    I want to apply MSMA to my home lawn.(Bermuda)
    Instructions on the bottle say to mix 1.5 oz to 5 gallons water to treat 1000 sq ft.
    My spray tank is a 15 gallon pull behind and my front lawn is 10,000 sq ft.
    I know from spraying liquid iron that I can cover 10,000 sq ft @ 40psi with 15 gallons,running the mower pretty quickly.
    My question is:How in the world do I calculate the amount of MSMA for a 15 gallon tank on 10,000 sq feet?
    If I use 5x 1.5 oz per 5 gallons,I believe it's going to mix too strongly.That would be 22.5 oz per 15 gallon tank and I would then be applying 1.5 oz per 1 gallon.
    Anything I can do besides spraying 3000 sq feet at 15 gallons at a time?

    we have used MSMA at the 1.5 oz per gallon without insident.

    But keep in mind that we are dealing with cool season turf unlike yourself. I know nothing about bermuda lawns.

    Or go the 5 gal/1000 rate you'll just have to practice with water and a slower travel speed...but that shouldnt take to long.

    Thanks TSM.I think I'm going to try 1 oz per gallon and spray at 30psi.Heck,if I kill it,it's only my own.Been racking my brain all day on this one.
    Thanks again!

    We use 1/2 oz per gallon during this time of the year. It yellows the grass alot if you use any more. But its your yard so it doesnt really matter. If you want a better kill put some sticker in with it. When it cools down you can go hotter.

    I don't mind it yellowing the bermuda.I'm in no hurry to replace 10,000 sq ft of sod though.Thanks!
    Just FYI,I did mix about 1/2 cup to 1.5 gallons in a hand sprayer and played with it in my backyard.Killed everything,but the bermuda survived,although quite stressed.Even killed the tall fescue.
