| Abstract/Contents: | "Herbicides alone and in combinations were evaluated for control of crabgrass and goosegrass in bermudagrass turf [Cynodon dactylon (L.) Pres.]. Studies were conducted on Loving-Urbo land comples and Marietta fine sandy loam soils in randomized complete blocks of 1.5 by 4.6 m plots replicated four times. Granular (G) herbicides were applied by mixing the appropriate amount with approximately 1 L of sand before uniformly distributing this mixture across the plot. Sprayable herbicides were applied with a carbon dioxide-powered backpack sprayer in a volume of 234 L/ha, except pedimethalin (10% formulation), which was applied in a volume of 1,638 L/ha. Weed control was evaluated using a 0 to 100% scale. Good control of crabgrass was achieved in all studies for 3 to 4 months following mid-March application with benefin + trifluralin [1.7 + 1.7 and 2.2 + 2.2 kg/ha (G)], pendimethalin [3.0 to 3.7 kg/ha and napropamide (4.5 and 6.7 kg/ha)]. No differences were observed between 60% water dispersable, 50% wettable powder and 10% sprayable fertilizer formulations of pendimethalin. Additional applications of 0.5x rates of oxadiazon, benefin + oryzalin, pendimethalin, oryzalin, oxadiazon + benefin and bensulide + oxadiazon generally increased control of both crabgrass and goosegrass. The 0.5x application at 60 days following the initial application was usually better than equivalent applications delayed until 90 days after the initial application, especially on goosegrass. Pendimethalin, DCPA, napropamide, oxadiazon and benefin + oryzalin in combination with MSMA also provided good control of crabgrass when applied in mid-June. Equal control of goosegrass was obtained with oxadiazon, oryzalin, napropamide and pendimethalin in turfs maintained as golf fairways. CGA-131036 (ciba-Geigy), imazaquin, sulfometuron, chlorsulfuron and EL-107 (Elanco) gave poor control of crabgrass." |
