桃黑斑病在我国40年代调查桃的产后病害时发现过此病,但是对生长期的黑斑病,此后较少见报。随着桃种植面积的扩大,从80年代起,河北等地区又开始有局部暴发的情况出现。因其在发病初期具有红尖症状,常被误认为是好桃,但装箱后发展很快,变成黑斑并引起腐烂,因而对产量和品质有较大的影响,严重的桃园减收50%~60%,损失惨重。 Peach Blot found in the peach peach disease in China in the 1940s found the disease, but the growing black spot, then less reported. With the expansion of peach planting area, some outbreaks have started to emerge in areas such as Hebei since the 1980s. It is often mistaken for a good peach because of its red-pointed symptoms at the early stage of its onset. However, it rapidly develops after packing and turns into dark spots and causes decay, thus having a greater impact on yield and quality. The serious decrease in Taoyuan 50% ~ 60%, heavy losses.
