Earth’s Ally Disease Control Concentrate is a new generation of disease control formulated from food-grade citric acid. The formula effectively controls powdery mildew, downy mildew, blight, canker, black spot and leaf spot while leaving no harmful residue on plants. Earth’s Ally can be safely sprayed on herbs and vegetables up until the day of harvest. This concentrated formula yields 10 gallons of product, or approximately 50 spray bottles, when mixed with water.
For best results, shake the bottle, dilute 6 tablespoons concentrate in 1 gallon water and fully saturate the stems and leaves of the plant you are treating. Continue application every 5-7 days until the disease is controlled.
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.
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.
Used this today to battle the mildew we always get on our rose bushes. We caught the mildew early so very hopeful that Earth’s Ally will prevent the abundance this year. The spray bottle is top quality and applies a really nice coating on the leaves. The primary ingredient is Citric Acid so I’m confident it will be safe for vegetables when I need it.
It is an easy to use spray nozzle and the product smells like citrus. It’s not an overwhelming smell. I ended up using the entire bottle on my tree and it looks good. There a few leaves that are affected but the spray has kept most of the disease away. I wouldn’t reccomend the spray for a plant that is heavily diseased. I would say this would be good for maintenance.
I’m not a botanist! I don’t know black rot from rust, but Earth’s Ally makes it easier. I am seeing some improvement in my plants but I am finding it is necessary to do some repeated sprayings. I do not have definitive results yet but I will report back! I love that the product can be used up to the day of harvest. I am in the middle of tomato harvest and it is great I can keep my struggling plants in shape.
