Looking for Dithiopyr pre-emergent? This is it; we just now have it under the original brand name, “Dimension.” 

Dimension (dithiopyr)  Pre-Emergent is a granular pre-emergent herbicide used to stop invading weeds and weedy grasses in lawns. It targets most of the same weeds as prodiamine, so we typically use this in the fall if you live somewhere where longer protection is needed, but you’ve reached your yearly limit with prodiamine. In short, this works pretty much the same as prodiamine.

• Covers 6,000 sq ft (18 lb) - OR - 15,000 sq ft (45 lb)
• .19% Dithiopyr is the active ingredient
• Great for crabgrass and other grassy and broadleaf weed prevention
• Available in multiple sizes*

Product Description:

Dimension Pre-Emergent is an excellent choice to prevent annual bluegrass (poa annua), Henbit, hairy bittercress, chickweed, and other annuals if you are NOT SEEDING/OVERSEEDING your lawn.  It is a primary part of the fall strategy down south for longer protection due to milder winters. 

*Size options and coverage: 

• (1) 18 lb bag = covers up to 6,000 sq ft
  
• (1) 45 lb bag = covers up to 15,000 sq ft 

Application Information: 
The best time to apply Dimension is when soil temperatures are below 70F and above 55F. This will give you approximately 3 - 4 months of pre-emergence protection if you follow the recommended application rate of 3-4 lbs/1000.

You can use Dimension (Dithiopyr) pre-emergent in the spring or fall. However, the LCN/YM programs primarily use this in the fall for anyone who has reached their annual maximum on Prodiamine. For more information on annual limits for Prodiamine, check out the chart here.
