Inhibitory potential assessment of silver nanoparticle on phytopathogenic spores and mycelial growth of Bipolaris sorokiniana and Alternaria brassicicola

Inhibitory potential of silver nanoparticle (AgNP) at concentrations of 10, 20, 50 and 100 ppm was assessed on two foliar phytopathogens viz. Bipolaris sorokiniana and Alternaria brassicicola. Antifungal activity of AgNP was found to be significant in reducing germinating spores as well as mycelial growth of both pathogens in an experiment under controlled condition. AgNP at a concentration of 20 ppm was found effective to inhibit spore germination in B. sorokiniana as well as A. brassicicola. AgNP at 100 ppm resulted in restricting maximum mycelial growth for both pathogens. Hence, the current work revealed to apply 20 ppm of AgNP if considering a greater reduction in germinating spores of B. sorokiniana and A. brassicicola. | Inhibitory potential assessment of silver nanoparticle on phytopathogenic spores and mycelial growth of Bipolaris sorokiniana and Alternaria brassicicola
