Q: Can I use a hose end sprayer to apply

3 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.

Q: How much per gallon of water

10 months ago
1 Answer
  • Team Bonide
    A: 0.5 oz. up to 2 oz. of Captain Jack's Copper Fungicide Concentrate per gallon of water. The lower end of the range can be used as a preventative treatment as new growth is emerging. Mid-range is generally used when disease pressure is high or when disease is first noticed. The higher end of the range can be used during dormancy or when growth is mature, and disease pressure is high for tomato plants.

Works Great on a Texas Fig with Rust

2 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

5 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.
