Gray Leaf Spot Fungicides

Gray Leaf Spot Fungicides

Gray leaf spot can develop rapidly on susceptible ryegrass, tall fescue, and St. Augustinegrass during warm, humid weather. Products in this collection must have a current label-supported claim for the listed target in turf.

Confirm the Target and Label

Confirm the turf species and use a label that specifically lists gray leaf spot. Verify the turf species, use site, rate, timing, application interval, placement, and whether the label states control or suppression.

Build the Treatment Program

Compare FRAC groups, activity, formulation, and watering directions. Rotate or combine effective FRAC groups as directed and integrate cultural practices that reduce disease pressure. Always follow the complete product label.
