This formulation of silicon and potassium phosphite is a unique duel action plant nutrient that improves tree health and resilience. Manufactured using Orion's unique and advanced iNHiB technology, Silvanus delivers stable, bioactive, monosilicic acid to the target plant. This form of silicon has been shown to enhances growth, strengthen cell wall and mitigate stress, thereby boosting the trees first line of defence against pest and disease attack. Phosphites are mobile and can be transported through the xylem and phloem to all areas of the plant. Once absorbed they stimulate and enhance the activity of the trees own defence system.
