Development of agar-alginate marine polysaccharides-based hydrogels for agricultural applications to reduce environmental hazards.

In order to meet global food requirement, innovation in agricultural techniques and pesticide delivery system will be required for sustainable food supply with minimal harmful impact on environment. This article discusses the synthesis of hydrogels for use in controlled release formulations (CRFs) to increase agricultural output while reducing ecotoxicity and health risks. These hydrogels were designed by graft-copolymerization reaction of polyacrylamide and polyvinyl sulfonic acid onto agar-alginate marine polysaccharides.
