| Abstract/Contents: | "A growing list of communities in the United States have banned synthetic pesticides in recent years on athletic fields. Previous research has demonstrated that common turf weeds don't handle traffic as well as turfgrass monostands. Corn gluten meal (CGM) has been shown to be an effective natural preemergence herbicide. However, data is lacking for the performance of CGM under athletic traffic. A two-year field trail was conducted at Iowa State University comparing the performance and safety of spring and fall CGM applications to a conventional weed control program (synthetic preemergence herbicide in the spring and broadleaf weed control in the fall) and to an untreated weed control treatment. The study was subjected to fall simulated athletic field traffic mimicking the Iowa High School Football Season. Performance of the playing surface was quantified by weekly percent green cover, surface hardness ratings, and surface stability. Visual stand ratings were also taken to note how many weeds were present. No weeds were present in either the conventional or CGM treated plots at the beginning of the traffic season. Percent green cover was higher on the CGM treatments compared to the untreated plots on 4 of 5 rating dates, and the conventional treatments had higher green cover on 3 of 5 rating dates compared to the control treatment in 2017. Surface hardness only varied between treatments on the 29 Sept. 2017 rating date. CGM treatments (56 GMAX) resulted in lower surface hardness than the conventional (61 GMAX) and the untreated (61 GMAX). No differences existed on any rating date for surface stability. First-year results indicate that CGM has the potential to be a tool for weed control and for improving athletic field safety when conventional weed control programs are banned." |
