What is the most effective herbicide for post-emergence (mid-summer) crab grass control?
We used a pre-emergence herbicide, but we still have crabgrass.
You did not mention what type of grass that you have, but our most popular crab grass control product by far is Drive XLR8. Please read the product label for full instructions and to make sure it is compatible with your grass.
