Ready-to-Spray Copper Fungicide

Our arborist (i.e. tree guy) told us we had a fungal rot spreading through our trees killing them. He suggested we try this product versus other more expensive methods that could cost us $1000 or more. This product takes several applications over the course of a year to remove the rot but if you are willing to roll up your sleeves and spray your trees every few months, it definitely solves the problem. Trees are green now and no visible evidence of fungus remains. Amazon had by far and away the best pricing compared to other stores.

Best to apply in spring when new green leaves are first coming out. Re-apply in summer and if need be at end of summer before leaves begin to fall. It took care of a bad rusty fungus that was getting on everything! Must be vigilant to keep at bay, especially in the beginning. This product works great.

This has helped keep leaf spots and mildew at bay in my veggie patch. It’s easy to mix and apply, though I did have to unclog the nozzle once during a second application. Still a reliable choice for seasonal garden care.

This really helped with my tree in the backyard. The leaves looked very sickly, after doing research on what could be causing it I bought this fungicide. I sprayed it on as instructed and in just a few short days I could already see the overall improvement of the leaves. It worked fast and did exactly what I wanted it to do

This works well on everything but "rust"... Used twice and still have rust on cantalillies and plumeria, was happy that my chickens were not affected

For years (and I do mean YEARS) my maple had these black spots. Everything I read said that it was like "acne" and the tree would outgrow it. Come Spring 2025, she was not looking too hot. Losing new growth left and right. I purchased this hoping it was not too late. SAINTS ALIVE, this tree rebounded like new life was breathed into it. The leaves look amazing and recovered well into the summer. I did 2 treatments and thought its not as full as the other neighborhood trees. She is no longer losing leaves, the fungus is gone, and she provides adequate shade.

The copper fungicide is excellent for my trees, but the hose end container was not effective in delivering the chemical. Chemical solution is too thick to be delivered from the bottle. I checked with second bottle and it too didn't deliver the chemical.

This fungicide has saved two crape myrtles on my property! Something to keep in mind is that, depending on the power of your hose, the spray will probably only go 10-15 feet in the air. If you need to reach higher spots, you will need a powered or pressurized solution. You also need to make sure to shake the bottle every 30 seconds or so while you spray to ensure even distribution of the product in the spray. Also - make sure you protect yourself by wearing a mask while applying this above your head. I made the mistake of not wearing protection and completely lost my voice for three days.
