| 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). Two genotypes were sequenced over the last year. An experimental analysis of the effects of carfentrazone and SDS (sodium dodecyl sulfide) applications to STM continued, and two manuscripts are in preparation. Effective suppression of STM by carfentrazone was observed at a high dosage (12.5 × recommended dosage), and only when followed by a 10-hour exposure to a full sunlight equivalent (2000 μmol m-2 sec-1 PAR, photosynthetic active radiation). 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 ~90% of controls, 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. At Scioto Country Club in Upper Arlington, OH, overall STM control was reduced (<20% of control) for all treatments. |
