Appear II is a truly systemic fungicide. Phosphites are recognized for fungicidal activity to control Pythium spp. by blocking the development of mycelium. Phosphites are foliar and root absorbed allowing for translocation up through the xylem and down through the phloem of the plant, supporting complete plant protection. They are rapidly absorbed through both leaves and roots, with uptake happening quicker in warm weather. Phosphites accumulate in the plant but can be removed through mowing, thus the are recommended to be re-applied as part of a programmed approach.
