    Around mid sept. we applied a liquid 20-0-3 fert with surge herbicide. This is the first time we have used Surge. Needless to say only certain lawns had gotten tip burn almost exactly a week later . Has anybody ever had this problem? Fert or Weed control? any suggestions.

    I can speak only for Warm Season C 4 turf. Tip burn is generally caused by just a little too much Nitrogen. The first mowing will remove that tip burn.

    Too much Herbicide will generally cause more stress than just a little tip burn and one mowing will not remove the problem.

    Anybody who sprayed lawns has burned at least a little turf at some point. It happens.
    What was your dilution rate? (gallons/1000)
    We had a problem with our backflow valve for a while. We were getting a big pressure buildup in the hose when you weren't spraying. A big surge of material would come out at first. The beginning of all of my passes were all burnt. They came back, but it still looked bad. We fixed the valve and went from 2 to 2 1/2 gallons per k. Your lawns should recover.

    The weather conditions the day you sprayed also can be a factor. In warmer weather, the burn chances increase. Especially if the turf is not irrigated within 24 hrs.

    You probably used NIS (sticker) with the surge, which made the N more likely to remain on the leaf surface.
