BTH处理对甜瓜品质、产量没有影响，降低了甜瓜果实病害，抑制了白粉病和细菌性角斑病的发展。

Disease of fruit and leaf of powdery mildew and bacterial spot were suppressed by BTH treatment during development stages of melon .

各处理均降低了甜瓜叶部白粉病病害指数。BTH处理的细菌性角斑病的发病指数比对照降低了0.95。

Index of bacterial spot of leaf treated BTH compared with CK reduced at 0.95 . Quality and yield of melon was not affected by BTH treatment .
