Arber’s Bio Protectant is formulated from a species of weed called knotweed. Knotweed is a powerful little plant and considered one of the most invasive species in the world. Lucky for us, we were able to pull out some of its redeeming qualities. Through a complex fermentation and extraction process we grab key compounds to create our formulation. Harvesting an invasive species to create one of the most powerful plant protectants on the market—that’s a formulation we dig.
Extract of Reynoutria Sachalinensis: 5%
Other Ingredients: 95%
