ZMC™ Foliar Zinc, Manganese, Copper
- Zn is required for the formation of the critical plant hormone indole acetic acid.
- Zn is an essential component of several metallo-enzymes in plants and therefore is necessary to optimize many components of plant metabolism.
- Mn is critical in the oxidation-reduction process in photosynthesis.
- Manganese help control the activity of the plant hormone Indole Acetic Acid during vegetative and reproductive growth phases.
- Cu is essential in several plant enzyme systems involved in photosynthesis.
- Copper also aids in the formation of lignin found in cell walls, which help keep the plant upright and is important to seed set, stress resistance and pollen production.

Zinc controls the synthesis of indoleacetic acid, an important plant growth regulator that promotes cell division, directs the flow of food and other plant auxins. Zinc promotes growth hormones, starch formation and seed development/maturation. Terminal growth areas are affected first when zinc is deficient. Deficiency is most common in sandy and alkaline soils (high pH) or soils with low organic matter content that are high in available phosphorus.
Mn is essential in the “Hill” reaction of photosynthesis – the splitting of water to yield 4e- and O2
H20 + A + light -> O2 + H2A
Copper serves as an activator of numerous plant enzymes and plays a role in the development of plant pigments. Copper deficiency interferes with protein synthesis and has been observed on trees and vines growing on organic soils and sandy soils. Copper deficiency may be associated with high phosphorus, zinc or nitrogen levels. Foliar diseases are increased, and lignification is reduced or absent, with copper deficiency.
