If you are asking if it will cause brown spots in your lawn, it will only harm your lawn if you mis-use it and cause burn by over applying or not following label instructions. If you are asking if it will cause brown patch disease in your lawn, no it will not and if your lawn has a tendency of having brown patch you need to start doing a preventative fungicide application before the signs start appearing.
