1. This report is the results of a survey on the main diseases and their damage degrees of watermelon in Taiwan.
2. In order to understand the occurring conditions of main diseases of watermelon in this island, we divided it into three parts-Northern, Central and Southern Taiwan, and surveyed in these parts respectively.
We surveyed 27 watermelon orchards in Northern Taiwan (included Hsingchu Hsien and Miauli Hsien), 10 watermelon orchards in Central Taiwan (included Taichung Hsien) and 13 watermelon orchards in Southern Taiwan (included Pintung Hsien and Kaohsiung Hsien).
3. The surveyed watermelon orchards were selected by ramdom sampling methods. In each orchard, we selected 5 plots which were located in East, West, South, North and Central parts of the field. At each plot, we investigated 40 plants and in total of 200 plants were examined in every watermelon orchard.
The kinds of diseases, damage degree, infected percentage and the kinds of watermelon were taken in note in detail.
4. According to the results of this survey, we knew that there were 7 kinds of main diseases on watermelon, such as fusarium wilt, gummy stem blight, mosaic virus, anthracnose, black spot, powdery mildew and root knot in Northern and Central parts of Taiwan. And 8 kinds of main diseases, such as fusarium wilt, gummy stem blight, mosaic virus, anthracnose, black spot, powdery mildew, downy mildew and root knot were discovered in Southern part of Taiwan.
Among these kinds of main diseases which we have mentioned above, the fusarium wilt in Northern & Central Taiwan, and the mosaic virus (of spring crop) & the gummy stem blight (of autumn crop) in Southern Taiwan were the severest of all.
