Abstract: The field of nanotechnology opens up novel potential applications for agriculture. Nanotechnology applications are already being explored and used in medicine and pharmacology, however interest for use in crop protection is just starting. The development of nanodevices as smart delivery systems to target specific sites and nanocarriers for controlled herbicide release. Some nanotechnologies can improve existing crop management techniques in the short to medium term. Nanocapsules would help to avoid phytotoxicity on the crop by using systemic herbicides against parasitic weeds. Nanoencapsulation can also improve herbicide application, providing better penetration through cuticles and tissues and allowing slow and constant release of the active substances. Nanomaterials offer a wider specific surface area to fertilizers and pesticides. In addition, nanomaterials as unique carriers of agrochemicals facilitate the site-targeted controlled delivery of herbicide with season long control. Due to their direct and intended applications in the precise management and control of inputs (fertilizers, pesticides, herbicides) support the development of high-tech agricultural farms. In this review, we summarize recent attempts at innovative uses of nanotechnologies in agriculture that may help to prevent weed growth without hampering environment.
