ABSTRACT: Homeopathy has been present as a great resource with regard to plant
disease control as it not only represents less costs to farms, but also has shown great
results while reducing environmental impact. The aim of this study was to evaluate the
control of gray mold using homeopathic solutions of Sepia and Arsenicum in
dynamizations of 6, 12, 24, 36 and 48CH. As a control treatment were used water and
30% hydro-alcoholic solution (ethanol). It was evaluated the number of micro-sclerotia
and mycelial growth. The experimental design was randomized blocks with five
replications, and used the Tukey test at 5% probability, to compare the mean. For
mycelial growth, the better treatment was Sepia 6CH that reduced 34% the fungal
growth. In spite to the number of micro-sclerotia, just the control treatment with hydroalcoholic
solution was efficient, with a reduction of 73%.
