Thanks, really had a hard time identifing this, and was not sure what it was. I thought it was crabgrass but MSMA really was not doing much to it last year. My yard is too big to spot spray. Will 24D take care of the goosegrass later in the year?
There is also Dallasgrass that looks like crabgrass. MSMA contains arsenic. Be careful with that stuff. I thought it was going to be banned, but I don't know if that has happened. Btw, 24D doesn't work on grassy weeds, only broadleaf weeds.
"24D affects broadleaf weeds and not grasses because the two classes of plants transport chemicals differently through their leaves. Broadleaf weeds have their growing point at the tips of the leaves. Grasses grow from their base."
