| Abstract/Contents: | "Dollar spot (Clarireedia homoeocarpa ??) is a common disease of turfgrass worldwide, which typically requires multiple fungicide applications for control. Naturally suppressive organic amendments are one alternative management tool being considered by those seeking to reduce dependence on chemical inputs. There is a need to evaluate new organic products for dollar spot suppression and for their impact on residual fungicide efficacy. A 2-yr trial was initiated in late 2016 on creeping bentgrass (Agrostis stolonifera L.) maintained as a golf course fairway to evaluate fertility and fungicide source for impact on dollar spot development on a newly established creeping bentgrass cv. 007 fairway. Main-plot treatments were applied as a municipal waste compost and a biochar applied at establishment and as a topdressing applied bi-annually, a vermicompost + fertility treatment, a standard fertility treatment, and none. Nitrogen fertility levels for all treatments were standardized at approximately 3.75 lbs. of nitrogen per 1,000 sq. ft. annually. Sub-plot fungicide treatments were applied as a 14 d contact, contact threshold, 14 d penetrant, penetrant threshold, and none). In the first year of the study, we observed no difference between fertility source effects on seasonal dollar spot suppression, as all fertility sources were significantly better at controlling dollar spot than our non-fertilized check. When considering threshold-based fungicide applications, the vermicompost + conventional fertility treatment provided the longest duration of control for both contact and penetrant fungicides. In the second year of the trial..." |
