    Q: Can I use a hose end sprayer to apply

    5 months ago
    1 Answer
    • Team Bonide
      A: Dial hose-end sprayers can be used to apply pesticide concentrates, such as Captain Jack's Copper Fungicide. The dial should be set based on the desired mix rate per gallon of water, typically in a range from 0.5 oz (1 tbsp) up to 2 oz (4 tbsp) per gallon, depending on whether the dial measures in ounces or tablespoons. If more precise setting guidance is needed, please feel free to reach out to consumercare@bonide.com with what type of plants are being treated, where you are located, and the disease you are trying to prevent or control.

    Works Great on a Texas Fig with Rust

    4 months ago
    Treated a Texas Brown Fig tree, Celeste, that had fungus all over. I learned what was going on and cleaned up every bit of the old leaves as they dropped. As winter set I used Capt Jack's, about 3 ounces in a 32-ounce spray bottle with distilled water, four or fives times about 12 days apart. Today that sick little tree is growing off! Bright green with figs no 'rust' [fungus]. That is for sure because of this product.

    Yes, I recommend this product.

    Great product, but TSO fails in many ways

    7 months ago
    Order on Sunday for same day delivery - to be delivered on Monday. They sent to wrong store. Took another 3 days and 5 phone calls - 2 that were NEVER answered at TSO admin. It's like TSO is run by junior high students. They drop the ball too much...Finally received it Thursday - with no apologies and no $5 credit for the crap they put me thru..

    Yes, I recommend this product.
