ARMOUR-Zen® is a natural product specifically developed for the control of Botrytis cinerea in wine grapes and ornamentals and Sclerotinia sclerotiorum in ornamentals.
ARMOUR-Zen® contains a naturally abundant polysaccharide called chitosan. Different chitosan-based formulations will have different biological properties depending upon their source material and their manufacturing conditions, that is to say, not all chitosan’s are the same. Two different sources of chitosan were specifically selected for ARMOUR-Zen® because of their activity against Botrytis. ARMOUR-Zen® has been formulated as a water-soluble concentrate which is easily diluted for spray application.
A recent study in the scientific journal “Plant Pathology” shows that ARMOUR-Zen® is both anti-fungal and anti-microbial. It prevents spore germination and causes existing mycelia to shrivel and lose their structural integrity, halting the spread of the disease.
