Abstract/Contents: | "Frequency and severity of anthracnose epiphytotics, caused by Colletotrichum cereale Manns Manns sensu lato Crouch, Clarke, and Hillman, on annual bluegrass (ABG) [Poa annua L. f. reptans (Hauskins) T. Koyama] putting greens have increased over the past decade. This 3-yr field study evaluated the impact of N fertilization (4.9 kg ha-1 every 7 or 28 d), mefluidide (ME; 0 and 0.106 kg a.i. ha-1 yr-1) {N-[2,4-dimethyl-5-[[(trifluoromethyl)sulfonyl]amino]phenyl] trinexapac-ethyl (TE; 0 and 0.050 kg a.i. ha-1 every 14 d) [4-(cyclopropyl-α-hydroxy-methylene)-3,5-dioxocyclohex acid ethylester], verticutting (VC; 0- and 3-mm depth every 14 d), and interactions of these factors on anthracnose of ABG mowed at 3.2 mm. Nitrogen fertilization frequency had the greatest influence on disease throughout the study; N applied at 4.9 kg ha-1 every 7 d reduced damage 5 to 24% compared to a 28-d interval. The plant growth regulators, ME and TE, frequently interacted during the last 2 yr of the study; sequential application of ME and TE reduced disease 6 to 14% compared to plots that only received one of these plant growth regulators. At advanced stages of disease, the combination of 7-d N fertilization and ME and TE application had the greatest disease reduction. Verticutting had little effect on anthracnose severity." |
