Controlled release of herbicide into water from beta-naphtoxyacetic acid-layered double hydroxide nanohybrid formulation
At present, the use of huge quantities of herbicides in conventional agriculture has lead to some major environmental problems. Controlled release formulations (CRF) are now being developed to avoid such problems. The release of beta-naphtoxyacetic acid (BNOA) into aqueous solution from controlled-r...
