| Abstract/Contents: | Discusses the occurrence of large patch in seashore paspalum. Briefly discusses the introduction of seashore paspalum to the United States. States that "seashore paspalum exhibits little disease incidence in its naturalized habitat, however, under the high maintenance programs on modern golf courses, several diseases have been found to cause severe damage under typical management and environmental regimes." Discusses documented seashore paspalum diseases, including large patch, dollar spot, and necrotic superficial fairy ring. Presents a study conducted to evaluate "the description of large patch symptoms, identification of the causal agent, cultivar susceptibility to the disease, and curative effects of fungicides on large patch." States that "samples were collected from solid, large brown patches up to several meters in diameter from a putting green at Old Collier Golf Club, Naples, [Florida] in February, 2005." Reports that "the strains from seashore paspalum fused with a tester from zoysia and clearly placed the fungus into R. solani AG 2-2 LP. Further inoculations onto seashore paspalum reproduced the symptoms of large patch, and the fungus was re-isolated and shown to be identical to the inoculated fungus. This proved pathogenicity and showed the causal agent to be R. solani AG 2-2 LP and the disease on seashore paspalum to be large patch." Evaluates "cultivars of seashore paspalum and fungicides on large patch." Discusses occurrences of large patch at the Pee Dee Research and Education Center in July 2005, September-October 2005 and at the May River Golf Club in 2005. Reports that "large patch symptoms in natural epidemics on seashore paspalum in South Carolina were generally similar to the disease as it is known in other warm-season turfgrasses." Discusses fungicide control of large patch, stating that "there were significant differences in the reactions of cultivars of seashore paspalum to large patch and there were significant effects of fungicides on the disease...None of the fungicides tested provided complete control." Concludes that "all the cultivars under the study were very susceptible to large patch disease...The fungicides sprayed after severe epidemics did not provide adequate control of the disease. The use of preventive applications of fungicides is highly recommended to control large patch on seashore paspalum." |
