In India more than 60 % of the population relies on crops for their livelihood. However, crop diseases are one of the major factors limiting productivity. Hence, nanotechnology appears as a new means to control diseases and enhance yield. Here, stable copper nanoparticles were synthesized using cetyl trimethyl ammonium bromide and copper nitrate at room temperature, then characterized by UV–Visible spectrophotometry, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy and zeta potential measurement. The antifungal activity was evaluated against three common crop pathogenic Fusarium spp. We found that stable copper nanoparticles synthesized using 0.030 M cetyl trimethyl ammonium bromide and 0.003 M copper nitrate have the maximum activity against Fusarium equiseti with a 25 mm zone of inhibition, followed by F. oxysporum (20 mm) and F. culmorum (19 mm).KeywordsNanotechnologyAgricultureAntifungalCopper nanoparticlesFourier transform infrared spectroscopyTransmission electron microscopy
