This product is a herbicide that provides control of crabgrass and other annual grasses and broadleaf weeds in established lawns and ornamental turfs, including golf course fairways, roughs, and tee boxes. This product will not harm nearby established ornamentals when used according to label directions.
DIMENSION (dithiopyr) provides season-long pre-emergence post control of the toughest grasses as well as controlling more small-seeded annual broadleaf weeds than any other herbicide. DIMENSION can be used as a pre-emergent before crabgrass germination, or as a post-emerge application up to 3 leaf tillering. When it comes to weed prevention on golf courses, DIMENSION provides a wide range of application options (spring, summer, and fall) and controls poa annua along with 25 other tough grasses and broadleaf weeds.
Weeds controlled include:
- Bluegrass, Annual
- And other listed weeds
Control of Crabgrass
- This product provides "pre-emergence" control of crabgrass (including the large, smooth, and southern species) when applied prior to the emergence of crabgrass from the ground in established lawns and ornamental turfs.
- It can also provide "early post-emergence" control of crabgrass during the early stages of crabgrass growth after the crabgrass has emerged from the ground. However, it is often difficult to see the very small, early stages of crabgrass in well-established lawns and ornamental turfs. Post-emergence crabgrass control will be obtained only when this product is applied prior to the tillering of crabgrass, which generally corresponds to the time when you can first easily see the crabgrass plants in the lawn or turf. So the practical benefit of this product's additional, early post-emergence activity is that (compared to strictly pre-emergence crabgrass products) it can give the user a 2-4 week longer period of time to make applications and still control crabgrass.
