USE OF TRINEXAPAC-ETHYL TO REDUCE MOWING REQUIREMENTS OF WARM-SEASON GRASSES IN SUBTROPICAL AUSTRALIA
Trinexapac-ethyl is a plant growth regulator used to reduce turfgrass growth and,hence,mowing operations.A one-year study was conducted near Brisbane in subtropical southern Queensland (Australia) to determine the effect on mowing frequency of trinexapac-ethyl applied monthly (at rates of 60- 240 mg/ha of active ingredient) during the active growing period across a range of 19 varieties of four medium- to coarse-textured warm-season turfgrass species (Cynodon dactylon (L.) Pers.,Cynodon dactylon x C.transvaalensis Burtt-Davy,Digitaria didactyla Willd.,Pennisetum clandestinum Hochst.ex Chiov.).For the full year and across all 4 species and 19 varieties,15,17,24 and 29% fewer mowings were required at monthly trinexapac-ethyl rates of 60,96,180 and 240 mg/ha,respectively.Some phytotoxic damage,including stunting of stem and leaf growth and discoloration,was observed at the two higher rates of trinexapac-ethyl.
