedheads were completely suppressed by all treatments throughout the study. Seedheads were not completely suppressed in 2004, ranging from 76 to 100% reduction of seedheads when compared to the nontreated with the lowest rate of imazapic applied with the wet-blade machine providing the lowest seedhead control." |
