Abstract

Event is a plant growth regulator that was applied to rough turfgrass at Coles County Airport, Charleston-Mattoon at rates of 0, 8, 10 and 12 ounces per acre. Each of the 12 plots was divided into three sections "mowed", "mowed once" and "unmowed" at application time. The mowed portion was sampled at two week intervals for a six week period and biomass recorded in grams dry weight. Prior to mowing, all the plots were visually observed for broadleaf weeds control, height and seedhead suppression, discolouration and phytotoxicity.

The 12 ounces rate of Event significantly suppressed seedhead production, height, broadleaf weeds control and the biomass production. No discolouration nor phytotoxicity was observed. The results suggest the optimum application rate for maximum growth suppression is 12 ounces per acre.
