The next step begins with the preparation of the fungal samples. Fungal culture is crushed and mixed with PDB (Potato Dextrose Broth). Then the mix passes through a 100 µm filter (to remove large aggregates) and  through a 40 µm filter. The caught hyphae are mixed with PDB for 24 to 48 hours until OD (600nm) 2.5 is obtained. The previously seeded leaves are taken from the plant using a scalpel and placed in boxes above wet absorbent paper (leaves are kept alive for a week). Above each leaf, 5µl of the fungal suspension is deposited (using beveled tips because it is too viscous). As control, we kept inoculated leaves without fungus and leaves with only fungus. Pictures are taken at different times. All the plants are destroyed by autoclaving.
