Dimension 2EW Herbicide

Dimension 2EW Herbicide, manufactured by DOW/CORTEVA, is a selective Pre-Emergent Herbicide that provides control of Crabgrass and other annual grasses and broadleaf weeds in established lawns, commercial sod farms, ornamental and sports turf, container-grown ornamentals, landscape ornamental and non-cropland.

Dimension will not control currently visible weeds except crabgrass in the early stages of growth. It is best applied before the weeds begin to pop up. Dimension 2EW is highly recommended to keep problematic weeds from creeping up every growing season, especially for crabgrass and many other labeled invaders.

Tools Needed:

You will need to use a handheld or backpack sprayer. 

How to Use

• Step 1: Determine how much Dimension 2EW Herbicide to use by measuring the square footage of the treatment area. To do this, measure the treatment area's length and width in feet, then multiply them together (length x width = square footage). Dimension 2EW can be mixed between 0.5 and 0.73 ounces per 1,000 sq ft in 1 gallon of water, depending on the weed. The exact rates per weed are on the product label.
• Step 2: Fill the sprayer halfway with water, then add the product and any surfactant or spray dye. Close the lid to your sprayer and gently agitate the container. This will mix the solution for an even application. Once you are done agitating the sprayer, you must fill in the rest with water and stir again. 
• Step 3: Apply the product according to the labeled directions in the area where the weeds are. Spray using a fan nozzle spray setting for even coverage.

Where to Use

Dimension 2EW Herbicide can be applied in established lawns, commercial sod farms, ornamental and sports turf, golf course fairways, roughs, tee boxes, container-grown ornamentals, landscape ornamental and non-cropland, natural areas, and Christmas trees.

When to Use

You will want to apply before the weeds germinate and become visible. This time frame can vary depending on your location. For the southern states, it falls typically between January and March. In the northern states, it usually falls between February and May.

You should aerate your lawn before applying a pre-emergent solution but do not do this after the pre-emergent application.

Aerating the lawn after applying the pre-emergent can break the seal over the ground and around the seeds, making the pre-emergent less effective. We will also check the soil temperature using a soil thermometer. The pre-emergent will need to be applied before the soil reaches 55 degrees. Temperatures higher than 55 will allow the unwanted seeds to germinate and grow.

Safety Information

Dimension 2EW Herbicide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product. 

Keep people and pets out of treated areas until the sprays have dried. 

Special Considerations

Dimension Herbicide is best applied on well-established lawns. Newly established turf will need a sound root system and a uniform stand, as well as having received at least two mowings following seeding, sodding, or sprigging before making the first application. Using Dimension 2EW on turf that is not well established or has been stressed or weakened may result in turf injury.
