Signature™ XTRA Stressgard® is a true systemic fungicide that enhances plant health and turf quality, while minimizing stress from both abiotic and biotic sources. Signature XTRA Stressgard uses a new, improved formulation of fosetyl-Al. Fosetyl-Al, the same active used in Chipco® Signature, has provided over 20 years of consistently high turf-quality ratings, along with no documented reports of resistance development in the field. The new formulation protects against summer decline and Pythium blight, plus adds stronger control of root-infecting Pythium species when watered in. It can be applied alone or in a tank-mix.
