EFFECT OF DIFFERENT FUNGICIDES ON RUST AND POWDERY MILDEW CONTROL IN COMMON BEAN, "CARIOCA" AND "GOIANO PRECOCE" CULTIVARS

SUMMARY The efficiency of Thyophanate Methyl, Chlorothalonil and (Thyophanate Methyl + Chlorothalonil on rust (Uromyces phaseoli) and powdery mildew (Eryaiphe polygoni) control was evaluated. A completely ramdomized block design was used with eight treatments and four replications. The fungicides spraying was done with an atomizer in base of 300 litres/ha on V4 (third leaf), R5 (pre-flowering) and R8 (full grown pods) growth stages. Yield and disease severity on leaves were evaluated. The fungicides spraying allowed an increase on the yield and a decrease on the severity of rust and powdery mildew.
