Q&A Home

Gary from Newton, North Carolina writes,

Is there any benefit to alternating Barricade and Dimensions2EW every other month in North Carolina foothills?

We have had much difficulty controlling crabgrass and dallis grass. I understand they are different. Just looking for the best combination of pre-emergents.


Barricade and Dimension are actually in the same class of herbicides which means they work with the same mode of action and there would be no benefit to switching between them. We would recommend Barricade because it lasts longer and you will get great control with just Barricade. If you have current weeds (though you should be ahead of the game at this date) try Monument, it will do a great job.
