Abstract | ||||
Fungal diseases have a significant role in the low productivity of common bean crops. The use of fungicides is the most effective solution to control fungal pathogens, but excessive and indiscriminate fungicide use causes negative effects on the plant and the ecosystem. The quick advancement of nanotechnology seems to offer a novel solution to controlling phytopathogens. Different concentrations of three nanoparticles, Ag2O-NPs, CuO-NPs, and CaO-NPs were tested individually against Sclerotium rolfsii, the cause of root and crown rots. A significant effect was observed at 50 µg/mL. Our findings showed that the commercial fungicide Rizolex-T 50 WP and CaO-NPs did not perform as well as Ag2O-NPs and CuO-NPs in reducing disease incidence and severity caused by S. rolfsii. However, the three tested nanoparticles improved crop yield, defense enzymes (catalase, peroxidase, and polyphenol oxidase), and characteristics of plant development. | ||||
