摘要

Copper nanoparticles (CuNPs) and silver nanoparticles (AgNPs) were tested for their ability to inhibit the growth of Fusarium oxysporum f. sp. ciceris (FOC), causing Fusarium wilt disease (FWD) in chickpea. The results suggest that AgNPs at 0.1% and 0.01% had considerable antifungal action against FOC, with mycelial growth inhibited by 38.3% and 44.3%, respectively. Moreover, quantification and monitoring of these nanoparticles on a plant physiological parameter were addressed following the effects of the nanoparticles on chickpea seed radical development, and root and shoot biomass. The radical length of chickpea was increased to 10.52 cm and 10.17 cm with AgNPs and CuNPs, respectively, at a concentration of 0.1%. Root biomass was highest with 0.1% AgNP, while CuNP treatments showed no significant effect. All the nanoparticles were at par for the shoot biomass (p < 0.01). AgNP and CuNP at 0.01% showed the best results against FWD. This study highlights the potential of nanoparticles in managing chickpea FWD and suggests further research on root biology and pathogen interactions. Findings may guide the development of nanofungicides for effective FWD management in chickpea.
