A unique formulation of chelated micronutrients, enhanced alpha-keto acids, and humic acid designed for foliar application as a supplement to citrus fertilizer programs.
KeyPlex Citrus HG is a formulation of micronutrients most often found deficient in citrus, plus nitrogen for accelerated uptake. It contains alpha-keto acids, which may facilitate utilization of micronutrients, and increase resistance to environmental stress. It also contains humic acid, which may enhance soil micronutrient availability. KeyPlex Citrus HG is formulated for foliar application to prevent and correct micronutrient deficiencies when used as directed.
Add 4 fl. oz. (8 tablespoons) to one gallon of water and mix thoroughly. Spray leaves to the point of run-off. For proper nutritional maintenance this product should be applied every 4-6 weeks during the growing season. The first (dormant) application should be applied at the earliest blossom stage (pinhead size bud).
NOTES: #1. Spray with caution around concrete patios, walkways, and other stainable objects—may cause staining. #2. Relocate household citrus to an outside stain resistant area during application. Allow time to dry, and relocate back to original location. Spray with caution around concrete patios, walkways, and other stainable objects – may cause staining.
