Preparation 501

Preparation 501 is made from very finely ground quartz crystal silica, which is buried inside a cow horn over summer. The preparation was recently lifted from the ground on the 18th April 2017.

We apply 501 as a field spray within the vineyard.  The spray acts as a fungal suppressant by reducing humidity and increasing the thickness and toughness of the leaves and skins on fruit so they are less penetrable by fungal hyphae. 501 also increases sunlight photosynthesis with its reflective capabilities.  We this spray around the full moon when water influence is stronger with tide analogy, so we can counteract it.
