Abstract

The present study deals with the utilization of psyllium and acrylic acid based hydrogels, synthesized under the influence of γ-radiations, in sustained delivery of copper sulfate, used as a fungicide in agricultural fields. Swelling behavior of the synthesized hydrogel was investigated in distilled water as functions of time, temperature, and pH. It was found that the hydrogel showed maximum of 10,578 % swelling at 25 °C for 24 h. The hydrogel was then checked for its sustained fungicide release behavior. It was observed that the hydrogel has been found to follow Non-Fickian type mechanism for the fungicide release. The ‘n’ and ‘k’ have been found to be 0.71 and 7.61×10−3, respectively.
