Abstract/Contents: | Four growth retardants (mefluidide, MBR 18337, EL 500, and PP 333) were applied to Merion and Pennstar Kentucky bluegrasses to assess the growth retarding capability and phytotoxicity. Color, height, weight, seed inhibition, density, and soil moisture levels were measured. PP 333 and EL 500 were slower acting, but were ultimately more effective in reducing growth of both bluegrasses. All treatments that caused significant growth suppression also caused some discoloration. MBR 18377 and mefluidide were significantly more effective in inhibiting seedheads than either PP 333 of EL 500, but the latter two reduced culm length. Density, assessed approximately one year after treatment, was not reduced by any of the treatments. Some increase in density was found for turf treated with the 3.36 kg/ha rate of EL 500 (both formulations) and the 4.48 kg/ha rate of PP 333. The soil moisture percentage was also highest for these treatments. |
