Gray leaf spot will target tall fescue and rye grass - though it has affected other cool seasoned grass types as well. The beginning stages of Gray leaf spot are small gray spots. As they expand, they form dark borders and mimic the look of being scorched. The disease will cause the leaf of the grass to become discolored, usually graying from the tip down.
Fungicides are not usually warranted, though if you need a technician to come out and review the condition of your lawn, feel free to contact us at 419-536-4344.
