The aim of this work was to evaluate the activity in vitro of the ethanolic extracts of Senna alata (L.) Roxb. over Monosporascus cannonballus. The experimental design was entirely randomized with factorial scheme 3 x 7 + 1, being constituted by three parts of the plant (root, stalk and green bean) for six different concentrations (0.25; 0.50, 50, 75, 250,500 ppm) plus the control, with four repeatitons for treatment. The available variables were: rate of micelial growth (TCM), inhibition of the growth micelial (ICM) and area under the curve of the growth micelial (AACCM). The concentration of 500 ppm was the most efficient ,in the three available vegetal parts. The percentual of inhibition in the concentration was of 28.60%, 36.70% e 27.99% for stalk, root and green bean respectively. Before of the results, the extracts of S. alata display high control potential for Monosporascus cannonballus fungi.
