| Abstract/Contents: | "Mustard Seed Meal (MSM) is a byproduct following oil extraction from seeds. This material contains secondary metabolites termed glucosinolates, which can be converted into biocidal isothiocyanates. These volatile compounds exhibit activity on a wide range of turfgrass pests, including weeds. However, even marginal rates of MSM may detrimentally impact turf quality. Research was established to explore various methods of application which could reduce the potential injury of MSM to fine turf. Field experiments were established on 'A4' creeping bentgrass (Agrostis stolonifera L.) maintained as a typical golf course putting green. Plots were arranged in a randomized complete block design with 3 replications and the experiment repeated. Experiment 1 consisted of MSM mixed with sand at single rates of 1000, 2000, and 3000 kg/ha and applied by one of three methods: top-dressing, verticutting followed by topdressing, or aeration followed by topdressing. Experiment 2 consisted of all MSM rates used in experiment 1, but applications only included topdressing or soil aeration followed by topdressing. In addition, the MSM/sand mix in experiment 1 was allowed to remain as a 1.5 mm layer on the turf surface for the soil aeration followed by topdressing application method; in experiment 2 the MSM/sand was lightly brushed to fill the holes following aeration. Results from experiment 1 found that MSM at 2000 kg/ha or above caused visible injury (discoloration) to creeping bentgrass turf within 1week after treatment (WAT). At 1000 kg/ha, turf growth in the MSM topdressed following aeration plots was not significantly affected. Turf quality remained at 6 or above (acceptable level) throughout the experiment. In comparison, MSM at 1000 kg/ha topdressed directly over turf resulted in unacceptable turf quality (< 6) until 6 WAT. In experiment 2, MSM topdressed at 3000 kg/ha significantly reduced turf quality indicated by normalized difference vegetation index (NDVI) at 2 WAT. The same MSM rate, however, did not reduce turf quality when applied after aeration compared to the untreated control. Our results indicate that turf quality is least impacted when MSM/sand is applied to an aerated soil and moved away from contact with grass leaves." |
