Abstract

Research was conducted in 1990 through 1992 to examine the vegetative and reproductive growth regulating activity of imazaquin and AC 263,222 on common bermudagrass. AC 263,222 at 0.06 kg ha−1, alone and in combination with imazaquin (0.21 kg ai ha−1), significantly reduced seedhead number, seedhead height, and vegetative canopy height for a 4-wk period after both May and July treatment. Imazaquin (0.42 kg ai ha−1) applied alone resulted in less turfgrass discoloration, but suppressed vegetative and reproductive growth of common bermudagrass less as compared with treatments containing AC 263,222.
