However, any above-ground part of the plant can display the mildew. The mildew will thrive in high humidity and moderate temperature environments. This disease appears most in the spring and fall. Cool, cloudy conditions, and shade are feeding grounds for this disease.

As the most common turf grass disease, it is often found in lawns using low nitrogen fertilizer.  The disease first appears in small patches with white and cream colored blades. It is managed by pruning trees and shrubs. This is to promote canopy drying and to increase nitrogen fertility. For further information about red thread click here.


rustThis disease causes thinning in the turf but will not kill the host plant. First appearing as yellowish spots, these spots develop into orange or red blister-like areas filled with orange or yellow spores. The nitrogen fertility is the most effective management technique.

A Watchful Eye

Applying too much or not enough water can result in unhealthy, slow-growing grass that is vulnerable to pathogens. Water deeper, not more. Deeply watered lawn forces grass roots to reach further in the soil. This develops deeper and stronger roots. This provides grass with greater drought and disease resistance than a shallowly watered lawn.

Keep an attentive eye on your client’s turf. Turf should be inspected once a week to immediately identify problems and act quickly to determine the cause before it’s too late. Diseases tend to start off as small patches or spots of dying grasses that spread over time.

During the rainy seasons, drainage can also contribute to turf diseases. Drainage is important in healthy greens. Poor draining soils, improper grade and irrigation are usually the cause of drainage problems. Talk to your local Wolf Creek Company Representative with any questions.
