Boeremia exigua Fungicide

Description of Ascochyta Leaf Blight (Boeremia exigua):
Ascochyta leaf blight is a common fungus problem for kentucky bluegrass lawns; especially in Colorado. The process is as such: leaves start drying down the leaf from the tips, which causes large and uniform areas of turf to become the color of straw. The symptoms are most common when a cool, rainy period follows a hot, drought period. The turf's crown and root are typically not killed, as blights usually just affect the leaves.
According to the manufacturer approved labels: The following 2 fungicides, applied at the listed application rates, will control Ascochyta Leaf Blight.
