   Has anyone found a correlation between water quality (potable, effluent, re-use, etc.) or water pH and summer patch (or any other fungal disease)?  Three of our courses use potable water and have consistent problems with summer patch.  The other four courses within our system have effluent or lake water and no problems with summer patch.  We have recently undergone an increase in potable pH to low 8's.  Not sure if that would have an effect.  Any actual experience or theories?

   I would say that it is quite possible. Summer Patch and Take-all are worse at high pH levels. I had a friend once who used a lot of organics. Developed a summer patch problem and discovered that one of the organic products (a brewery waste as I recall) had a pH in the 8's.

   If old man Larry were on the forum he could give you great insight into summer patch and pH. He persuaded me to move to melted ammonium sulfate and it's, well, Larry was right. Lower that pH.
