Grower's Ally Fungicide Concentrate for Plants, 32 Oz, Makes 20 Gallons

This product cured my large, long hedge of its powdery mold. Thought I may need to reorder to treat again but no, took care of it. Great product!

Sprayed this on a rose bush that was covered in black spots and not looking healthy at all. Now I see new growth, healthy growth.

This worked very well on my hydrangeas

Definitely slowed down my blight and saved some plants

Not sure how well it works but $15 per bottle barely covered 12 tomato plants

I live in the southeast U.S. where it's very humid most of the year, and powdery mildew is a constant battle. I'd tried milder DIY options (baking soda solutions) and that worked ok on some plants (like my bee balm, which the mildew seems to love) but wasn't as effective on my succulents (and not the most convenient to use, e.g. spray nozzles clogging after awhile). Decided to give this a try, and it has worked great at controlling powdery mildew on both outdoor & indoor plants. Even a single treatment (I always forget whatever short-term repeat it recommends in the directions) clears up most mildew. Some reviewers have commented about leaves falling off after using this on plants with powdery mildew-- but yeah, sounds like that's from the fungus. You're not going to restore leaf damage from powdery mildew, the goal is to prevent further damage/avoid it damaging so much foliage that it significantly harms the plant. My bee balm has had no leaf-loss issues with this. Likewise, my succulents will usually have a brown scar where the fungus was but keep those leaves (it'd make sense for a plant to drop leaves if you treated them with a pretty intense or widespread infection, as they'd no longer be much use to the plant). I also lightly spray my uninfected succulents, prophylactically (at the same dilution), and they've not suffered any ill effects from the fungicide. One caveat, I feel like a fungicide perhaps shouldn't... grow a bunch of mold? (Happened in both the spray bottle and the slightly larger bottle that I use to make the dilution, a week or two after mixing it up; both bottles had been closed in the meantime.) It may be that the fungicide is just targeted to fungi likely to affect plants rather than being a "nuke it all" approach (which would actually be a good thing IMO) or just balancing strength vs. safety for plants (and humans, other stuff in environment, etc.). Not taking off any stars as it still works well as applied to my plants right after diluting-- I'll just mix up smaller volumes at a time from now on, fresh each time I need to use it.

Nice product,earth friendly

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!!!!
