Snow Mold

After a long winter, the extended snow cover at Sagamore caused some area to develop a disease called snow mold. We have found this disease on many approaches where snow had drifted for long periods of time and in some rough areas. The extent of injury was mild and we are confident the turfgrass will recover completely.

What is Snow Mold?

Snow mold is a fungal disease that appears in the early spring as the snow melts. There are two types of snow mold. Grey snow mold (also known as Typhula blight) and pink snow mold (sometimes referred to as Fusarium patch). Pink snow mold infects the crown of the plant and can cause more severe injury than gray snow mold which only infects the leaf tissue.

What causes snow mold?

Snow mold is caused when there is an extended period of snow cover on ground that is not completely frozen. It can also be brought on by a badly timed fertilizer application which causes a flush of growth too late in the fall. Snow mold can also occur under leaves that have not been cleaned up or amongst long grass that should have been mowed once more before winter set in.
