Abstract

Vegetative growth of ‘Tifway’ African bermudagrass (Cynodon transvaalensis Burtt-Davy # CYNTR) x bermudagrass [C. dactylon (L.) Pers. # CYNDA] treated with flurprimidol {α-(1-methylethyl)-α-[4-trifluoromethoxy)phenyl]-5-pyrimidinemethanol} at 0.2 kg/ha and repeated at 3-week intervals for a total rate of 0.8 kg/ha was suppressed for 6 weeks compared to growth of nontreated grass. A single application of flurprimidol at 0.8 kg/ha in late May suppressed growth for 4 weeks. When the single 0.8 kg/ha application was delayed until mid-July, bermudagrass growth was suppressed for only 2 weeks. Applications of nitrogen (N) at 25 and 50 kg/ha did not influence flurprimidol's suppression of bermudagrass growth. Turf quality in some instances was lower when treated with 50 kg N/ha or the turfgrass required a longer recovery period than when treated with 25 kg N/ha following flurprimidol treatment. Although single or multiple applications of flurprimidol, each totaling 0.8 kg/ha, injured bermudagrass in some instances, the injury was not severe and the turfgrass fully recovered.
