I am also wondering if applying nutrients in a purely foliar form such as this might help in the control of diseases. We were absolutely riddled with disease this year and the 2 main culprits were ones that I had rarely if ever seen in the past. Pythium and Take All Patch. That and the 39 or so days we had over 100 decimated turf everywhere around here this season.
