Maximum Yearly Limits
DO NOT apply more than 16 oz. (or 0.50 lb. mesotrione per acre per year) per acre per year or per crop whichever is shorter.
If applied pre-emergence, it is absorbed when emerging from the soil. Pre-emergence activity and control is reduced under dry conditions. Activate Meso 4 SC Select with 0.15 inches of irrigation if rain hasn’t fallen within 10 days of application for pre-emergence.
Before Seeding Instructions
Apply 5-8 fl. oz. Meso 4 SC Select per acre in at least 30 gallons of water per acre before seeding or after seeding of tolerance turfgrass species listed below, except fine fescue, as application to fine fescue can reduce grass density. Meso 4 SC Select can be effectively used on grass seed blends that contain <20% by weight hard/fine fescue. For optimal control, apply at grass seeding or as close to seeding as possible.
After Seeding Instructions
DO NOT spray on newly germinated turfgrass. Delay treatment until grass has been mowed 2-4 times and/or 4 weeks after emergence (whichever is longer).
Add a nonionic surfactant when making post- emergence applications.
