Using the agar well diffusion method, the antifungal activity of the leaf extract and the biosynthesized AgNPs were evaluated against Macrophomina phaseolina and Fusarium oxysporum. Before use, the potato dextrose agar and petri dish were autoclaved. Then, 0.1 mL of pure fungal culture was evenly spread on nutrient agar plates using an L-rod. The wells on the agar plates were then formed by the well borer, and 20 μL of aqueous samples of leaf extract and AgNPs (1000 ppm) was added. Nystatin and distilled water were employed as the positive and negative controls, respectively. The plates were finally incubated at 37 °C for 48 h to obtain the results.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
