Conquer Spring Seedings with Fertilizer + Mesotrione

Tackling your spring renovation or seeding project can feel like an uphill battle against weed competition. New seedlings need help to get started, and that means not having to contend with weeds along the way. This doesn't have to be a fight you face alone.

Mesotrione herbicide provides unmatched weed control, suppressing many of the most troublesome weeds, and allowing seedlings to thrive. Pairing Mesotrione with a high-quality starter fertilizer delivers a combination designed to promote seedling germination while keeping problem-causing weeds in check.

21-22-4 Fertilizer with Mesotrione does just that. This unique combination of starter fertilizer and Mesotrione herbicide is ideal for use during turf establishment, renovation, or overseeding to control selected grassy and broadleaf weeds while providing a high-quality starter fertilizer that encourages germination and rapid establishment.

About Mesotrione

No other product has the weed control spectrum of Mesotrione, which suppresses many of the most troublesome pre and post-emergence grassy and broadleaf weeds, allowing new turf seedlings to thrive.

Mesotrione is based on a naturally-occurring compound that inhibits photosynthesis in susceptible plants. It is absorbed by plants through the roots, shoots, and leaves, allowing sunlight to destroy the chlorophyll and bleaching susceptible weeds. This bleaching typically occurs within a week of application, killing weeds and allowing desirable turf to recover after several weeks.

Primary weeds controlled by Mesotrione include:

  • Crabgrass
  • Yellow woodsorrel
  • Chickweed
  • Buckhorn plantain
  • Hairy bittercress
  • Dandelion
  • Clover

Weeds NOT controlled by Mesotrione include:

  • Sedges
  • Poa annua

For a complete list of controlled weeds, consult the product label.
