Preparation of alginate–chitosan floating granules loaded with 2‐methyl‐4‐chlorophenoxy acetic acid (<scp>MCPA</scp>) and their bioactivity on water hyacinth

Abstract

We successfully prepared highly effective MCPA-loaded floating granules, which compared with an MCPA solution, exerted greater control on water hyacinth. Concomitantly, these granules provide a solution to spray drift and ensure the safety of natural enemies of water hyacinth, which is of great significance in research on herbicide formulations.
