USGA Summary Points:In order to understand (a) how golf greens become contaminated with STM (local adaptation vs. dispersal), and (b) how diverse the strains (genotypes) of STM are when compared against off-green (native) strains, we initiated a genetic approach consisting of sequencing the Bryum argenteum genome (RNA and DNA). Seventeen genotypes were sequenced over the last year. Manuscript submitted on "The Effects of Carfentrazone Ethyl on the Growth and Survival of Bryum argenteum, the Silvery-Thread Moss". An abstract of this manuscript is given under Results to Date. Experiment on the effectiveness of SDS (sodium dodecyl sulfide, a surfactant in soaps) is completed and the data are under preparation for a second manuscript. SDS was superior to carfentrazone in suppressing STM, with a dosage of 0.5% concentration for one minute reducing the photosynthetic capacity to levels associated with cell death (Fv/Fm <0.2). Shoot regeneration was suppressed to ~10% of controls (near complete shoot suppression), unlike the carfentrazone treatments. The treatment (0.5%) used in the lab is much less than the SDS concentration of Dawn® dishsoap (~20%). Drench applications of Dawn dishsoap and SDS resulted in greater long-term reduction of STM compared to applications of carfentrazone in a research putting green at Hawks Nest Golf Course in Creston, OH. An experiment was initiated in 2022 to help discern whether asexual reproduction from vegetative structures or sexual reproduction from spores is functioning as the primary dispersal mechanism.
