Abstract/Contents:Presents a study "to determine the relationship between several environmental, cultural, and physiological factors to the development of bermudagrass decline." Reports that "summer fungicide applications did not control bermudagrass decline. The phototoxic effects of several fungicides, due in part to application when summer temperatures were high, may actually have been counter productive to recovery from bermudagrass decline." Also reports that vertical mowing and increased nitrogen application increased decline on some cultivars. States that "bermudagrass decline symptoms were less severe in Tifdwarf than in several of the newer dwarf bermudagrass cultivars." This three-year study began in 2000.

USGA Summary Points:Summer fungicide applications did not control bermudagrass decline. Fungicide phytotoxicity when summer temperatures were high may have been counter productive to recovery. Decreased mowing height did not increase decline symptoms and in one season were more severe on 0.188 than 0.125 inch mowing height. Vertical mowing increased decline symptoms and light frequent vertical mowing during the summer was devestating to Champion, Floradwarf and Miniverde. Increasing nitrogen increased bermudagrass decline on Champion and Miniverde. An acidifying N source reduced and nearly eliminated symptoms of bermudagrass decline when applied to Floradwarf growing on a green with an alkaline soil pH.
