That's exactly it - it's great for SA due to the higher salt tolerance.
Official instructions are to make sure the crabgrass is wet, then DUST (as in, lightly dust, not big ole clumps of powder) the weeds. Others are saying it can be sprayed, etc. I have 2 kinds of crabgrass in my yard, at least. Don't care about the CG in the lawn - green grass isn't a status symbol for me. But when I can't see the woodchips for the crabgrass, I get grumpy. So one of these mornings when it's not 40-soemthing degrees out, I'm heading out when it's still dewy and testing it on one of my beds..
