Product Details:

BD 508 can be used for soil or foliar applications, especially when conditions are too wet. It helps discourage fungal disease. One unit of the dried herb makes 3 gallons of fresh tea, enough to treat one acre, or 10 gallons of fermented tea.

Fresh Tea Instructions for BD 508 Bring 1.5 ounces or 1 unit of horsetail herb to a boil in one quart of water. Allow cooling. Strain and dilute adding 2 gallons of water. Stir vigorously for 20 minutes. Apply using a fine mist spray to the foliar parts of targeted plants.

Fermented Tea Instructions for BD 508 Bring one unit or 1.5 ounces of horsetail herb to boil in one gallon of water and simmer for one hour. Let cool and transfer to a crock or other storage container with a loose-fitting lid. Store this in a cool place, e.g. basement, and allow to ferment for 10 to 14 days, until the fermented tea has a strong sulphuric aroma. Strain the remaining herb particles out, fill the tea in a glass jug, and store it in a cool dark place until ready to use. It can be stored for 6 or more months without losing effectiveness. To use, add 1/2 gallon of fermented tea to 4 1/2 gallons of water, stir vigorously for 20 minutes, and use to treat up to 1 1/2 acres. One unit of horsetail can thereby treat up to 3 acres with as powerful effect as can be achieved by the fresh tea recipe on only one acre. The ratio for diluting is one part fermented tea to 9 parts water.

The fermented BD 508 should be applied as a soil spray, whereas the fresh tea version is the form used as a foliar spray.
