Zinc is a vital growth-driving micronutrient for crops. Zinc deficiency causes systematic growth disorders. Typical field symptoms include interveinal chlorosis on new leaves, small and brittle foliage, shortened internodes, clustered shoots, stunted growth, poor flower bud differentiation, low fruit set rate and increased deformed fruits. Fruits, vegetables, corn, rice and cotton are highly zinc-sensitive crops with widespread hidden yield loss caused by zinc deficiency.

Conventional zinc fertilizers show slow and unstable correction effects, often failing to relieve leaf yellowing effectively. EDTA-Zn features high activity and rapid absorption. It quickly participates in enzyme reactions and chlorophyll synthesis, obviously improving chlorosis, small leaves and stunted seedlings within 3–7 days and restoring normal crop growth.

Applied during flower bud differentiation, it greatly improves flower quality and fruit setting rate. Applied during fruit expansion, it accelerates nutrient translocation, reduces deformed fruits and fruit cracking, and promotes uniform fruit development with smooth skin and better appearance. It also enhances antiviral ability and delays leaf senescence, keeping crops vigorous throughout the growth cycle.

Whether for hidden soil zinc deficiency or visible leaf chlorosis, EDTA chelated zinc is the safest and most efficient correction solution.
