I am now using revolution 5oz + dispatch 1oz with no excessive drying out. The only negative is that this combo seems to hold a little too much moisture at the surface. I am going to continue my search for the perfect moisture distribution product(s) next season. Maybe cascade+revolution?
Dru, what is your irrigation practice after the Revolution app? I have heard and have seen in practice that a Revolution app has to be watered in with at least 1/3 " of water to push it evenly in the profile. We are different though, bent on USGA spec (well there are 4 soil). To light on the irrigation and the Revolution stays up near the surface and keeps it a little too wet on top.

This is subject to change but as of now I run 4min + 4min (to avoid runoff)after app and run a 10-12 min cycle that night. Sometimes less depending on the forecast. Do you think this is too little water? USGA greens.
Dru, I remember having a poster for the different products that Aquatrols makes, but didn't see it in the break room. But you might try pulling up this address
http://www.aquatrols.com/turf/golf/prod ... LOCALE=USA and clicking on the Revolution Users Guide with give you details about irrigation following application.
As far as how many minutes to run your irrigation, I have Rain Bird 51's w/20 nozzles on most greens according to my Stratus II, if I want .33 " of precipitation I need to run those heads for 27 minutes, on my greens where I've changed out and installed 900 heads with 60 nozzles I only have to run heads for 19 minutes, so that run time depends on your nozzles and spacing. But my guess is your not running your heads long enough. I don't know either how the dispatch or Cascade might affect Revolution under those irrigation practices.
I don't run any heads myself until that evening, I'm afraid, (but I am not sure if it's true) that once I run a little water on the Revolution it will just move into the thatch layer and then get tied up and the later irrigation will not move it into the soil. Because of that fear, I will even disable my cycle and soak program, (or what I do is ride around and turn on my greens with the radio for 30 minutes cycles and it over rides the cycle and soak program). This is on bent in the transition zone in 90 degree + heat and I've never seen a burn problem. The one thing I don't do per label is put it out in 2 gallons of water per 1,000. I use 1.5 gallons of water per 1,000.
