Abstract : The effect of fungicidal sprays applied during flowering were evaluated for the simultaneous control of powdery mildew (Oidium mangiferae), blight (Dothiorella dominicana) and blossom spot (Alternaria alternata and Colletotrichum gloeosporioides [Glomerella cingulata]) of mango inflorescences. The control of mango blossom diseases resulted in increased fruit set and yield compared with untreated controls. The highest yields were obtained with fortnightly applications of flusilazole or pyrazophos, commencing at 20% flower. Both treatments controlled powdery mildew, blight and blossom spot significantly.
