APPLICATION TIMING
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 first 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.
