• Not for use on turf being grown for sale or other commercial use as sod, or for commercial seed

production, or for research purposes.

This product, containing Dimension® herbicide, can be applied up to 4 weeks later than other crabgrass preventers and provides up to 4 months of crabgrass control.

This product provides preemergence control of crabgrass and control or suppression of other listed weeds when applied prior to their germination. In addition, this product provides postemergence control of seedling crabgrass after germination and emergence. Postemergence control is limited to crabgrass only, but is effective up to 4 weeks after crabgrass has germinated. This generally corresponds to the time when crabgrass seedlings

rst become visible in the established turfgrass. Do not apply this product later than 4 weeks after crabgrass

germination. Apply this product only to turfgrass species listed on this label. The following turfgrass species are tolerant to this

product when applied as directed:

Cool-Season Grasses

Bentgrass, creeping Fescue, tall Bluegrass, Kentucky Ryegrass, perennial

Fescue, ne

Use Precautions for Turf

This product should be applied only to lawns and ornamental turfgrasses that are well established. For newly established lawns, initial application of this product should be made only after turfgrasses have developed a vigorous root system, uniform stand, and received at least two mowings following seeding, sodding, or sprigging. Exception: In newly established lawns of Kentucky bluegrass, perennial ryegrass and/or tall fescue, this product

may be applied two weeks after the rst sign of germination.

• Use of this product on lawns and ornamental turfgrasses that are not well established, or weakened by stress

due to mechanical operations, pests, excessive temperatures, or lack of moisture may result in turfgrass injury.

• For best results, cultural practices that disturb the soil, such as core-, spike-, or hydro-aerication, and

verticutting, should be done before application of this product. Do not apply this product until turfgrass has recovered from the mechanical injury caused by these cultural practices.

• Reseeding, Overseeding, or Sprigging: Reseeding, overseeding, or sprigging of areas treated with this product within 10 weeks after a single application of this product or within 16 weeks after a split application program totaling 4.3 lb/1000 sq ft (0.5 lb active ingredient per acre) or more may inhibit the establishment of

desirable turfgrasses. When reseeding or overseeding follow proper cultural practices for seedbed preparation,

seeding, irrigation and fertilization.

Other Use Precautions

• Do not use clippings from treated turf for mulching around vegetables or fruit trees.

• Do not allow people or pets to enter treated area until dust has settled.

SPRING APPLICATION

Control of Crabgrass: This product provides preemergence control of crabgrass and control or suppression

of other listed weeds when applied prior to their germination. In addition, this product provides postemergence control of seedling crabgrass after germination and emergence. Postemergence control is limited to crabgrass only and is effective up to 4 weeks after germination of crabgrass. This generally corresponds to the time when

crabgrass seedlings are at the 3-leaf stage of growth and rst become visible in the established turf. This product

will not control crabgrass at later growth stages when crabgrass plants begin to tiller (spread). Properly timed applications will control existing crabgrass and prevent further emergence of crabgrass seedlings. Do not apply this product later than 4 weeks after crabgrass germination.

Control or Suppression of Other Grass and Broadleaf Weeds: For control or suppression of other grass and broadleaf weeds, this product must be applied as a preventative treatment prior to their germination and emergence. Only crabgrass will be controlled with applications made up to 4 weeks after weed germination.

FALL APPLICATION

This product can also be applied from late summer through early fall (late August through November). When applied in the fall, a sequential or second application of this product must be made the following spring to provide season-long control of crabgrass. If this product is applied in the fall, do not reseed, overseed or sprig turfgrasses within 12 weeks after application.

Tips for Improved Weed Control

• For best results, apply this product within a few days after mowing and delay mowing again for a few days

after the application.

• The turf herbicide in this product is not effective until activated by rainfall or irrigation. Performance is

improved if application is followed by ½ inch of rainfall or sprinkler irrigation. Erratic weed control may result if not activated by rainfall or irrigation within 30 days after application.

This product may be applied with drop or rotary-type spreaders designed to apply granular herbicides. For best results, apply this product evenly and uniformly avoiding streaking, skips or overlaps. Avoid the use of spreaders that tend to apply granules in narrow rows or concentrated bands. Calibrate the spreader according to the manufacturer’s directions. Initial spreader settings may require adjustment to deliver the recommended application rate under actual application conditions. The desired calibration setting may be marked or recorded for future reference. Apply this product uniformly over the treatment area. More uniformity of application can usually be achieved by applying one-half of the required amount of product over the treatment area and then applying the remaining one-half in a different direction (e.g., at a right angle to the previous direction). Avoid streaking, skips, or overlaps during application.

Check equipment frequently to verify calibration and proper functioning.
