Boric acid crosslinked carboxymethyl cellulose hydrogels were synthesized to develop pH-triggered
release formulations (pH-TRFs) of boron and thiamethoxam. The developed hydrogels
showed pH sensitive water absorption capacity (16.75 to 110.80 g/g xerogel). Entrapment of
thiamethoxam was done through an ex-situ loading technique. The boron and thiamethoxam
release was studied in pH buffer solutions (4.0, 7.0 and 9.2). Release kinetics analysis using
mathematical models showed fast release in high pH solution as compared to acidic pH. These
pH-TRFs may find usefulness in selective release of nutrients and pesticides in plant rhizospheric
zone of problem soils viz. acidic soils and alkaline soils.
