What Is Dimension 2EW?

Dimension 2EW is a liquid formulation of dithiopyr, a Group 3 herbicide. The product contains 24% dithiopyr, equivalent to 2 pounds of active ingredient per U.S. gallon.

Dimension 2EW is primarily used as a preemergence herbicide. When applied at the appropriate rate and timing, it also provides early postemergence control of crabgrass.

The product is designed for use on established turf and a variety of other approved sites. Always read and follow the current Dimension 2EW label before mixing or applying the product.

Dimension 2EW for Crabgrass Control

Crabgrass is one of the primary target weeds for Dimension 2EW Herbicide.

Dimension provides preemergence crabgrass control when applied before crabgrass becomes established. It also provides early postemergence control when crabgrass is still within the growth stage specified on the product label.

Dimension 2EW can provide early postemergence crabgrass control through the five-leaf stage when applied according to label directions. 

Proper application timing is important for effective crabgrass control. Preemergence applications should be made before target weeds emerge, while early postemergence applications must be made while crabgrass is within the appropriate growth stage.

For specific application rates, timing, turf restrictions, and other requirements, always refer to the current product label.

What Weeds Does Dimension 2EW Control?

Dimension 2EW is labeled for control of a broad range of annual grasses and broadleaf weeds.

Depending on the application and use site, listed weeds include:

The complete list of controlled weeds and the applicable use rates can vary by application and must be confirmed on the current product label.

Dimension 2EW for Lawns

Dimension 2EW can be used on established lawns when the turf and application are included on the current product label.

The herbicide is labeled for use on established cool-season and warm-season turfgrass. Approved turf uses include residential and commercial turf as well as other professional turf applications.

Dimension 2EW can be an effective part of a lawn weed-control program when applied at the correct rate and timing.

For best results, identify the target weed, turfgrass species, application site, and appropriate application window before treating.

Dimension 2EW for Bermudagrass

Bermudagrass is among the turf types associated with labeled Dimension 2EW applications.

Dimension 2EW can be used as part of a preemergence weed-control program on approved established bermudagrass areas. Application rates and timing depend on the target weed and the specific use.

Always verify the current label before applying Dimension 2EW to bermudagrass or any other turfgrass.

Dimension 2EW for Tall Fescue

Dimension 2EW is also labeled for use on approved established cool-season turfgrass, including tall fescue.

For tall fescue lawns, Dimension 2EW can be used for preemergence control of listed weeds when applied according to label directions.

Because turfgrass tolerance, application rates, and timing can vary, always check the current product label before treatment.

Preemergent Weed Control With Dimension 2EW

Preemergent herbicides are generally applied before target weeds germinate and become established.

Dimension 2EW forms part of a weed-control program designed to prevent susceptible weed seedlings from becoming established. Application timing is particularly important for annual weeds such as crabgrass.

Corteva recommends applying Dimension 2EW for preemergence grass and broadleaf weed control according to the labeled application rate and timing for the specific region and program.

Environmental conditions, turf species, target weed, geography, and application timing can all affect results.

Early Postemergence Crabgrass Control

One of the features that distinguishes Dimension 2EW from many preemergent herbicides is its early postemergence activity on crabgrass.

When applied at the appropriate labeled rate, Dimension 2EW can provide early postemergence crabgrass control while the weed is still young. Corteva identifies applications through the five-leaf stage under the applicable conditions. 

Once crabgrass has developed beyond the stage specified on the label, control may be reduced. Always follow the current label for the appropriate application timing.

Dimension 2EW Application Rate

Application rates for Dimension 2EW depend on the target weed, turfgrass, application timing, geographic region, and specific use site.

For preemergence grass and broadleaf weed control, Corteva lists an application range of 1 to 2 pints per acre for Dimension 2EW, with specific rates and application programs determined by the label.

Do not use a single application rate for every lawn or weed problem. Always consult the current product label for the correct rate for your specific application.

Dimension 2EW Application Timing

Timing is one of the most important factors when using a preemergent herbicide.

For preemergence control, Dimension 2EW should be applied before the target weeds emerge. For early postemergence crabgrass control, applications should be made while crabgrass is within the growth stage specified on the label. 

The ideal application window varies depending on:

• Location
• Soil and weather conditions
• Target weed
• Turfgrass species
• Application timing
• Previous weed-control treatments

Local growing conditions can significantly affect crabgrass emergence, so always use the current label and local turf-management recommendations when determining application timing.

Dimension 2EW Irrigation and Rainfall

Proper watering after application can be important for preemergence herbicide performance.

It is recommended that treated areas receive 1/2 inch of rainfall or irrigation after treatment for the applicable liquid application.

Always follow the current product label for irrigation requirements and restrictions applicable to your specific application.
