I have recently received my pesticide license! I have two questions. I notice a lot of lawn care companies around NC using some type of weed killer that sprays blue. It almost looks like some kind of dye. I don't think its roundup but not sure. Anyone know the name of it?? Also, what is the best pre-emergent for centipedegrass and Bermudagrass??

Thanks!

Is it being sprayed over turf areas?

Doesn't matter where it's being used , it's a blue dye marker.

I use Blazon
