ABSTRACT
Introduction: The target spot is a disease caused by fungus Corynespora cassiicola (Berk. & Curt.) Wei. This
disease has occurred in several states of Brazil. It is a late season disease and causes economic losses in
various crops such as soybeans [1]. Currently there is no adequate treatment for the control of C. cassiicola in
organic cultivation of soybeans, since the application of fungicides for the control and management of diseases
is not allowed by Brazilian legislation [2]. Thus, the purpose of this experiment was to test the effectiveness of
high dilutions of Belladonna in vitro on mycelial growth of Corynespora cassiicola.
