Nine treatments were evaluated: seven chemical compounds, a biological agent formulation, and an absolute control. The formulation DE 975 + Fenarimol was applied at the beginning of flower developrnent. Its efficiency was compared to a single application and 4 ten day interval applications of an standard product (Folicur 200 CE - 100ml/l00L of water. Theresults showed that the treatment - DE 975 + Fenarimol 50ml/150L of water, wasthe rnost efficient for the control of powdery mildew reaching 0% of infection in wholecycle of the culture.
