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

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 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 .

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!!

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.

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!

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 fungicide works amazing it has really done the job. We have been using it now for a few weeks just to see if it really worked and definitely a good defense for our flowers and tress. I will continue to purchase this product for sure.

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

I first off love this brand. Dead bug brew is amazing for houseplants. This is amazing for the weird fungus issues in my anthuriums inside my greenhouse, it was very very effective, the bottle didn’t last too terribly long but did work well

Loved feeling this productive from Influenster in return for my honest review! I have tried to switch to using organic products when working in the garden / yard and this product worked great! Would recommend trying!

Living on 2 acres in the country it’s hard to control pest and fungi! This stuff works really well to keep all that from ruining our flowers and garden! Thank you to influenster for letting me try this brand before purchasing anything else

This is a great natural spray that can be used in your organic garden. A very good product especially for black mold spots on your plant leaves. Usually works within a day or two. The bottle has a trigger spray which helps with ease of application and making sure you get each leaf, top and bottom. Works on Cypress Trees and Crepe Myrtle trees. I have seen great results on both types of trees in my yard. Will certainly purchase this product again.

I started a little vegetable garden in my backyard but keep having issues with white fungus due to overwatering and humidity. After spraying a little bit of this onto my tomato plant, I noticed that it did a pretty good job at getting rid of the fungus.

My lemon tree had fungus growing on it, I sprayed this and it worked like magic! It got rid of the fungus immediately and started growing beautiful lemons! I highly recommend this product.

I really like that this comes already mixed and ready to use and that it’s organic and safe to use on vegetables. Living in humid Florida I was having a problem with my mint so I was excited to use this. So far my freshly planted mint is doing good.

I ended up giving this one to a family member because I didn’t think I could use it after reading all the directions. It does a pretty good job keeping mold and other growths off of plants and shrubs without causing them to lose color or brown.

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

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 .

Works great! Very Reliable product when used as directed and easy to mix! It quickly resolved the fungal issues plaguing my garden, leaving my plants healthier and more vibrant. Amazing product

We have so many plants and I was so excited to try this. I first used this on one of our outside plants that needed help. It had lots of spots on the leaves and was look in rough shape. I did see a sudden improvement and I’m excited to see more results over time.

I have a small garden in ny backyard were I grow veggies and varies plants and some fruit trees. I used this product on some of my pepper plant and one peachtree. the product worked great on stopping the white fungus on my peach tree and helped protect my plum tree, and bell pepper plants.

My garden plants had lots of spots on them this year due to lots of rain and humidity. This spray helped! I am hesitant to spray because of the chemicals but this has better and organic ingredients

I have used this item before and I’m pretty sure it works but I’m not sure it works any better than spraying dawn dish soap on you plants I will keep using it but not sure I’ll buy it

This Product was very easy to use. The spray nozzle was easy to apply and spray. Great way to help give your plants a little extra boost of protection

I have been using this on my roses, herbs and ornamentals and I have noticed a healthy difference. I’ve seen downy mildew on my plants off and on but after I started using this I haven’t really seen anything. Good product!

This product is great! It helped my plants with some issues of rusts and my lemon tree that was getting powdery mildew.. I sprayed my plants/tree as directed and after about two weeks my plants/tree are looking better. I'd keep buying this and recommend it to others!

We grow pumpkins, zucchini, squash, watermelons and more...all of which are at risk of powdery mildew. This product has helped keep it at bay within our garden, allowing our plants to thrive!

This product works very well. I am happy I received it. I enjoyed using it on my plants. Thank you so much for letting me try this. I did not like the packaging it seemed like they know it leaks and out tape around it 

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.

I have used this brand multiple times, it is very effective. This product will not harm other surrounding plants. I like that the product is mixed together you don’t have to measure out the product.
