No side effects to spray on mold with this fungicide. It takes several treatments to eliminate this mold.

I bought this product for a 10 year old healthy jade plant which had developed a little powdery mildew. (powdery mildew does not affect or kill plants) I called the company and spoke with there representative Scott who assured me this product would be OK to use on succulents (jade plant). I sprayed plant with premixed solution and was shocked to see the next day the plant was loosing all its leaves, just dropping and when I touched the plant the leaves just fell off, by end of day 85% of leaves were gone, frantic I called Scott again who denied that this should happen, I explained I was not a chemical scientist and could only translate what was happening to a beautiful healthy plant after using there product. This 2' thick leaf plant was given to me by my sister more then 10 years ago before she passed, so it meant a great deal to me. Not knowing what I could do to save this plant I gathered a lot of the fallen leaves bought succulent plant soil and tried to salvage leaves to propagate, within 2 days the replanted leaves turned black as well as the few remaining leaves on this beautiful healthy jade plane. I called Scott a final time who offered a free bottle of product, how nice, product killed a otherwise healthy plant and he offered to give me another bottle, that is a pretty odd offer. So be weary of using this product on succulents and hopefully you will not have my experience and heart ache of losing your plant!!!!

This stuff works very well! I had a potted mini rose plant with powdery mildew all over it! After spraying it a few times, it looks much better! ... It is a bit of a pain having to spray multiple times, but I guess if it was harsher, it could hurt the plant or the soil microbes. I'm glad I bought the concentrate, though, and not the ready-to-use bottles! ... It looks a bit like orange juice in the bottle and has a very slight orange scent (not a bad thing, just mentioning). Maybe that's because it contains citric acid. ... I like the fact that this is organic!

First time grower, I went all out with the bells and whistles. Tent, controllers, multiple fans, high end light setup etc. Though most of vegetation was completely fine, towards the end I ran into issues with powdery mildew showing up. After a LOT of research, it was a demon of my own making. Plants too close together, too many for the space, too high humidity, not enough airflow, I basically did all the wrong stuff. After discovering some SMALL spots on my leaves I panicked, researched, and resolved the environmental issues. It's now at proper humidity and temperature with adequate airflow and a carbon filter. Since doing that alone won't kill mildew, I started looking into options to "stop the spread". I tried the home remedies with neem oil, dish soap, milk, it just seemed to come right back. I decided to look for something a bit more focused for my issue and came across this organic solution. It works extremely well. If you follow the directions, it is very self explanatory. It's great as a preventative too, even if you don't have the powdery mildew issue currently. I bought the handheld spray version first as a tester, great way to lead into it. It worked so well I got the concentrate to use continuously, I use the original spray bottle and refill it. It works out to 1.8tsp of concentrate to refill that original spray bottle, so it will last a really REALLY long time for the home user at that rate. Overall, it will now be part of my standard arsenal for indoor growing.When i started seeing powdery mildew, my tent was at 80 degrees with 50-65% humidity when I started noticing issues, though it was that way due to multiple variables that have been resolved. Keep in mind, this product works great but is not a super cure. You MUST resolve environmental issues to keep it from coming right back, this just kills it on the spot
