Product Details:
BD 508 is used for preventive plant care when wet conditions favor fungal pressure. JPI directs fresh tea as a fine foliar mist and fermented tea as a soil spray. One 1.5-ounce dried-herb unit makes fresh tea for up to one acre or fermented concentrate that treats up to three acres after dilution.
Fresh Tea Instructions for BD 508 Bring one unit (1.5 ounces) of horsetail herb to a boil in one quart of water and simmer gently for one hour. Allow to cool. Strain and dilute by 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.
One-quart fermented concentrate option: Dilute the full quart with 2.25 gallons (9 quarts) of water, stir vigorously for 20 minutes, and apply as a soil spray to up to 0.75 acre.
