Every season of the year is fraught with its own list of diseases that can impact golf course management. Fall in particular can be problematic, as this is the time of year when many other management practices can take the front stage. Warm days and cool nights that produce heavy dews are conducive for the development of diseases like dollar spot and Drechslera leaf spot. However, taking steps to prevent fall diseases like these can help turf emerge healthier in the spring.

The key to fall disease control is to plan preventive fungicide applications prior to a disease outbreak. Secure® and Velista® fungicides are great options to help control key diseases this fall. Secure provides the protection of a multi-site contact fungicide, while Velista delivers systemic control.

Dollar spot and leaf spot can be controlled with properly scheduled fungicide applications starting after Labor Day. Secure applied at 0.5 fl. oz. is labeled for control of dollar spot for 14 days, while Velista applied at 0.5 oz. is labeled for 14 to 21 days control of dollar spot.

Rotating Velista and Secure will provide contact and penetrant protection from these diseases. In addition, Velista provides enhanced protection from diseases like anthracnose, brown ring patch and cool-season brown patch.
