Preemergence control of summer annual grasses in turf, including bentgrass, landscape beds, container and field nurseries. Postemergence control of crabgrass is possible when applied before crabgrass has tillered.
|Amount of Active Ingredient||Amount by Formulation|
|2 EW||40 WP|
|Per Acre||0.5 lb||2 pt||1.25 lb|
|Per 1,000 sq. ft.||0.73 oz||0.46 oz|
|Note: Different rates of application are recommended for turfgrass applications. In NY, max application rate is 0.25 lb ai/A.|
Preemergence control of crabgrasses, goosegrass, other summer annual grasses, annual bluegrass, lespedeza, bittercress, chickweed, oxalis, henbit and parsley-piert. Higher rates are needed for goosegrass and broadleaf weeds. Partial control of spurge, longstalked phyllanthus, and rice flat sedge. Postemergence control of smooth and large crabgrass if applied before tillering.
Weak on many broadleaf weeds including groundsel, eclipta, chamberbitter, spurge, pigweed, and prostrate knotweed. Does not control nutsedge or perennial weeds from rhizomes or stolons. Does not control goosegrass postemergently.
Follow label directions and local Extension guidelines for recommended rates for your area. Apply before weeds have emerged. Irrigate after application to incorporate the herbicide. Two applications are generally necessary for full-season grass control. An emulsifiable concentrate (EC) formulation is also labeled but is generally not recommended for landscape uses due to volatility and odor concerns.
In landscape beds, apply Dimension as a directed application, avoiding contact with the foliage of ornamental plants. Over the top applications when plants are in active growth will injure the foliage of many ornamentals. Over the top applications to some annual bedding plants has reduced or delayed flowering.
Up to 12 weeks of residual annual grass control is observed in turf or field soil. Length of residual weed control is less in containers. Two applications are necessary for full-season grass control.
Moderately-high volatility, especially with the EC formulation. Incorporation via irrigation is necessary. Leaching is negligible.
Inhibits root growth by blocking cell division in a manner similar to the dinitroanaline herbicides, but the exact site of action is different. Symptoms include swollen root tips. HRAC Group K1; WSSA Group 3.
