The objective of this study was to evaluated the in vitro fungitoxic activity against A. solani by homeopathic drug Ferrum sulphuricum in 32 dynamizations from 3CH to 99CH compared with controls treatments water-ethanol solution and distilled water. The results for mycelial growth rates of A. solani indicated that Ferrum sulphuricum 12, 21, 72, 75, 78, 81 and 96CH statistically different from controls, with values of 15% (75CH) to 38.5% (81CH) smaller than distilled water and 9.3 to 35% the hydroalcoholic solution 70%, respectively. For the inhibition of sporulation A. solani by Ferrum sulphuricum, it is observed that all potencies differed from the control distilled water except 57CH. The results indicate the potential of the drug Ferrum sulphuricum for alternative control of tomato diseases. (1729)
Ferrum sulphuricum at 6, 12 and 30CH ..... reduced the AUDPC [area under the disease progress curve] by 17% to 49%. Sulphur at 60CH and hydroalcoholic solution at 10% had a systemic effect on resistance induction (1765)
