The intense use of pesticides contributed to the contamination of soils and groundwater. Nanopesticides (colloidal suspensions of nanocarriers loaded with pesticidal compouds) have been proposed to overcome technical and environmental problems of traditional agrochemicals.

Here a novel nanoformulation is presented, based on eco-compatible materials (mineral particles and food-grade biopolymers), and applied to dicamba, a highly soluble herbicide, to control its delivery and reduce environmental spreading.
