Although our product is not a phytosanitary product. In Lab test and field trials by Texas A&M, GroAloe help kill every bacteria, fungus, mold, virus, and yeast that they tried it on. We can not say that it will work on every type of pathogen because we have not tried it on every type of pathogen. So give GroAloe a try, it might be the answer that you have been looking for. Apart from it making plants healthier, greener that yield more. Forgot to mention that bugs do not like GroAloe. GroAloe is covered by IFOAM, OCIA, USDA, and OMRI as organic.
