How much Roundup Pro Max will i need to kill a 3.5 acre field filled with grasses and weeds?

Should i spray now or in spring before soybean planting?


You will need two 1.67 gallon jugs of Roundup Pro Max to kill all vegetation on 3.5 acres. Simply mix 2 oz of RoundUp Pro Max per gallon of water for most applications. Roundup Pro Max does not provide long term control so we would recommend treating two weeks prior to planting.
