Exceptional plant safety

Weed control only matters if turf and ornamentals continue looking vibrant after application. Dimension pre-emergent has proven exceptional turf and ornamental safety on both established cool- and warm-season turfgrasses as well as more than 440 ornamental plants. The broad label enables more confidence that the weeds, not desirable plants, are controlled.


Long Application Window- By providing both pre-and early post-emergence control, Dimension 2EW herbicide offers a longer application window than other pre-emergence herbicides, which affords more time to make applications. Applicators can confidently use Dimension from early to mid-season without worrying about switching products after crabgrass has germinated.

Application Flexibility & Non-Staining Formulations- Dimension pre-emergent can be applied to turf, landscapes, and bare ground — making it the ideal wall-to-wall solution. And no matter which formulation of Dimension is used (liquid, WSP, granule), there are no concerns about it staining your equipment or your customers’ structures and driveways yellow.

Application Rates- For pre-emergence grass and broadleaf weed control, apply Dimension® 2EW specialty herbicide as a single or sequential application at 1 to 2 PTS (0.25 to 0.5 LB active ingredient)/ACRE. Applicators may choose to make a single application or sequential applications of 1 to 2 PTS/ACRE at five- to 10-week intervals based on various factors listed on the label.

For post-emergence control, when applied at 2 PTS (0.5 LB active ingredient)/ACRE, Dimension 2EW has demonstrated crabgrass control through the three- to five-tiller stage of growth in the western, southern, and transition regions, where warm-season turfgrasses are the predominant species.

In regions where cool season turfgrasses are the predominant species, early post-emergence crabgrass control is obtained when Dimension 2EW is applied before the initial tiller stage of crabgrass (less than five leaves per plant). This stage generally corresponds with the time when crabgrass seedlings are easily observed in lawn or turf.

Do not apply this product to golf course putting greens. See label for complete directions and application instructions.

When to use Dimension® specialty herbicide

Dimension® specialty herbicide is the leading turf and ornamental herbicide providing pre-and early post-emergence control of crabgrass and other important grassy and broadleaf weeds. It can be applied before weeds emerge and early post-emergence, up to the five-leaf stage for crabgrass, when applied in areas where warm-season turfgrasses are predominant.

Dimension can be tank-mixed with Defendor® specialty herbicide and Gallery® specialty herbicide or other herbicides for an even broader spectrum of weed control. Please refer to the label for information on the other products compatible for tank-mixing with Dimension.

How to use Dimension 2EW herbicide

Choose the formulation that works best for your operation — liquid, granular, wettable powder, or on-fertilizer — and use it according to label directions for your specific region of the country and particular program conditions.

When using a liquid formulation, apply with a sufficient volume of water carrier to provide a uniform spray distribution. Be sure that treated areas receive a 1/2" of rainfall or irrigation after treatment. Granular treatments do not require immediate watering; however, best results will be obtained if irrigation or rainfall occurs within seven days of the application.

Successfully Keep Your Athletic Fields Clear of Goosegrass All Spring and Summer

Goosegrass (Eleusine indica) is a troublesome grassy weed commonly found in athletic fields such as golf greens, tees, fairway, and other turfgrasses that are mowed short. It has a prostrate growth habit and is often white and silver in the center with a wagon-wheel-like appearance. Goosegrass competes very well with warm- and cool-season turf during summer months and is most competitive in thin open turf and subjected to intense traffic or use. This warm-season annual emerges in spring or summer when soil temperatures are consistently above 60 degrees. Geography-dependent, this may be two or more weeks after crabgrass germination.

For best results, apply Dimension herbicide at 0.5 lb. a.i./A just prior to goosegrass germination and soil temperatures at 55 to 60 degrees Fahrenheit. Applying a second application of Dimension, again at 0.5 lb. a.i./A, four to six weeks later is recommended.
