Signature is a patented systemic fungicide that's recognized as the foundation product of every Summer Decline program. Applying multiple Signature tankmixes prior to the onset of turf stress effectively protects turf from stresses associated with Summer Decline, such as high heat and humidity, increased traffic and low mowing heights, and diseases. As a result, turf quality, which is measured in terms of color, vigor, uniformity, playability and disease control, is also improved.
