desertcart.com: Grower's Ally Fungicide Concentrate for Plants, 24 Ounces | Food-Grade Formula for Powdery Mildew, Mold - OMRI Listed & Safe for Harvest Day, Pets - Ready to Use Spray Indoor or Outdoor : Patio, Lawn & Garden

Review: Good for powdery mildew - 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.
Review: Works really well really quickly for powdery mildew - I had powdery mildew on my strawberries and this got rid of it super fast

## Features

- BROAD-SPECTRUM PLANT FUNGICIDE FOR GARDEN USE: Helps prevent and control powdery mildew, blight, leaf spot, black spot, and crown rot on houseplants, vegetables, and ornamentals. Food-grade citric acid formula works throughout the growing cycle. Safe for use on edible crops.
- COPPER-FREE ALTERNATIVE - Unlike copper fungicide that can burn tender growth, stain surfaces, and accumulate in soil over time, this citric acid formula provides effective fungal control without plant damage or environmental buildup. Gentle on new growth with no copper application limits.
- NO HEAVY METALS, SYNTHETICS OR NEEM: Active ingredient is food-grade citric acid, the same compound used in food production. FIFRA 25(b) Exempt and OMRI Listed for organic gardening. No chlorothalonil, no copper, no synthetic pesticides, no residual solvents. Won't harm bees, butterflies, or beneficial insects.
- INDOOR-SAFE APPLICATION: Mild citrus scent with low odor makes it suitable for indoor grow rooms, houseplants, and greenhouses. Safe to use around pets and children once dry. Ideal for enclosed spaces where strong-smelling products aren't practical.
- APPLY IN EARLY MORNING OR EVENING: Spray dry plants only. For indoor gardens, turn off lights and fans during application and for 2-3 hours after. For active outbreaks, apply once, wait 4 hours, reapply, then treat every 3-5 days. For prevention, spray every 7 days. Test on a small leaf area first for sensitive plant varieties.

## Questions & Answers

**Q: Effective and safe against grey mold on cannabis buds?**
A: Gray mold, or botrytis, is very difficult to treat.  Grower's Ally Fungicide can help slow the spread of gray mold, but will not cure the disease or repair infected plants / buds.  Infected buds need to be removed properly, and the environment (lower humidity, increased airflow...) must be addressed first, before any product can help you.  There are many excellent articles that go into great detail about effectively treating gray mold.  We wish you the best.

**Q: Will this help leaf spots on mountain laurel?**
A: If I can sure.

**Q: Will this work for peach curl?**
A: You must use a copper based fungicide that is specifically labeled for peach or nectarines

**Q: Does this work on pachysandra blight**
A: Grower's Ally Fungicide will work to help prevent the spread of blight on pachysandra, but it will not repair parts of the plant that are already damaged.  We strongly recommend removing diseased leaves and disposing of them properly (and disinfecting your pruning tools).

### ⭐⭐⭐⭐⭐ Works really well really quickly for powdery mildew
*by K***I on August 13, 2026*

### ⭐⭐⭐⭐ Effective garden staple
*by G***. on September 3, 2025*

This works pretty well, but like any of these sprays, it's much better proactively. Once things go bad, it's not a savior, but it should be a staple if your a grower. No harmful effects to the plant or the people spraying it. You can use a lot without any negative effects, and it is effective.
