You can apply Pennant Magnum once or twice annually before weeds emerge. The max rate for Pennant Magnum depends on what type of area you are using it in. Per the product label: For commercial sod production, do not apply more than 4.2 pt/A per year to the same area used for sod production. For other turf uses, do not apply more than 2.6 pt/A per year.
