Fusarium typically starts to develop once temperatures cool off in the fall, initially appearing as small, orange to red-brown circular patches.

If left untreated, fusarium can spread quickly and leave several circular patches of pale, brown grass with a dark brown outer ring.

In the spring, cold and wet weather can trigger the development of new patches around the edges of areas affected in the previous fall, and may continue into the summer if cold, wet conditions persist.

Timely fungicide application in the fall and spring when fusarium is most active and maintaining optimal moisture levels using proper drainage and aeration techniques is key when trying to prevent and control fusarium.
