摘要：
Blossom sprays with iprodione, chinomethionat, prochloraz manganese chloride, triadimenol, copper oxychloride, mancozeb, flusilazol, calcium polysulfide, and pyrazophos, applied fortnightly, were evaluated over two seasons (1989-1991) for the control of powdery mildew (Oidium mangiferae), blight (Nattrassia mangiferae), and blossom spot (Alternaria alternata and Colletotrichum gloeosporioides) of mango (Mangifera indica). Blossom sprays with the systemic fungicides flusilazol or pyrazophos resulted in significantly better disease control and consistently higher fruit set and yield than nontreated controls.
