| Abstract/Contents: | Presents research "focused on developing fungicide programs for spring dead spot that are specific, effective and reliable...[and] to provide superintendents with more options to manage this destructive disease in high-value areas." Explains that "although the aboveground symptoms of spring dead spot are most striking, the disease actually develops belowground in the roots, rhizomes and stolons. Three fungal species have been shown to cause spring dead spot: Ophiosphaerella herpotricha, O. korrae, and O. narmari...For effective control of summer patch and take-all patch, the timing and method of fungicide application is critical. Applications must be initiated early, when the pathogens are just beginning to grow and infect roots." Reports that "in 2003, Banner Maxx, Heritage and Rubigan significantly reduced spring dead spot incidence on field [number] 4, but only Banner Maxx and Rubigan controlled the disease on field [number] 5...Overall, Rubigan provided the best control, reducing spring dead spot from 11% to 4% on field [number] 4 and from 8% to 4% on field [number] 5." Concludes that "based on [researcher] results and observations, preventive control of spring dead spot with fungicides is possible. However, complete disease control apparently cannot be obtained within two years following initiation of a fungicide program. Long-term research is needed to determine whether the level of spring dead spot control will improve after several successive years of preventive treatments. It should be emphasized that this study was conducted on sites that were infested with O. korrae and that these strategies may not apply to managing spring dead spot caused by other Ophiosphaerella species." |
