Relative percentage inhibition of different concentrations of plant extract against the pathogenic strain of E. coli. A) Well diffusion method B) Disc diffusion method, Whereas, T1 = 5 mM, T2 = 10 mM, T3 = 15 mM, T4 = 20 mM concentrations of ZnO-NPs. Different letters signify significant variations at LSD (P = 0.05), n = 3 and ± indicates standard error between three replicates.
