Istarka Zn

ISTARKA Zn prevents or corrects zinc deficiency, by foliar application. Zinc is a micronutrient that is necessary for the production of chlorophyll and for the formation of carbohydrates. It is also a structural component of proteins and reinforces enzyme systems. Zinc deficiency provokes growth retardation, shortened internodes, spots and malformations in the leaves, and other physiopathies, reducing crop profitability.

The zinc content of ISTARKA Zn is complexed by lignosulphonates, natural molecules derived from lignin, containing sugars that facilitate the product’s penetration into the plant without causing phytotoxicity.

Micronutrients that are complexed by lignosulphonates are highly stable against photodegradation, and so ISTARKA Zn can be applied by foliar application while maintaining full effectiveness.
