Abstract/Contents: | "Annual bluegrass (Poa annua) is the dominant species on putting greens in California. Salinity stress from either recycled irrigation water or accumulation of salts in a Mediterranean climate is especially injurious to this species on intensively managed surfaces. The objective of this study was to evaluate 26 products applied alone or in combination for their ability to alleviate stress caused by saline irrigation water (4.4 dSm-1) on a sand-based annual bluegrass 'Two Putt' putting green. Treatments were applied at weekly to monthly intervals prior to introduction of saline irrigation water. In addition to subjective ratings, DIA, NDVI, soil VMC and EC, and complete soil analyses were recorded during the study. During the first half of the study, treatments containing mostly nutrients and biostimulants produced the best turf quality and density in response to salinity and drought stress. Unexpected extremely high temperatures followed by rainfall in higher than normal humidity resulted in outbreak of rapid blight disease caused by Labyrinthula terrestris in plots of most all treatments except for the fungicides. At the end of the study, mefentrifluconazole + pyraclostrobin and penthiopyrad + potassium phosphite + pigment produced the highest turf density and quality. None of the treatments reduced salinity in the upper 10 cm of the rootzone. Results of this and previous research conducted by our program point toward sufficient or even elevated fertility as being most important for alleviating salinity stress as long as disease pressure in minimal. We also continue to substantiate that penthiopyrad, acibenzolar, and potassium phosphite + pigment have activity against rapid blight disease, possibly indicating that different biotype(s) of the pathogen exist in California." |
