Mike from Newtown writes

Can I apply Hi-Yield Atrazine Weed Killer immediately after seeding?

I am pretty sure I can, but wanted to be certain. Can this be applied immediately after broadcasting Switchgrass seed? Big Bluestem?

Answer:

Hi-Yield Atrazine Weed Killer or any other post-emergent should not be applied until grass is established. Generally until the lawn has been mowed 3 times. Atrazine also states to not seed until 6 months after application as it is also a pre-emergent.  It is only for use on Centipede and St Augustine turfgrasses.
