    I have used msma on johnson grass and it has worked ok I need to know when will be the best time to spray large patches of johnson grass in our fields, These are our oun and we have 100 acres with several patches some as big as a truck. I would say a few acres to "spot spray" Cattle cant eat Johnson grass that has seeded out it has been cut for hay and ingnored for years,

    Thanks Jim

    I would think in the spring, when it's growing actively, would be the best time.

    Fusilade when actively growing. Best before it starts tillering.
    May require repeat treatments
