Biogenic AgNPs—A Nano Weapon against Bacterial Canker of Tomato (BCT)

Figure 3

(a) Shows UV spectrum for the solution mixture of boiled fungal extract of P. oligandrum and AgNO₃ salt, showing no absorbance and hence no AgNPs production. (b) Represents untreated fungal extract exposed to AgNO₃ salt solution showing absorbance peak centered at 430 nm.
