Bonide Captain Jack Copper Fungicide 16 oz Concentrated Plant Disease Control Solution for Organic Gardening

I used the RTS version of this fungicide brand and found it very effective against powdery mildew. I'm giving this concentrate version a try to see if it's as effective as the RTS and save some money.

Worked quickly on my tomatoes. I applied after the stems were yellow and wilting. Those branches all died but the fungus stopped spreading. Plants are healthy now.

This product does work. We use it on our roses. A slight draw back is that you have to reapply often especially after it rains

Bought this for curl leaf on my peach trees. I will probably revisit this post and update it. Most likely next year but my cousin supposedly uses it says it works great so I'm giving it five stars

Useful for both early and late blight. Sprayed transplants immediately last year as soon as i saw signs of early tomato blight and saved them all. Sprayed monthly until end of season and avoided late blight entirely.

Purchased for my boxwood. Great product but!! The tape used to extra secure the cap is placed so that it covers the directions and then removes them when peeled off . There has to be a better way to apply it or different tape used.

Bought this for brown rot on my peach tree. I don't know if I bought the wrong stuff, or if this just doesn't work.I do know, it won't keep my peach tree healthy.

Will not mix with water
