Bill from Dothan, Al writes

Can Prodiamine 65 WDG be applied shortly after Atrazine has been used on St. Augustine?

I applied Atrazine a week ago to my St. Augustine and Centipede lawn. Can I follow up this week with Prodiamine 65 WDG?

Answer:

If you were spot treating on your St. Augustine with Atrazine as a post-emergent herbicide, then it should be fine to apply the Prodiamine anytime after that application. If, however, you were applying the Atrazine as a blanket application as a pre-emergent, then you would not need to use another pre-emergent right away.
