| Abstract/Contents: | "Setaria pumila (Poir.) Roem. & Schult. (1817) and Setaria parviflora (Poir.) Kerguelen, respectively known as yellow and knotroot foxtail, are two common weeds species infesting turf in the southeastern region of the United States. Yellow and knotroot foxtail share morphological similarities and are frequently misidentified by weed managers, thus leading to confusion in the herbicide selection. Previous studies showed that yellow foxtail is controlled by herbicides in the acetyl-CoA carboxylase and the acetolactate synthase group; however, little research has been done to understand knotroot foxtail control in turf. The research was conducted on greenhouse and naturalized field populations to evaluate yellow and knotroot foxtail response to select herbicides. Three different studies were conducted (1) initial greenhouse herbicide evaluation, (2) rate response evaluation to sethoxydim and pinoxaden, and (3) a field study to evaluate bermudagrass injury from possible herbicide treatments. For the first experiment, herbicides included: Pinoxaden (2rates), Sethoxydim(2rates)), Thiencarbazone+Dicamba+Iodosulfuron, Nicosulfuron +Rimsulfuron, Metribuzin, Sulfentrazone, Sulfentrazone+Imazethapyr , Imazaquin applied respectively at 0.034, 0.070, 0.31, 0.52 kg ha-1, 0.23 , 0.56, 0.039 0.33, 0.504 and 0.55 kg ha-1. This study was repeated in field trials on bermudagrass in the summer of 2021 and 2022. For the rate response studies, Pinoxaden rates were: 0.002, 0.004, 0.008, 0.017, 0.034, 0.068, 0.136, 0.272, 0.544 kg ha-1 and Sethoxydim rates were :0.019, 0.039, 0.078, 0.15, 0.31, 0.62, 1.25, 2.50, 5 kg ha-1. All the trials were arranged in a randomized complete block design with four replications and were repeated two times. Treatments were compared with a nontreated control. Herbicide injury was visibly evaluated relative to the control on a 0% (no phytotoxic effect) to 100% (total plant death) scale at 7, 14, and 28 or 42 days after application (DAA)." |
