Vigor 53®, a 25% potassium-buffered phosphorous acid in a completely enclosed micro-infusion system, provides potassium nutrition in addition to phosphite technology. This combination product works well in a total plant health care program that emphasizes natural plant health defense systems. The additional potassium aids in leaf thickening, better stem and root development, and stimulated frost or cold damage recovery. University research has extensively demonstrated the ability of potassium to aid in the recovery of leaf and stem diseases, as well as other stress agents involved in drought avoidance.
