Bonide Copper Fungicide, 1 lb. Ready-to-Use Spray or Dust for Organic Gardening, Controls Common Diseases in Lawn & Garden

Will use for peach and nectarine trees for curl problem.

Works great

Very little dust for price but if you need it you need it

I like the powder more than the liquid form. Seems to stay in the vicinity of the plant longer.

I purchase this bran every year for our flower gardens. Works great

The copper dust works well on some but not all of my plants, I put the dust on my century plant cactus and it stopped the spread of black spot and rot, I did not think that anything could help black spot on cactus so I was very pleased with my results, I let the dust settle on each arm base and packed the root, I cut out the bad spots and made sure that the cactus was not getting too much water, 2 weeks later my cactus was healthy, the dust works well on my Cherry Carolina trees, the lantana plants and my Lilacs, be careful on other types of green leaf plants, the only bad thing about the dust is that it does separate and you have to get shaking it, I use a spoon and shake it well when I use it in the liquid form, I don't think that the dust will spray well, you have to be careful becasue some plants leaves may get damaged, over all I may please, good value for the money, will buy again.

Ok, I rarely both to go back and leave reviews but wanted to show my results for anyone who was having the trouble I was with copper deficiencies in two of my philos. I had these small yellow dots in both my jungle boogie and one of my rare selloums. Once I made the spray I sprayed each new leaf right after they unfurled and to my surprise, this actually worked. The new leaves didn't develop the yellow spots like the old leaves. So this won't affect the old leaves obv but can't believe it actually fixed the prob. Had a helluva time even figuring out what these spots even were. SO if this looks like your plant prob, I hope this will work for you too. It's an insane amount of powder that I'll never use all of since you dilute it so much, but so far the only thing that has worked for this prob. Good luck!

I can't tell if this works or not. I spray but it does not seem to stop the blight. There is no cure only prevention.
