  • Works for white mold!
Size: 1 qt Style: Copper Fungicide
My poor little money tree I was growing started having a thick cover of white mold due to poor filtration. I wasn't sure what to do since I'm new to plants and everything, so after some research I knew I needed to buy some treatment. After looking around Amazon, I found this product and decided to take the risk.... and I'm glad I did! I sprayed my little fella with this every week and after a month of the treatment my money tree is doing amazing. I never write reviews, but I was surprised to see the white mold actually go away. It takes a lot of time and patience, but it's definitely worth it. It's not smelly at all which is a huge plus too. I'm very satisfied. ... show more

  • Immediate Impact
Size: 1 qt Style: Copper Fungicide
First year with roses, I knew they would have some special needs but wow have they been a chore! I have no idea what kind these are, the package I purchased looked NOTHING like these now that they have grown, it’s okay they must have been meant to be here! I had some black spot from my lazy watering. I cleared away the debris and removed any overly affected parts of the plant very gently. Watered properly and sprayed this on, the next day I have new buds coming on. Looking forward to having more and healthier flowers. I did not notice any smell from this product and no negative impact after getting it in my hands, just washed with soap and water. I chose this because it will not harm my beautiful pollinators! ... show more

  • Helped my hydrangeas in hot humid southeast weather
Size: 1 qt Style: Copper Fungicide
I tried several other fungicides and this is the only one that made a difference on my hydrangeas that were getting brown spot from the humidity. Other fungicides killed my hydrangeas making the leaves fall off. I will say though, you must be patient. The fix is not over night but it did reverse my brown spot over a period of using this product for a few months. I’m going to ensure I start using it earlier next year to prevent brown spot from even forming because it’s inevitable with this weather. ... show more

  • Excellent product
Size: 1 qt Style: Copper Fungicide
This product performed exactly as advertised. I used it to kill powdery mildew on my crepe myrtle tree, which got covered with the desease in a matter of days. I applied the product as directed, and my tree was free of this nasty mildew just as quickly as it arrived ... completely gone in just a few days. I only had to spray it with the product 3 times. If you're looking for solution for powdery mildew blight, I highly recommend this product. ... show more

  • Used This to Get Rid of Blight
Size: 1 qt Style: Copper Fungicide
Ugh! I had early blight on some of my tomato and pepper plants. Used this spray as per the directions and was able to save my plants that, happily, are now providing tomatoes and peppers for the family to enjoy.

  • Copper Fungicide Bond Captain Jacks Plant (bug/mold) spray
Size: 1 qt Style: Copper Fungicide
I purchased this Copper Fungicide spray to treat various succulents (including Jade plants) that had white mold & black spots. First, I cut off affected leaves, then copiously sprayed each plant, covering every portion, every 5 days for months. I continued to cut affected leaves & repeated the process until the mold/spots resolved. Some plants were nearly bald but the leaves have grown back & my plants are healthy. After months of treatments, I wiped each and every plant (leaves, branches, etc.) with alcohol pads to clean off any remaining debris, then rinsed each plant with water. This product saved my plants. It took a lot of time, patience and effort, but it worked. I highly recommend this fungicidal spray. You must be patient and willing to take time to save your plants. Good luck! ... show more

  • Works!
Size: 1 qt Style: Copper Fungicide
It took care of the mildew on my beloved phlox. I didn't even need to cut them back! So happy with this product. I'll be buying another couple of bottles next season.
