This past week, The University of Cannabis Technology delivered a presentation at the 2019 ICR Conference on using a newly approved substance to combat powdery mildew on cannabis plants during the grow cycle. This product, Agrowlyte, by Danolyte Global, is a proprietary formulation and process for making hypochlorous acid which is fully compatible with living plants. Traditionally, all manufacturers of hypochlorous acid have used Sodium Chloride (table salt) as the reagent in the process. While this is effective at producing hypochlorous acid, the residual salt remaining after the solution has dried is not compatible with living plants.
The makers of Agrowlyte have developed a process for producing hypochlorous acid that uses only naturally occurring chloride salts which are not detrimental to the health of plants. The result is a solution that can be safely sprayed on living plants without any negative effect on the plant. This aspect makes Agrowlyte unique in the market and the only hypochlorous acid product suitable for use on living cannabis plants.
Hypochlorous acid, the active ingredient in Agrowlyte, was approved in January of 2019 for use on organic produce without needing a rinse. This is because hypochlorous acid is an inherently unstable substance that degrades back into the water and chloride salts it was made from upon drying. It leaves no dangerous residue behind whatsoever, which is why it was approved by the USDA without rinsing for use on organic produce.
This test was conducted by Dr Matt Wheatley Ph.D. of UCANNTECH in October of 2018. Later experiments, also designed by Dr. Wheatley, were also conducted to determine if hypochlorous acid had any impact on either the cannabinoids or terpenes in cannabis buds when applied directly.
Powdery Mildew Treatment
In our initial experiments, we tested Agrowlyte against a control group of plants that were sprayed with plain water.
Here is the control group before and after –
As you can see in the photos the application of plain water caused the powdery mildew to accelerate growth and spread on the leaves. Since PM thrives in moist environments this result was expected.
Here are the Agrowlyte plants both before and after –
When the plants were sprayed with the Agrowlyte solution 3 times, 48 hours apart, the PM was no longer present on the leaves. The leaves did contain pigment scars where the PM had penetrated the leaf, leaving white patches behind on the leaves, but no PM was visible after three treatments.
We also wanted to verify that Agrowlyte would not have any impact on either the cannabinoids or terpenes in the plant. This is something that could potentially affect the value, safety or efficacy of a crop so we felt it was vital to test. 8 samples were tested, 4 controls and 4 Agrowlyte test samples. All samples were taken from the same plant for comparison purposes. When the results came in they were put through statistical analysis by Dr. Matt Wheatley for results. The analysis showed no statistical significance between samples at all. In the test we ran, both cannabinoids and terpenes were not affected after a complete soaking in Agrowlyte and drying for a period of six days next to the control samples that were taken.
Complete details from this test, in the form of a white paper, will be posted here as soon as it is available.
In summation, our limited testing did show that Agrowlyte, with its’ proprietary formulation, was able to be applied directly to living cannabis plants safely while being very effective at eliminating powdery mildew from the surface of the plant. Our test eliminated PM from the plants surface in less than a week while having no negative effect on the health of the plant. Further tests showed that Agrowlyte had no effect on either cannabinoids or terpenes when freshly harvested buds were soaked in it and allowed to dry.
Without question, further tests are needed, but Agrowlyte appears to have great promise for our industry, based on our testing. With the recent USDA Organic (no-rinse) approval Agrowlyte may or may not be completely legal to use on your cannabis plants. Please check with your local regulators to find out. As a University, we will continue to study Agrowlyte and encourage others to do the same.
