    Nitrogen Source, Rate, Timing and Fungicides on Dollar Spot Incidence (2006)


    Abstract: Dollar spot (DS) (Sclerotinia homeocarpa) is a major disease problem on golf course greens, tees, and fairways. Low nitrogen (N) fertility and dry soils contribute to an increase in DS incidence, while disease development is favored by warm, humid weather and cool nights that produce heavy dew. Limited data exists regarding N source, and timing, including fertilizer applications in conjunction with low… Read More +

    2005 Grigg Foliar Fertility Study 


    Summary
    Golf Course Superintendents manage creeping bentgrass greens using management strategies that will provide smooth, uniform, fast, healthy greens. This strategy often involves keeping bentgrass “lean” or spoon fed to minimize unwanted top-growth and succulence. Foliar or liquid feeding has become a standard spoon-feeding approach. Research, however on the benefits of liquid/foliar feeding on turf performance, health, disease, and soil nutrient dynamics is limited. Initial research at OSU has shown… Read More +
