Protect your bermudagrass greens now to maximize spring quality

By Lane Tredway, Ph.D., technical services manager, Syngenta

Fall is upon us, and as days become shorter and temperatures become cooler, bermudagrass greens begin to suffer from energy deprivation. When combined with stresses like close mowing, traffic and wet weather, bermudagrass becomes susceptible to a range of diseases, including: 
​​​​​​​
Without fungicide protection, bermudagrass gradually declines through the fall and enters dormancy in a weakened state, which can lead to slow spring green up — or worse, significant turf loss. Syngenta agronomic programs for bermudagrass greens have been refined through years of research and can help protect grass through the fall and provide a faster, more uniform spring green up.

Spring Dead Spot and Take-all Root Rot Assurance Program 

This new Assurance Program from Syngenta recommends the following applications on a 28-day interval beginning in late summer when soil temperatures are consistently below 80°F. Sign up for soil temperature alerts to be notified when conditions are right in your area.   
   
These applications should be applied in two gallons of water per 1000 ft.2 and watered-in immediately with at least 0.15 in. of irrigation.  

If these applications fail to provide acceptable control, Syngenta will provide product for curative applications as needed.

Foliar Disease Control 

For prevention of leaf spot, Pythium blight, and other foliar diseases, the following rotational program is recommended: 
       alternated with
These products should be applied in two gallons of water per 1000 ft.2 and allowed to dry before rainfall or irrigation. A 28-day interval between applications is recommended when soil temperatures are consistently below 80°F (typically August-September and April-May). Increase frequency to a 14-day interval when soil temperatures are between 50 and 60°F (typically December, February and March).
