Lethal ring area is caused by a fungus which rots the roots and crowns of turfgrasses. Initially, 3- to 4-inch size necrotic, or brown, patches appear in the grass. The areas expand to 512 inches in diameter as the illness establishes. Turf or weeds might fill in the center of older spots, producing a phenomenon described as a "frogeye" pattern.

Dead spots become noticeable during hot, dry weather because the yard is not able to take in sufficient water to remain green.

In addition, light and regular irrigation throughout hot, dry periods may help the afflicted grass endure.

Rusts happen on all turfgrass types but are primarily observed on seasonal ryegrass and Kentucky bluegrass. The primary rust observed on Kentucky bluegrass is stem rust and the main rust observed on seasonal ryegrass is crown rust.

This disease occurs during durations of sluggish turf growth in the late summertime and fall. Rust seldom eliminates the grass, however it can considerably stunt turfgrass growth, provide the lawn an unsightly look, and stain shoes and clothes when its spores rub off. To accelerate recovery, apply a little amount of fertilizer (as much as pound of nitrogen per 1000 sq ft) and gently water.

Leaf area is triggered by 2 primary types of leaf area diseases, Bipolaris leaf spot and Drechslera leaf spot. All turfgrass types are prone, although greatly fertilized, overwatered turf is most vulnerable. Two stages of the disease, each triggered by a various fungus, occur throughout the year. Drechslera leaf area happens during cool, damp weather in the spring and fall.

Bipolaris leaf area happens throughout hot and wet conditions throughout the summer, and red or pink-colored sores can blight and discolor the turfgrass stand. With both leaf spot diseases, extreme infection can result in plant thinning or death. In many cases, nevertheless, the turf is momentarily blemished throughout infection but the turfgrass recuperates once the ecological conditions change and no longer prefer fungal growth.
