The 50 mg/L H2O2 concentration produced a 0.4 log reduction after 5 h. Exposure to 100 mg/L H2O2 already showed a slight effect on spore concentration, with a 0.5 log reduction after 3 h and 0.6 log reduction by the end of the experiment. F. solani suspensions were reduced 1.3 logs by 500 mg/L H2O2 after 3 h and 1.5 logs by the end of the experiment. In no experiment was the detection limit of 2 CFU, corresponding to a 2.7 log reduction in fungal CFUs, reached
