This document presents sulfated polysaccharides derived from renewable non-terrestrial plants exhibiting exceptional antimicrobial properties and characteristics, and a method of manufacturing the same. Any of various species of red algae, brown algae, and brown seaweed (marine microalgae and/or macroalgae) are known to contain a high level of sulfated polysaccharides with inherent antimicrobial properties, and can be used in various implementations.

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.

Disclosed are compositions comprising chitosan, glucosamine and amino acids, where the concentration of chitosan is greater than 1.5 wt % and glucosamine is greater than 1.5 wt %. In preferred embodiments the concentration of chitosan is from 2 to 2.5 wt % and glucosamine is 2 to 6 wt %. The composition can also include solid chitin. The composition can also include trace elements, protein and other polysaccharides. The composition is generally a liquid but may be a solid. In most embodiments, the solid can be reconstituted with water prior to use. In preferred embodiments, the composition comprises HYTd and at least one of, HYTa, HYTb and HYTc. In other embodiments the composition comprises HYTd and two or more of, HYTa, HYTb and HYTc. The composition can also comprise HYTd, HYTa, HYTb and HYTc. In the disclosed processes soil, seed, seedling or plant foliage are contacted with HYTd or any of the above compositions.
