    I get a call from one of our high end clients. She says they are having a few areas in their lawn turning brown. For the record we used 24-5-11 at 1/2 rate. That equals 1/2 lb of 50% slow release in March and she is ready for her second application of 11-0-11 Novex Natural. I show up and sure enough it looks like brown patch. We have had very wet conditions. Last week the humitidy was high and it was very muggy. The last few days have been ideal, with high temps in the mid 70's with very low humidity. Any suggestions.

    Brown Patch is a root borne fungus. Instead of foliar pictures, what do the roots look like?

    I think it is dollar spot, but I just don't understand. Received normal amounts of fert. 1/2 lb in spring and just hit it with 1lb of N. Here are more pics.

    Pics sure look like Dollar spot and even with wet conditions the disease will progress and at times track with mowings. Keep fertility rate up and be careful of leaf spot if your temps have been cool like here.

    had sample under microscope and you are both correct. I have both leaf spot and dollar spot. Will be treating in AM with fungicide.
