  • Asked by Russell from Summerland Key, Fl 33042
    06/17/2014
    Q
    How much Diquat do I mix with 1 gallon of 1.5% Roundup solution to get 1 hour rainfall protection??
    I have a 2.5 gallon of older Roundup concentrate 41% and would like to make the application rain proof by adding Diquat as thunderstorms come up over night without much notice.
    A

    RoundUp products are generally rainfast within a few hours so that is not really an amount of Diquat that we could recommend to make it rainfast any quicker.  The amount of Diquat you use per gallon of water is dependent on what you are treating for.
