One of the major issues facing the world today is the control of phytopathogenic fungus. One of the principal fungal diseases affecting agricultural foodstuffs in terms of crop production and monetary loss is the Fusarium genus. A novel technology with application potential in many industries, including agriculture, is nanotechnology. This study focused on determining potential effects of silver nanoparticles (AgNPs) compared with two traditional fungicides namely, thyophenate-methyl (Topsin-M^®) and ethylene-bis-dithio carbamate (Mancozeb^®) against phytopathogenic Fusarium oxysporum. AgNPs and Topsin-M^® both showed comparable outcomes for inhibiting mycelial growth, with corresponding percentages of 86.3% and 92.3%.This study demonstrated the promising effectiveness of AgNPs in controlling phytopathogenic fungi.
