A ZMF formulation containing nitrogen and enhanced alpha keto acids for use on citrus and other tree crops and corn.

KeyPlex 445 DP is a formulation of micronutrients most often found deficient in citrus trees, other fruit trees, nut trees and corn. 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 445 DP is formulated for foliar application or fertigation to prevent and correct micronutrient deficiencies when used as directed. Maintaining proper levels of micronutrients usually results in increased plant vigor, better yields, superior fruit size and quality, and longer shelf life.
COMPATIBILITY
KeyPlex 445 DP, when added to the spray tank water, will lower the water pH, and can be used in combination with pesticides. However, in unfamiliar mixtures use a “jar compatibility” test.
DIRECTIONS FOR USE
FOLIAR APPLICATION: Mature Trees: Use 2 to 3 quarts of KeyPlex 445 DP per acre in a minimum of 50 gallons of water with ground spray equipment. Recommended application 2 gallons per acre per year. Addition of 3 to 5 pounds of urea or potassium nitrate per 100 gallons of water will aid leaf assimilation. Immature Trees: Use 2 quarts of KeyPlex 445 DP per 100 gallons of water and thoroughly wet leaf surfaces. Addition of 3 to 5 pounds of urea or potassium nitrate per 100 gallons of water will aid leaf assimilation. Corn: Use 1 to 2 quarts of KeyPlex 445 DP per acre in a minimum of 50 gallons of water with ground spray equipment. Addition of 3 to 5 pounds of urea or potassium nitrate per 100 gallons of water will aid leaf assimilation.

AERIAL APPLICATION: Use 2 quarts of KeyPlex 445 DP in a minimum of 15 gallons of water per acre.
