Bonide Copper Fungicide, 4 lb. Ready-to-Use Spray or Dust for Organic Gardening, Controls Common Diseases in Lawn & Garden

First time trying this in containers. Hope it works good. Thanks

I grow tomatoes in containers and have had issues with blight in the past. This product is easy to apply and effective in controlling the blight, and my tomato plants, being healthier, have produced a better yield. I will buy this again when I run low.

Leaf spot diseases (Septoria and early blight) are endemic to this area, and growing tomatoes turns into an epic battle every year starting in mid August. Left alone, plants won't survive past the start of September. I use a pump-up sprayer with about 8 heaping spoonfuls of this powder mixed into 1 gallon of warm tap water. It does not kill fungal disease, but arrests its spread until the next rain. Two mild showers or one big shower rinse it off completely, making reapplication necessary.In the fall, when misty/foggy weather happens overnight, the disease inevitably spreads, but copper fungicide will slow it enough that most of the plant is still healthy until frost.It does not really dissolve in high concentrations, so you must frequently shake/invert the sprayer to keep the compound in suspension.At fourteen bucks, this is by far the most economical way I've found to buy this stuff. Local retailers carry these ridiculously tall 1-pound jars for $8. For mixing with water, this is a lot easier to deal with.

good

Works on concord grapevine to control black rot, now if it would keep racoons away!

i expected it to at least go up to a ridge. nope half full. haven’t even tried it but i’m disappointed in it being only half full.

This stuff is great. We have some large indoor trees that contracted a fungus. Just two applications, the fungus was all dead.

works better than promised and doesn't bother pets
