   Looking for info on Tupersan. Rates? Timing? Application methods? Etc. I'm on bentgrass in the middle of Oklahoma. Getting bermudagrass on my edges and looking to clean them up this fall. Is there a better product out there? Any advice would be great. Thanks

   Tupersan seems to work better when applied 2 consecutive times at max label rate just before the expected 1st frost in your area and again in the Spring when the bermuda is expected to come out of dormancy.The cost is quite high for that method,though. I keeps the bermuda fron 'tacking down' and spreading but won't kill the existing encroachment.
   Why not try Acclaim at a very low rate....say 3 to 5 oz/acre every 2 weeks over the course of the summer?

   Investigate trimmit apps in the late summer early fall, not only will it help with poa but well timed apps in the fall when the Bermuda is trying to take in carbs to get through the winter, trimmit can make it weak enough to give out and help with the next spring.

   Larry,
   
   I will be attending the Clemson Turfgrass field day one week from today and this very topic is on the agenda to be discussed. I'll let you know what I find out.

   LT, we sprayed tupersan to slow the encroachment on edges. Used a pump up sprayer and mixed one pound per gallon, sprayed the encroaching bermuda on the bentgrass and followed directly behind with a hose and lightly watered it in. I hated it, it was very messy and always clogged the nozzle, turned grass white and didnt seem to work all that well, especially for the cost. I dont use it any more but would like to find something to help, guys have been edging greens this week since we have no water and therefore nothing to mow or weedeat...

   Dr. Scott McKelroy at Auburn recommended spraying the morning after the first night in the 40's and then again 10-14 days later. Then hit it two times again in the spring as the bermuda breaks dormancy. He said you might spray it three years with it doing nothing (or very little) and then one app might take it all out. Or, your first app might take it all out. He said they can't really figure out why it is so inconsistent, but he believes if you keep at it you will have an app work sometime. I block off all but two spray hawk nozzles and put two tee jet off center nozzles (8008OC I think) on the two that are open. This gives the perfect width and it sprays straight down on both sides. The also have granular Tupersan now that supposedly works just as well? I think the acclaim program can work, but I have seen it ding bent pretty hard.

   Larry,
   
   I didn't find out anything groundbreaking on this subject. A new chemistry, Metamifop, was being tested with some positive results. I personally thought the Tupersan results were just as good if not better. Never completely killed the Bermuda though, just shut it down. Be careful on weak or stressed Bent. Both products appeared to have an adverse effect on their plots. Props to Clemson for another very informative field day.
