The aim of this research was to verify the action of sodium hypochlorite (NaOCl) in the control of Erysiphe diffusa in soybean plants applied alone or mixed to a fungicide. NaOCl was applied eight times during crop cycle in parcels that received the product in concentrations of 0,2; 0,4 and 0,6%, applied alone, and applied with fungicide, in only two applications. There was a control parcel and a fungicide parcel for comparison. It was not observed statistical differences among treatments in the comparison of the development of the disease in the parcels treated with NaOCl alone, fungicide and NaOCl mixed to a fungicide. It is suggested that more research should be done with NaOCl to evaluate its potential for fungus control.
