Incidence rates of diseases in kiwiberry orchards were investigated monthly from late June to late September in Gwangyang and Boseong in 2015 and 2016. The impact of postharvest fruit rot was investigated during ripening after harvest. Bacterial canker was only observed on one single tree in 2015, but black rot, powdery mildew, leaf spot and blight, and postharvest fruit rot diseases were problematic throughout the study period in both 2015 and 2016. Incidence rates of the diseases varied with kiwiberry cultivar, region and sampling time. Incidence rates of powdery mildew, leaf spot and blight diseases increased significantly during the late growing stages near fruit harvest, while black rot peaked in late August. Incidence rate of postharvest fruit rot on fruit without fruit stalks was less than half of fruit with fruit stalks, regardless of kiwiberry cultivars. Among the four cultivars, Mansu was relatively resistant to black rot and postharvest fruit rot diseases. In our knowledge, this is the first report of various potential pathogens of kiwiberry in Korea.

2015年和2016年猕猴桃主要疾病的发病率。

从2015年和2016年的6月下旬至9月下旬，在光阳和宝城每月对猕猴桃果园的疾病发生率进行调查。对收获后果实腐烂在收获后成熟期间的影响进行了调查。在2015年和2016年的整个研究期间，细菌性溃疡病仅在一棵树上观察到，但黑腐病，白粉病，叶斑病和枯萎病以及收获后的水果腐烂病均存在问题。该病的发病率因猕猴桃品种而异，区域和采样时间。在接近水果收获的生育后期，白粉病，叶斑病和枯萎病的发病率显着增加，而黑腐病在8月下旬达到高峰。没有果梗的水果收获后果实腐烂的发生率小于有果梗的水果的一半，不论猕猴桃品种如何。在四个品种中，Mansu对黑腐病和收获后的水果腐烂病具有相对的抵抗力。就我们所知，这是韩国猕猴桃各种潜在病原体的首次报道。
