VERY potent and effective

Please use sparingly. Copper kills not only the fungus, but the plant as well. Follow the directions and you'll be fine.
This doesn't work instantaneously, so check the weather forecast and apply when it isn't going to be washed off by rain for at least 2-3 days. Also if you water manually avoid getting the affected/sprayed areas of the plant wet if possible. You should notice the fungus has stopped spreading/started dying in about 2-3 days. You might be tempted to reapply at this point but from experience I think it's better to wait a week as instructed and evaluate the results then.
If you want a product to use prophylactically against fungus, I can recommend the Neem Oil from this same company. The plants I treated with the Neem Oil BEFORE fungus appeared never developed fungal infections. Anyway I'll write a review on that if the opportunity presents itself.

keeps the fungus away! spray early morning or at night when there is little sun light or you will burn the leaves! does not take much at all. i used this on blueberries,blackberrys, cucumbers and more!

Seemed to WORK

Personally i think everything is extremely overpriced. That being said, I had what Google told me was fungus on my peach tree, and I sprayed this product on the leaves, which had turned orange and yellow, and it seemed to work.

Quick efficient garden/potted plant remedy

this item worked on the first application and I haven't had any issues since. The instructions were easy to follow and the plant I had the issues with cleared up after one application. I would definitely recommend this for any garden or potted plants that have the problems this product states it will handle.

Really works and fast!

I used this for a fungus on my Japanese maple and it was miraculous! I got new growth almost immediately. I'm going to continue to treat!
