I'm becoming a big fan of MSMA. I bought some Target 6.6 from JDL and it's proving to be quite beneficial in the bermudagrass vs. crabgrass. But I do have a few questions being how this is my first year of spraying post-emergent herbicides. 1. What's with MSMA regarding environmental concerns? Is it not true they can't make MSMA anymore? If so, why? I was told once it's all gone, that's it. 2. Is there anything else comparable for crabgrass control in bermudagrass? It appears Q4 will possibly be labeled for bermudagrass and of course, there's Drive, but in my opinion, they're no better but more expensive.
