Have you ever had a brown patch with a reddish tinge on your lawn and wondered what it is? If it’s not spray paint or your kid’s paintball gun, it’s probably red thread lawn disease. Red thread is not the deadliest lawn disease, but you don’t want to take it lightly. Severe cases of this disease can kill the grass completely.
Red thread lawn disease is common in red fescue grass and perennial ryegrass. Bermuda, bentgrass and Kentucky bluegrass are sometimes affected.
