Using it on grapes, too soon to be certain there. The grapes had black mold on them last year to the point they were useless. Other treatments proved ineffective. However, we have several small Japanese maples we transplanted from volunteers from an established maple. The leaves got brown on the edges and curled up. They are in the third year with little growth evident. The trees survived, but wouldn't grow bigger. Sprayed them two weeks ago and leaves now look great plus new growth is evident.

I noticed my zinnia flowers were getting a fuzzy looking mold on the leaves, and my tomato plants had spots on them. I ordered Captain Jack, after reading all the positive reviews and this fungicide did not disappoint. I sprayed all my plants after the sun went down and by morning a HUGE improvement! All the mold was gone except for under a few leaves that I missed, so I resprayed them the next evening and my garden is beautiful again. I haven't noticed how well it will do on the tomato plants since they are brown speckled spots, but I am feeling pretty confident that this fungicide probably stopped it in it's tracks. I am very impressed with the effectiveness of this product and will definitely buy again.UPDATE: So, at first I was very impressed with this item and wrote a 5 star review, but quickly noticed that the mold/mildew I was dealing with came back within days. I have been spraying my zinnias every other day now with this product, but just can not seem to get the mold/mildew to go completely away. I have thoroughly and carefully made sure to spray all the leaves both on top and under to try to get rid of the problem and it seems to go away briefly, about a day or two. I have used this product on the rest of my garden and everything else seems to be doing fine.

It works for some plants, but the over-spray killed a few of my plants, so be careful to make sure your plant can tolerate copper fungicides. A small amount of overspray killed a three-year-old bonsai tree and two one-year-old bonsai trees, so I would use extreme caution around sensitive plants and trees.
