| Abstract/Contents: | "Asiatic dayflower (Commelina communis) is an annual monocot weed commonly found in soybean fields throughout the Midwest. Within the fine fescue (Festuca spp.) roughs of Merion Golf Club - East Course (Ardmore, PA), however, this weed has become an invasive and problematic nuisance. The result is a reduction in visual quality of the naturalized look of the fine fescue roughs, a reduction in desired turfgrass stand density, and consequently negative impacts on playability of golf in the roughs. Therefore, the purpose of this investigation was to evaluate commercially available herbicide products for control of Asiatic dayflower. Mature and aggressive Asiatic dayflower plants were collected from several areas at Merion Golf Club on June 28, 2008 and immediately transplanted to plastic pots (6 in. diam. x 6 in. depth) filled with potting soil and transported to Pennsylvania State Berks Campus (Reading, PA). On August 7, 2008, herbicide treatments (Table 1) were applied only once from a CO2 - pressurized backpack sprayer calibrated to deliver one gal water-carrier per 1000 sq ft through an XR8004E flat-fan nozzle at 40 psi. Treatments consisted of one target plant (4-6 tillers, 12-16 in. ht.) per pot arranged as a randomized complete block design with three replications. Target plants were visually evaluated for injury/phytotoxicity on a 0 to 100% scale, where 0 = no injury and 100 = complete injury or death. Data were subjected to analysis of variance and treatment means compared with Fisher's least significance difference test at P < 0.05. Turflon® Ester provided the best control (i.e ., leaf necrosis, wilting, stem collapse), although noticeable suppression was observed from products containing 2,4- D and/or dicamba at 14 to 28 DAT. Future research should examine herbicide products in sequential applications and timings for both post- and pre-emergence control of this weed in turfgrass." |
