Curative Treatment of Spring Dead Spot of Bermudagrass
Spring Dead Spot (SDS) is a common disease of bermudagrass in well-maintained lawns in Oklahoma. It occurs mainly in spring and early summer as bermudagrass comes out of dormancy. Lawns that are not well-fertilized, irrigated, or treated with herbicides are less likely to develop severe SDS. New symptoms of SDS do not appear in actively growing bermudagrass stands in mid-to-late summer or fall in Oklahoma.

This fungicide treatment plan is formulated and timed to address the fungal activity that leads to Spring Dead Spot of Bermudagrass. This application plan provides preventative and curative control of many turfgrass and ornamental diseases by inhibiting the incorporation of ergosterol into the growing fungal cell membranes. Without ergosterol, fungal cellular growth is stopped. By disrupting fungal growth at the earliest possible stage, the impact and effects of the disease are minimized.
