  1. I am a hobby hop grower. I use the hops in home brewing. Hops are susceptible to powdery mildew and downy mildew.

    I am trying to be as close to organic as possible in my hop yard, so having an effective, organic treatment for mildew in my hop yard is a good step toward that goal. I got this product so that I will be prepared.

    I am looking forward to using this in my hop yard next season and will add to the review (if I can) with any results.

  2. It works!! We have had so much rain and humidity this year that green mold is growing on our tree trunks. I've been trying to figure out a way to safely remove this mold and not create more damage to our trees. This product seems to be doing just that. After spraying this tree trunk, I do see a big change. I'm impressed and will continue spraying!!

  3. I know alot of people may buy this product for their gardens. I do not have a garden but I do have alot of green stuff growing on my tree and on stuff in my yard like my fence. I used this on my tree and it actually helps with the green build up. After seeing how well it worked on my tree I ended up trying it put on my fence. I usually have to use bleach or a harsh chemical to clean my fence and other yard stuff. I figured I would try this spray on my patio furniture and my fence. It actually worked really well. I'm sorry I can't help you out if you want this for a garden but I can tell you it works great at cleaning up my tree and everything else in the yard.

  4. It is too early to tell whether or not the spray works as intended. However, one BIG difference between it and other bug, pest, and disease control sprays is the smell. I've previously used a disease spray on roses that smelled so bad that we could not be near the sprayed plants for days which is annoying. This spray does not smell bad and I'm happy to use it nearby where we hang out on the deck.

  5. Earth's Ally is an excellent group of products. We only use "natural" pest control in our garden and like all the products in this line that we tried. We especially like this item because it helps control mildew which is a big prioblem in hot, humid weather. I tried it on our squash which was really suffering from powdery mildew and it worked great. I was very pleased. I wil use it on my roses, too because they're having some black spot issues. Overall a great product.

  6. I was glad to try this organic method of disease control. It worked great on the powdery mildew on my zucchini and cucumber, but did not work so well on other unknown diseases on my cantaloupe and watermelon. I prefer organic any time I can find something effective to avoid chemicals. This had much less of a smell than neem oil, but didn't have as good overall effect.
