Bonide Captain Jack Copper Fungicide 16 oz Concentrated Plant Disease Control Solution for Organic Gardening

Works really well. Didn't burn even the most delicate plants. For a few to be on the safe sideI just added extra water. Even treated the soil.

⭐⭐⭐⭐⭐ This antifungal concentrate works exactly as intended and does the job well for my houseplants. It’s easy to mix into a solution, clear instructions, and straightforward to use. Simple, effective, and definitely something I’d purchase again.

This copper fungicide does a good job of controlling plant diseases and keeping my garden healthier. I used it on vegetables and ornamental plants and noticed a clear improvement in preventing issues like leaf spots and blight. The concentrate mixes easily with water and sprays evenly with a standard garden sprayer. That said it does require careful use. If the mixture is applied too heavily or too often it can cause leaf burn or discoloration. Following the directions closely is important to avoid damaging sensitive plants. The bottle could also include a more precise measuring cap to make mixing easier. Overall this is a reliable and effective plant disease control product that works well when used correctly. It is a good organic gardening option but it is not completely foolproof and needs some caution in application.

I bought a spray bottle from a hardware store because I had heard good things about. It works great for fungal attacks on your tomato plants. In fact far better than anything I’ve used before. My only problem was that it was expensive and Ia bottle will treat my plants for about two weeks. It takes about a tablespoon of this concentrate to mix enough to refill the spray bottle. I can’t keep up with the amount of tomatoes my plants are producing this year. With this combined with bone meal for calcium, I haven’t had to toss a single tomato into my woods because of blossom rot. I’ve never used a more effective product and with the concentrate I suspect this will last me a couple seasons.

I am impressed. I did mix up a heavy solution. If I remember right, the instructions said to mix anywhere from 1.2 to 4 teaspoons per gallon of water. That is my biggest complaint right there! How am I supposed to know how much I need? So I used 3 teaspoons per gallon, and coated each leaf of my zucchini, front and back, very thoroughly. The next evening, I looked over my zucchini for mildew. And I couldn’t see *anything!! It was mildew free! Three days later, I started to see it again , but I have complete faith that at least powdery mildew can be dealt with!

It worked very good on my plants & garden veggies. It definitely got rid of the bugs and the fungus. very easy to use and put it in a sprayer to cover all my plants. My veggies had little to no bugs after i sprayed them. Used it every other week.

Fast shipping and product works great! HOWEVER I didn't get the measuring cup on the lid so it made it more difficult to get the right ratios. I'd give it a higher rating if I wasn't missing a peice.

The copper fungicide is a must have to rose garden, and fights against fungi disease such as black spots and powdery mildew. It's such a must have in Seattle's rainy weather. I apply every 2 weeks in grow season to my roses. One nit is it's not waterproof and can get washed off. So suggest to alternate it with one that absorbs into the plant & water proof. Alternation also helps with fungi's resistance to sprays
