Istarka Ca

ISTARKA Ca prevents or corrects calcium deficiency, by foliar application. Calcium helps stabilise the cell walls, strengthening the tissues, controlling the permeability of cell membranes and playing a role in stress-detection mechanisms and in the activation of defenses. The application of ISTARKA Ca prevents physiopathies associated with calcium deficiency, such as leaf necrosis and fruit rot or cracking.

The calcium content of ISTARKA Ca 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 Ca can be applied by foliar application while maintaining full effectiveness.
