What Pre-emergent

I have a bermuda lawn & just recently started getting a little greening…only problem is that so far it is all weeds!

Does that mean I am too late for pre-emergent? If not, what do I need?

If too late, what do I need? It is mainly grass type weeds & what kind of looks like clover.

I am in NW Louisiana

Thanks for the help!

What & when do you normally spray for the crabgrass?

Oxidiazon (Ronstar) will be your best pre-emerge to use for crabgrass and goosegrass control in the summer but should go out now. If you have broadleaf issues, I would use Prodiamine (Barricade) in conjunction to the oxidiazon. Using the proper rates on the label is key. Be sure to calibrate your spreader properly for best results.

Never to late to apply a pre-emergent in my opinion. Of course applying at the right time gets you the most benefit.

Soil temp will ultimately dictate if a preemergent is effective, thus yearly timing is so important.
