Tenacity® herbicide is a systemic herbicide for pre- and post-emergent control of grass and broadleaf weeds in several cool- and warm-season turf species. The active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus). Tenacity works by inhibiting the synthesis of carotenoids in susceptible plant species. Without carotenoids, light energy and by-products of photosynthesis destroy chlorophyll and cell membranes, resulting in bleaching of leaves and plant death.
Tenacity, available in a convenient squeeze-and-pour bottle, provides control of major turf weeds including:
Crabgrass 
Goosegrass
Lovegrass
Chickweed
Dandelion
Oxalis
Speedwell

Product use rates range from 5-8 oz./A. A repeat application in two to three weeks may be necessary for weed control. Tenacity also controls bentgrass and nimblewill contaminations in Kentucky bluegrass and perennial ryegrass turf, and it is compatible with a seeding program into treated areas to enhance conversion.
Tenacity offers several unique features including, including the ability to:
Provide clean up for summer annuals and perennial weeds such as crabgrass, clover, dandelion and oxalis in late spring and early summer
Tank mix with a post-emergent herbicide, such as triclopyr (TE) or dicamba, to enhance post-emergent control of crabgrass and dicot weeds (see chart below)

Tenacity can also be used at seeding to reduce weed competition and establish a lawn faster. When applied just prior to or at seeding of tall fescue, Kentucky bluegrass and perennial ryegrass, Tenacity will help control crabgrass, purslane and carpetweed (among other weeds) that seem to germinate at turf renovation. Tenacity can also be added to the hydro-seeding tank for seeding large areas.
