Bermuda Fungus, Dead Spots & Discoloration
Prevention: apply PRO DG Fungicide when temps reach 80s in spring. Most common fungi: Dollar Spot (small circular patches) and Brown Patch (larger irregular patches). Treatment: apply P-DG fungicide at bag rate up to 3 times, then SWITCH to BioAdvanced spray (rotating chemicals prevents resistance). Yellow blades (chlorosis): caused by over-watering, high phosphorus, or pH imbalance. Quick fix: Super Juice + extra liquid iron. Red/purple blades: usually stress/cold damage or lack of phosphorus.
