## Description

Fungicide for Plants Concentrate - Indoor Outdoor Plant Fungicide Treatment Control for Powdery Mildew, Alternaria Blight, Rot, Fungus - Trusted by Cultivators - 8 Oz, Makes 5 Gallons

## Features

- MAXIMIZE YIELDS – This outdoor and indoor plant fungicide kills and prevents common plant pathogens, including powdery mildew, alternaria blight root rot, crown rot, and stem rot. When unavailable, use Earth’s Ally Disease Control, which provides the same proven fungicide protection.
- ZERO POLLUTANTS – Formulated with food-grade citric-acid, our formula is FIFRA 25(b) exempt and OMRI Listed for use in organic gardening. This garden safe spray tests clean and contains no residual solvents, no synthetic pesticides and no heavy metals.
- KILLS AND PREVENTS POWDERY MILDEW – Our broad-spectrum citric acid fungicide is an effective natural disinfectant. It reduces bacterial growth yet is gentle on plant tissue. When this powdery mildew treatment is used preventatively, citric acid forms a protective barrier on the surface of the leaves to inhibit pathogen development.
- HARVEST SAME DAY – The residue-free fungicide can be safely applied through all stages of plant growth, from clones through the flowering cycle when many problems occur.
- RECOMMENDED BY CULTIVATORS – Used across indoor, outdoor, greenhouse, and hydroponic grow spaces. An eco-minded formula that’s bee-safe and suitable for homes with kids and pets.

## 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).

## Customer Reviews

### ⭐⭐⭐⭐⭐ Eliminates plant fungus on contact!
*by J***Z on July 9, 2025*

Why did you pick this product vs others?:Ease of use and quality of this product. It works on contact in eliminating fungus from plants and was completely harmless to the treated plants. Also has long-lasting protection. There has been no further regrowth of fungus on treated plants.

### ⭐⭐⭐⭐⭐ Getting rid of mildew
*by B***B on August 21, 2025*

Fungicide is working after several applications for powdery mildew on my plants.

### ⭐⭐⭐⭐ 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.
