Micrap Zinco 15 is a formulation based on zinc EDTA chelated, used in foliar applications in order to prevent and treat zinc deficiencies of plants, causing internodes shortening diseases as well as a proliferation of smaller, misshapen and weaker fruits. Zinc increases tryptophan production, an amino acid that is a precursor of the indoleacetic acid (IAA) synthesis, which plays a growth regulation role in plants. Zinc enters also many enzymatic processes that control carbohydrates metabolism, proteic and auxines biosynthesis, besides influencing the formation of cell membrane structure. Micrap Zinco 15 also improves yields’ quality and quantity.
