Efficacia di fungicidi contro tracheofusariosi e marciumi

In a temperature controlled glasshouse, seeds of tomato varieties not resistant to tracheo-fusarium diseases and rots were sown in soil inoculated with 3 strains of Fusarium oxysporum, F. solani, Pythium aphanidermatum, Pyrenochaeta lycopersici and Phytophthora nicotianae. In a 2nd experiment, seedlings were transplanted into similarly inoculated soil. Immediately after sowing/transplanting propamocarb 530 g/L +or- fosetyl 310 g/L at 4 or 3 mL/L was applied evenly to the soil surface. Damage from all the fungi except F. oxysporum f. sp. radici was insignificant in the sown tomatoes treated with propamocarb + fosetyl, while in the transplanted tomatoes, this treatment was effective except against F. solani and P. lycopersici.
