   I am not worried about the poa in the overseeded fwy as much as the poa in the roughs, green surrounds and around overseeded tees. I am always worried about herbicide movement into the overseed from heavy rains. We are always very clean up until late March and then it seems overnight we look like we never did anything over the winter. We pre-emerge around greens and approaches, spray roundup if we are ever dormant and use revolver to spray what we see come up by mid December. We may be dormant for a week? then it usually warms up and we break dormancy. I know that we are not closing all our windows for seed germination but what are some of you using with any success?

   Scott,
   
   I'm going to throw this out there as I just had some interesting results... with Trimec Classic.
   
   Sprayed some spots here an there in our common bermuda rough in the first part of April... here in AZ, our Poa is going to town at that time and we'd usually do something well beforehand (i.e. light rate of glyphosate). Went out at 3.5 pints per acre and left those spots sticking out like a sore thumb... almost looks like we hit them with some ammonium sulfate (but we don't do anything on roughs but one app of chicken in late spring).
   
   It's got me doing some serious thinking about moving some money from fert to chem for next year...
   
   If anyone has thoughts on this, I'm all ears!

   Have you tried Prograss?

   Prograss will severely stunt any Bermuda that is semi-dormant. It's actually used here in Florida to remove Bermuda from St. Augustine. Not sure I would risk it with other tools on the market.
   
   Revolver is a great product but very temperature dependent. Applying with cool temps significantly delays control. May even not do anything in prolonged cold spells.
   
   If there has not been signs of herbicide resistance to Simazine, it can be used successfully to remove, and prevent further Poa populations on dormant and even semi-dormant bermudagrass. However, repeated use of this product can and will build resistant plants. You can consider throwing this in the tank with your Round-up, or substituting with Barricade for pre-emergent control to get you past that early spring germination period.
   
   Katana has shown really good results for Poa post emergent control. Slightly higher than the price of Revolver, but quick acting and effective.
   
   A cool trick I learned recently was guys applying Reward in their roughs for Poa control. Will most definitely burn your green Bermuda out, but will kill any weeds present as well. The burned out rough provides awesome definition against the green overseed. The Bermuda greens back up within a few weeks with no harm. Instead of waiting until the Poa gets nasty, apply a few weeks earlier to get the plants while small and Bermuda is still somewhat dormant.

   Add Barricade to your sprays to get you through the later germinating periods. I usually spray Simazine and Barricade together. Clean as a whistle.

   Scott, I am going to try a 2 x 12oz/Acre spray of Trimmit this September/Octover about two weeks apart and try to kill it when its young. I have a salesman who says that's the ticket. We will try and get our overseed out early at the end of August and spray our first spray after our 2nd mowing. Wish me luck!
