Agrochemicals such as pesticides are used to protect crops and ensure food production. However, conventional formulations of agrochemicals contaminate the environment due to a lack of efficiency. Alternatively, polymers such as polysaccharides can be used to coat the active substance, thus decreasing its toxicity and delaying its release over several days. Moreover, when added to the soil, polysaccharides form hydrogels that improve soil structure, and store water and plant nutrients. The use of polysaccharides are reviewed by Campos et al.
