ISTARKA is a special line of deficiency correctors for foliar application which are formulated with microelements, using lignosulphonates as chelating agents. Lignosulphonates are natural molecules derived from lignin which contain sugars that facilitate product penetration without phytotoxicity problems. They are recommendable for foliar application.
