Yellow Patch (Cool-Weather Brown Patch) Fungicides

Yellow Patch (Cool-Weather Brown Patch) Fungicides

Yellow patch, also called cool-weather or cool-season brown patch, is caused by Rhizoctonia cerealis during cool, wet conditions. Products in this collection must have a current label-supported claim for the listed target in turf.

Confirm the Target and Label

Use yellow patch as the canonical tag and treat cool-weather brown patch as an alias rather than a duplicate collection. 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.
