Abstract: The present invention relates to a method for modulating plant processes said method being characterized in that a plant is fed with an eco-friendly, plant- and/or algae-derived, biostimulant composition comprising exogenous small RNA molecules. In particular, the method of the invention can be used for modulating physiological or pathological plant processes, such plant growth, plant productivity, fruit quality, quality of produce, plant yield, plant response to abiotic stress and plant resistance to diseases or to infections.

Abstract: The present invention relates to a process for the preparation of polyaminocarboxylic acids, in particular phenolic aryl- or alkyldiaminepolycarboxylic acids, preferably a compound of formula (I): wherein X is selected from the group consisting of: H, COOH, COO?Y+, OH, linear or branched C1-C5 alkyl, CH2OH, SO3H, SO3?Y+, wherein: —Y+ is independently selected from the group consisting of: Li+, Na+, K+, and NH4+; and wherein A is selected from: —A (CH2)n linear aliphatic system, wherein n=2, 3 or 4, preferably 2 or 3; and —an aromatic system of formula (II): wherein R1, R2 are independently selected from the group consisting of H, OH, and linear or branched C1-C5 alkyl; said process comprising the step of reacting, a phenol compound, glyoxylic acid and an aryl- or alkyldiamine in the presence of an iron source to obtain a reaction mixture comprising the compound of formula (I).

Abstract: The present invention relates to an agricultural composition and the uses thereof to protect crops against attack by plant pathogens and/or to improve the resistance of crops to infections caused by said pathogenic agents and/or to enhance the tolerance thereof to abiotic stresses, such as those caused by cold, salinity and drought. Said composition comprises an association of an at least partially depolymerized chitosan with a bivalent copper chelate. The composition has shown to be particularly suitable-for treating oidium infections. It is moreover useful against the propagation of viruses and/or particularly effective as a biostimulant to plant and fruit growth and/or able to extend the shelf life of fruit and seeds.
