Phosgard® Copper is a nitrogen, copper, and slow release phosphorus fertilizer. Plants directly absorb the phosphite ions in Phosgard Copper and transport them from roots to leaves in the xylem, and leaves to roots in the phloem. Following proper application procedures, it should benefit plant growth, crop yield, and quality. Additionally, it improves plant health by inducing the immune response of plants. We developed it as a soil and/or foliar application, or as an application through irrigation water. The application rate is 32-48 oz./ac. (5-7 l/ha).
