How To

Designed for newly seeded turf, including interseeding and overseeding, SquareOne is a patent-pending dispersible granule formulation that features a dual action, optimized combination of active ingredients that works primarily through foliar contact and uptake, but also continues to hold back weed competition until the new turf is established. The product mixes easily in water for use in sprayers and/or tank mixed with starter fertilizers. A non-ionic surfactant is recommended, but not required. It is labeled for crabgrass and many small broadleaf weeds, and can be used in both spring and fall turf renovation projects on lawns, athletic fields, sod farms, and golf courses. SquareOne will be available from FMC authorized distributors in the near future. The product will be sold in a convenient, 1 acre package with measuring device that assists with proper measurement for small or large application turf renovation projects. * Not labeled for use on St. Augustinegrass or Creeping Bentgrass. Always read and follow label directions.

Product Q & A

Solutions ()

SquareOne Herbicide

Healthy turf starts with a successful seeding. Unlike other products that are too harsh on newly seeded turf or require multiple applications, SquareOne herbicide can be applied up to one day before seeding or as early as seven days after emergence on most cool and warm season grasses*. This means weed populations are reduced from the start, allowing for maximum turf density with fewer herbicide applications or the need to reseed the following spring.
