Cool Weather Diseases

The cool wet weather leads to certain diseases showing up on the course. Waitea Patch, Leaf Spot, Microdochium Patch, just to name a few.
The picture below is of Yellow Patch. Being Enviromental Stewards we do not treat for this disease because although ugly, this disease does not affect ball roll, does not threaten the long term health of the Turf, and after some consecutive warm temperatures starts to dissipate.
