Abstract/Contents: | "Centipedegrass is a slow-growing perennial warm-season turfgrass that possesses stolons and no rhizomes. When grown for turf, centipedegrass performs best under low fertility schemes and exhibits vigorous horizontal spread with little vertical growth. However, when grown commercially with the intention of maximizing seed production, fertility and irrigation frequency increases. These management practices lead to a proliferation of foliar growth, thatch, and stolon stacking that in turn may escalate into winter kill and/or delayed spring transition. The objective of this experiment was to determine if trinexapac-ethyl could be used to decrease foliage biomass without reducing centipedegrass seed yields. Trinexapac-ethyl (Primo MAXX) was applied at 11 or 22 fl. oz/A, at 21 days before mowing stopped (DMBS), 21 and 7 DBMS, or 7 DBMS. One-half of all plots were then treated again with 11 fl. oz/A of trinexapac-ethyl at 30 days before seed harvest (DBH). Trinexapac-ethyl reduced centipedegrass foliar biomass by 10 to 45% for all treatments without the 30 DBH application, and 40 to 60% with the additional application at 30 DBH. Although seedhead number was not reduced at any trinexapac-ethyl treatment timing or application rate, seed yield was decreased between 30 and 60% for most treatments. An exception occurred with trinexapac-ethyl applied sequentially at 7 DBMS (11 or 22 fl. oz/A) and 30 DBH, in that foliage growth was decreased by approximately 45% and seed yield was not statistically reduced." |
