Pre-Emergent: Dimension 2EW

Where do you get it? #

Dimension 2EW Dithiopyr Pre-Emergent Herbicide – 1/2 Gal

Why should you buy it? #

Dimension 2EW Dithiopyr pre-emergent herbicide solution is a pre-emergent you mix with water and spray. You need to use this in combination with your Barricade treatment according to the schedule. Barricade is your granular and Dimension is your liquid for that one two punch against weeds from growing. Though it’s not its primary purpose, Dimension can also act as a post-emergent herbicide for crabgrass which is a very common and hard-to-kill weed in Texas lawns.

Yes, it is extremely expensive at first glance but it is in concentrate form. You dilute it in water and use a sprayer to spread it on your lawn. This will last for so long and you will have no weeds come up if you buy this and apply it right now with a light coat. The bottle will last all year and possibly more.

What’s in it? #

Dimension comes in a 0.5 gallon bottle like this:

It is made by Dow AgroSciences which is a subsidiary of Dow Chemical Company It has been spun off as Corteva Agriscience but all the labels still say Dow AgroSciences if you get it.

The active ingredient is Dithiopyr which acts as a root growth inhibitor. It inhibits mitotic cell division as well as ends root elongation. Use the minimum rate because it does temporarily effect the Bermuda grass roots too, though you will barely notice it. Especially if you are fertilizing and watering it according to the schedule.
