| Abstract/Contents: | "New laws and increased social pressure are restricting access to certain pesticides within turfgrass management in the Pacific Northwest. Oregon's school integrated pest management (IPM) law requires that K-12 school districts implement an IPM plan intended to reduce pesticide use. Public schools are also dealing with substantial budget limitations. The goal of Oregon State University School IPM Program is to provide public school employees with education that reduces pesticides use, limits pest populations, and mitigates the costs associated with pest management. To supplement this training, three research projects were initiated fall of 2017 at the OSU Lewis-Brown Horticulture Farm in Corvallis, OR on a mixed stand of cool-season turfgrass. The objectives of these projects were to determine how variations in mowing, fertilization and irrigation practices can affect turfgrass quality, weed populations and maintenance intensity. The factors used in the mowing study included height (5 and 10 cm) and frequency (weekly, every other week and monthly). Preliminary findings show that the 10 cm mowing height resulted in significantly fewer broadleaf weeds than plots maintained at a 5 cm height. Treatments utilized in the fertilization study included 0, 4.88 and 9.76 kg m-2 of nitrogen applied annually. Findings from this trial determined that fertilization reduced weed populations as compared to non-fertilized plots, with the higher nitrogen rate showing the lowest incidence of weeds. However, the fertilized plots required more frequent mowing than the unfertilized plots. Treatments implemented in the irrigation study were a non-irrigated control, 5 cm applied once monthly, 0.6 cm applied 4 times per week and evapotranspiration replacement irrigation applied 4 times per week. The plots that received irrigation four times per week regardless of the rate had the highest turf density and greatest turf quality." |
