2.4.2. Antifungal Activity on Lemons

Three days after inoculation of *P. digitatum* P1PP0 in lemons (Figure 5), all tested concentrations of "Nitric-extract" significantly reduced rot severity compared to the control. Additionally, among these, "Nitric-extract" as such (ID02) and "Nitric-extract" at 75% (ID02) significantly reduced rot severity compared to all other control solution (treatments ID03, ID05, ID07 and ID09). "Nitric-extract" as such (ID02) and "Nitric-extract" 75% (ID04) were also the only treatments that, five days after inoculation, still maintained significant effectiveness in the reduction of rot severity in lemons (Figure 6).
