The date of the beginning to spray the fungicides was the most important key. The various initial date would lead a different result even if the same fungicide was used, such as carbendazol, spraying fungicides from budburst or flower budding period to control the desease was the best. Ⅲ. B₂₅ and A₃₂ selected by us were the better to control the apple mold core in the fields. Biological control was worth to continue to test.
