Control of Spring Dead Spot of Bermudagrass with Fungicides in North Carolina. L. T. Lucas, Professor, Department of Plant Pathology, North Carolina State University, Raleigh 27650. Plant Dis. 64:868-870. Copyright 1980 American Phytopathological Society. DOI: 10.1094/PD-64-868.

Spring dead spot (SDS) of bermudagrass was controlled with five monthly applications of benomyl, PCNB, or a combination of fungicides during July–November in 1973 and 1974. Applications of chloroneb, nabam, maneb, or carboxin did not control the disease. The severity of SDS increased in plots without fungicides that received extra nitrogen in August and September. SDS was controlled in the spring of 1976 and 1977 with three monthly applications of benomyl at 145 g a.i./93 m2 in the fall (October, November, and December) and with single applications in October or November of 1975.
