The interpolyelectrolyte complexes of poly(acrylic acid)‐chitosan were investigated as inductor of systemic resistance potentially useful in the organic production of vegetables. These complexes, which are water soluble, were tested in tomato ( Lycopersicon esculentum Mill. var. Floradade). The seed treatments were carried out using solutions consisting of 0.1 vol.‐% of the complex and 5 g · L −1 NaCl in water. The data showed that this treatment produced a higher resistance to the attack by Fusarium oxysporum and Phytophthora capsici pathogens in tomato seedlings.Formation of the interpolyelectrolyte complex of poly(acrylic acid) and chitosan.
