This turf disease is commonly mistaken for Take All Root Rot. Brown patch disease can also be referred to as large patch, and is a fungal disease that turns your blades of grass yellow, creating brown patches. While they show similar symptoms, root rot ruins your roots, while brown patch directly attacks the blades of grass themselves. Brown patch can and does show up in warm-season grasses like Zoysia, St Augustine, and Bermuda. However, it most devastatingly affects cool-season turfgrasses like Ryegrass and Tall Fescue. It can occur at any time throughout the year, varying based upon the type of turfgrass. Brown patch does best in moisture filled lawns, so dialing back feeding and watering may help.
