Customer Reviews for Bonide Captain Jack's Copper Fungicide, 32 oz. Ready-to-Use Spray for Organic Gardening, Controls Common Diseases

[This review was collected as part of a promotion.] I love Bonide Copper Fungicide and use it on my flower farm. So when Influenster had this sample product up for grabs I was thrilled! It’s straight forward and easy to use, organic in moderation, and is safe for bees and other pollinators—just spray early in the morning or late in the evening so it can dry in the off hours for pollinators. I especially loved this sample as it’s premixed and in an easy to use spray bottle. It’s perfect for small jobs. Normally, I purchase the concentrated bottle and mix it in an industrial sprayer. It goes a long way and for the price, amount, and the efficacy of the product it’s a great deal. Both options serve individual purposes. Summer before last it was a damp and humid summer with lots of powdery mildew, black spot, and blight on my zinnias, roses, and new peonies. For the zinnias, the copper fungicide greatly slowed the spread—it was inevitable with the amount of rain we had, but it lengthened their life and grow time. As for the roses and peonies, it stopped their issues quickly. Black spot on roses is a huge issue for me in a humid climate and nothing has worked until Bonide copper fungicide. It’s the reason I snapped up this bottle as quickly as I could. It works and it’s safe! The health of my plants greatly improved with the use of this product and I’ll forever keep it in stock on my farm.

[This review was collected as part of a promotion.] This product actually took black spot from my vegetable tree as well as powder mildew. The bottle is nice snd has a rubber which prevent it from leaking. I recommend .

[This review was collected as part of a promotion.] I had recently noticed that some of my houseplants 🪴 were displaying signs of leaf rot , so when Influenster sent me this product, it was perfect timing!! I’ve tried it out on various plants in my home and I’ve definitely noticed an improvement. They’re growing new leaves and are looking spiffy. This product is also intended for outdoor gardens, fruits, and flowers 🌸. I do recommend it!!

[This review was collected as part of a promotion.] I have a flower garden right next to our pool and every year several flowers get mildew and dark spots. This time I sprayed this fungicide as soon as I received it and so far so good!! Very pleased with this product.

[This review was collected as part of a promotion.] I was excited to try this product, but looking at my garden and houseplants, I don't currently have any plants with fungal infections. It sounds like it can be used preventatively, but it needs to be applied under certain conditions (temperature/weather). I will definitely use this on my garden if signs of fungus develop, but it sounds like you don't want to overuse copper-containing products because it can have downsides. I like that it's safe enough to be considered acceptable for organic gardening! Overall seems like a good product!

[This review was collected as part of a promotion.] When your plants have issues, including the powdery mildew that many of mine get, this spray is ready to go. Easy to use and effective for a few different ailments your plants may experience.

[This review was collected as part of a promotion.] I have a peach tree and since we moved I noticed something was off with it but never really do anything. Recently one of my neighbors told me it was fungus what my tree had so I started researching what I could do but almost at the same time I got this product so I figure I’d give it a shot and by using it as the label states I’ve noticed a lot of improvement however I want to see how it will do for a longer period of time

[This review was collected as part of a promotion.] I started a little vegetable garden in my backyard but keep having issues with white fungus due to overwatering and humidity.

[This review was collected as part of a promotion.] I like that this product can cover a large amounts of issues you can find in your garden for your flowers and vegetables. I used this on the powdery mildew that my bee balms had, after 2 weeks they cleared and looked much better. It seemed to do a great job of preventing more issues within my vegetable garden. Will test more in the spring

[This review was collected as part of a promotion.] My hydrangeas have a fungus called Cerospora (spotted leaf fungus). You can see in the pictures that it did help with the spots but left the leaf silver and a little dried out. In all fairness I am testing this in the fall and plan to use this again in early spring. I plan on cutting the hydrangeas down and using this in the dirt where the fungus begins .

[This review was collected as part of a promotion.] I love this stuff. It took about a week to see results but I definitely see a difference. I was concerned for a bit as to if it was going to work or not but it came through and started to clear up the black spots on my tomatoes. I plan to purchase more when this bottle is empty.

[This review was collected as part of a promotion.] This copper fungicide spray works well on plants. It is natural and can be used on organic garden. A few of the plants had some dark brown spots and white mildew. We sprayed it daily and it worked very well. Not much mildew left. We will apply more to completely eliminate all mildew and dark spots. The spray is easy to use. I will buy more to use it in spring for veggies.

[This review was collected as part of a promotion.] My husband was just researching how to save our blue torch cactus from what appears to be fungus, and the Captain Jack’s Copper Fungicide arrived.

[This review was collected as part of a promotion.] I got the ready to use spray and it’s awesome. My roses get the powder mildew and I finally found a product to treat it. The instructions are clear and easy just make sure you repeat the treatment every 7-14 days or after a downpour. I am looking forward to using this for my veggies and flowers in Spring.

[This review was collected as part of a promotion.] It has finally been raining here after a hot summer in Texas so that means the plant mold has returned. This product has been a plant-saver for my roses! It is not harsh and you don't need a lot to get the job done. 10/10!
