Abstract/Contents:"A growth retardant for turfgrass to reduce height, seedhead production and frequency of mowing without reducing aesthetic qualities of the turf could save labor and energy costs. Field tests were conducted in 1981 to determine whether DPX-6376 used alone and in combination with DPX-5648 (Oust) could effectively retard growth of common bermudagrass turf. In late June a uniform, weed-free common bermudagrass stand was sprayed with DPX-6376 at 17, 35, 70, and 140 g ai/ha. In late July a similar area was sprayed with the same rates as well as a tank mix of DPX-6376 and DPX-5648 at 70 + 70 and 70 + 140 g ai/ha. Turf height, injury ratings, seedhead counts and clipping weights were taken. For one month, all June treatments reduced height, seedheads, and clipping weights. The 70 g and 140 g ha rates reduced seedheads the longest. Some minor, short-lived injury to the common bermudagrass occurred from the 140-g rate. All July treatments reduced seedheads and clipping weights for at least 4 weeks. DPX-6376 at 140 g/ha and the combination treatments gave the best overall reduction, but the combination treatments caused some yellowing of the turf for about 2 weeks. When inhibition effects wore off, growth in some treated plots was significantly faster than in the check plots."
