Abstract: These compounds, represented by the formula (I) below, are used by way of agents inducing resistance to cryptogamic diseases in plants capable of being infested by a pathogenic fungus, for example, for the protection of wheat especially with respect to Septoria nodorum, Erysiphe graminis and Gaemannomyces graminis; of capsicum with respect to Phytophthora capsici; of melon with respect to Pseudoperonospora cubensis; of tomato with respect to Phytophthora infestans; and of "Xanthi" tobacco with respect to Phytophthora parasitica var. nicotianae.

Abstract: Plant wall-rich products originating, for example, from higher plants naturally rich in pectins, algae, or from by-products, such as wheat bran, potato pulp, shells or oil works residues, and the like, are modified to contain a fraction of water-soluble polysaccharides which is higher than, in particular equal to at least twice that existing naturally, without modification of their overall chemical composition. To obtain them, water is added, if necessary to the natural product in the divided state, to form a mixture capable of undergoing a shearing treatment, and the resulting product is subjected to a shearing force before extrusion, resulting in modified products as aggregates which can be converted into powder. By means of aqueous extraction, performed directly on the extruded product, a water-soluble fraction is obtained, from which there are isolated, for example, pectins, with a degree of methylation .gtoreq.
