Rhizoctonia blight

Brown Patch appears, usually in fescue, as brown blotches scattered through the turf. It can also develop in warm season turf as it breaks dormanct.  It is associated with a variety of conditions which may include any or all conditions such as: high nitrogen levels, high humidity and temperatures and improper watering techniques.

Dollar spot appears as small silver dollar size blotches, usually in warm season turf. The key word here is blotches. Very seldom do we see the distinct spots caused by dollar spot fungus that are common on golf greens. The presence of dollar spot can indicate compaction problems, too much thatch, or is simply an indicator that available nutrient levels are dropping and should be replenished. This year this disease will be very active due to the weather being conducive to disease development.
