Too much MSO?

    I think I may need to back off the MSO in 90plus weather. I have been using 4oz per 8gal in my PG Ultra [with Celcius] but this time I have some yellowing and you can really tell if my overlaps were to close or to far apart this time.
    I guess the good thing is that even areas that had some Nut sedge quit growing and is browning.

    2 1/2 oz of MSO in 8 gallon of carrier is plenty.

    Yea I really wasn't thinking. I generally go 4oz in the cool spring weather and back off to 2 when it heats up. The couple that got some Certainty added into the Celcius mix should have the Sedges gone pretty quick, unless it burned them too fast for the Certainty to work.
