Tenacity Herbicide

Tenacity® herbicide can be used for pre- and post-emergence control of more than 46 broadleaf weed and grass species. Its active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus)
Key Features
• Weeds controlled include crabgrass, ground ivy, yellow foxtail, yellow nutsedge and nimblewill.
• Provides post-emergent control of tough-to-control weeds
• Controls weeds at seeding reducing weed competition
Key Benefits
• Prevents and controls crabgrass pre or post up to four tillers (leaflets)
• Eliminates weeds at seeding so new grass can flourish.

Pre-emergence Applications
• When applied as a pre-emergent, weeds absorb Tenacity during emergence from the soil.
• Dry conditions following application may reduce the pre-emergence activity. If rainfall (0.15 inches) has not occurred within 10 days after a pre-emergence application, activate with 0.15 inches of irrigation.
Post Emergence Applications
• When used as a post-emergent, susceptible weeds absorb Tenacity through foliar contact and soil absorption.
• Foliage of treated weeds cease growth after application, then turn white (loss of chlorophyll) and death may take up to three weeks. A repeat application is required after two to three weeks for improved post-emergence weed control.
• A non-ionic surfactant, such as Bonide Turbo Sticker, should be added in post-emergence applications.
