  • Bonide Copper Spray

    For those of you who use the Bonide spray, do you spray only the leaves, or do you spray the branches and juvenile fruit and the mulch as well?
    l have a heavy infestation that I waited to long to start treating.
    thanks in advance

    What kind of infestation? Copper is a fungicide, and not always the weapon of choice. Many diseases have shown an ability to develop resistance or immunity to it with repeated applications.

    You would spray everything with the Copper Fungicide, Kills on contact, but has to be followed up with at least one (1) more application at 7 - 10 days to get any new growth from Spores.
    Usually many growers in Southern US just "live with it", because Rust Spores are in the environment and are carried on the wind as Dust... Good luck.
