   Guys,
   
   I have bentgrass approaches that have bermuda encroachment. I plan to begin using phylex next week. Sales rep. recommended 1/4 oz. per acre with 1 oz. trichlophr. Anyone playing with this program? Bent is cut at .450. Thanks.

   University of Missouri did a study in 2013 on bent grass fairway height, it is program 9. Sorry I'm not more technosavy, or maybe I could have just posted that article. I remember the one thing they mentioned was how the bent grass went off color and a lot of places wouldn't find it acceptable. But it defiantly took out the Bermuda and the bent came back.

   I did a trial with it down here in Florida looking to clean up the common Bermuda that was encroaching into our TifDwarf nursery green(rate was a glug, glug into a 1 gallon pump-up). It smoked the common and TifDwarf, but then the weirdest thing occurred - the TifDwarf started coming back while the common was gone! Now I'm not saying for guys to use this for encroachment on their Bermuda greens as it was very ugly for 6-8 weeks. I was just astonished that it killed one Bermuda, but not the other.

   Your rep is correct. I would not add the triclopyr. Triclopyr masks some of the bleaching but adds a little more stress to the bent in hot weather. You need multiple reps, still time this year for a couple apps 3 weeks apart. You are going to turn those approaches snow white but the bent will green-up again in 10-14 days. Good luck.

   We have used it on our bentgrass practice tee at the .25oz/A rate for the last couple of years to clean up goosegrass. I always add .75oz/1000 of Drive XLR8 to the tank and it keeps the bent from bleaching out.

   Guys,
   
   Just to give an up date. Last friday I made a .25 oz/A application of Pylex with 0.5 oz./M Drive onto my bent approaches. Today the bermuda is bleach white and the bent appears to be doing well. I am doing to try this again next Thursday and up my rate of Pylex slightly. This stuff could be a nice tool for goose and bermuda in bentgrass if we can all figure out the rates, timing of reapplication and how far apart to make the applications. Impressed so far but know if I lay off the bermuda will green back up.

   Have seen it take out mature goose at .1 oz/A. Have gone as high as .5 oz/A on Bent fwys without damage if conditions are right. Will play with adding triclopyr to pylex this fall once things cool off to see if increase harm to Bermuda. This has been a game changer to those of us wanting to remove Bermuda from Bent (and Fescue).

   I forgot how to post pictures here. Trying to attach a word file with a picture. Bermuda greens back up but Keith is right, goose gets hammered.

    Wow Ken. Looks like a lightning strike! How quick did the Bermuda green back up?
    
    @Jeff - looked at the photo. Is that goose?

    No, that is bermuda in bentgrass. Goose is even more sensitive. Small goose dead with one application. Large plants take a couple. You florida guys be careful. Bermuda bleaches heavily. Even with trichlophr added.

    If that is goose in bermuda put trichlophr in the tank instead of drive. It will help with the bermuda bleaching out.

    Here is a trial I did last summer. It was a driving range fairway, rye and bent, heavily infested with common bermuda. You can see what Jeff is talking about. Drive and Turflon take away some of the bleaching from Pylex.

    For those who have already played with taking bermuda out of bent...Pylex or Acclaim? I know we have phyto with both so I am on the fence. Can you mask the bleaching of Pylex with pigments or dormant turf paint? Thanks.

    Based on a class I took at the GCSAA Conference, using Topramezone (Pylex) to control goosegrass in bermuda fairways, they saw 90% control (Pylex 1 fl. oz./acre + MSO) 50 DAT. Bermuda bleaching lasted about 28 days.

    Anyone tested on green HOC? would be interesting to see. I am sure its not labeled for that HOC. 419 encroachment into Crenshaw being the issue with us.

    Guys,
    
    I am going to make the second app to my approaches on Thursday. This will be 13 days after the first. Bermuda is already becoming less bleached. I will repost when results begin. Bent is doing great after first app. Temps have been around 90 in southern indiana.

    Our second application was made to our bent approaches today. We switched from adding Drive to the tank to a very light rate of Trichlophr. This is suppose to do better with the bermuda bleaching. The second app. was 13 days after the initial. This seems to be too far apart as the bermuda was coming out of it bleach symptoms. Our third app. will be 10 days from today. I will repost with injury results next week. Pylex seem to be a great tool for both goose and bermuda removal from cool season grasses.

    Fellow professionals,
    
    My second Phlex application took two days longer to show turf injury. Using the Trichlophr defiantly removed all bleaching signs. The bent seems to be bronze in color which was not the case with Drive as the mixing partner. The bermuda is yellow and not white. This spray was applied to green height turf with no injury. I am going to stick with the Trichlophr mixing partner because it removed the bleaching. I am going to make my third application 10 days from my second. Seems to be working if I stick with it.
