5.0 out of 5 stars Excellent!

We were very pleased with the Growers Trust Powdery Mildew Killer. When we moved, we wanted to be sure we didn't inherit any powdery mildew in our yard. We used in in the early spring as a pre-emergent, on ALL the gardens and susceptible plants, then again when the new growth begins to appear. We end the season with an overall spraying for the winter. It works better than any other, it is biodegradable, natural, and being available in the variety of sizes (concentrate and strait) is a real plus.

This is not a good product. It does not kill or prevent white powdery mold. It did cause major leaf burn when applied as directed in the instructions. Do not waste your money on this product, find something else. Or just mix milk with water at a ratio of 1 part milk to 9 parts water.

It works but I think peroxide and water works just as good without the smell.

Received a spray bottle that's mostly empty; looks like it contains about 8 oz of liquid. Does not look like it can fit 32 oz. No dilution instructions that I can find.

Save your money and avoid purchasing this product. Simply put, it does NOT work. I actively applied this onto the leaves as directed and the powdery mildew still killed the pumpkins. Try other remedies and means to address powdery mildew as this one is a waste of both time and money.
