The value of EDTA-Cu goes beyond basic nutrient supplementation. It comprehensively optimizes crop physiological metabolism to boost growth and quality through improved root absorption, photosynthesis, plant toughness and fruit appearance. Stable active copper ions activate enzyme activity and accelerate the synthesis of carbohydrates and proteins, improving nutrient conversion efficiency and overall plant vigor.

During vegetative growth, EDTA-Cu promotes neat and thick green new leaves, preventing typical copper deficiency symptoms such as leaf chlorosis, tip whitening, leaf deformation and stunted growth. It strengthens root activity and nutrient transportation, eliminating weak and stunted seedlings and laying a solid foundation for high yield.

During reproductive growth, chelated copper balances nutrient distribution, improves flower bud quality and reduces flower drop and poor fruit setting. At the fruit expansion stage, it promotes uniform fruit growth, enhances peel toughness, improves color uniformity and glossiness, and reduces deformed fruits, effectively upgrading commercial fruit grade and market value.

Long-term standardized application of EDTA-Cu results in compact plant shape, robust stems and leaves, stronger stress resistance, fewer diseases, better appearance and stable high yield.
