Potato late blight in Myanmar
Maung Maung Myint ( Department of Plant Pathology, Yezin Agricultural University, Yezin, Myanmar)
Late blight is one of the most destructive diseases of potato in Myanmar. Potato late blight appears annually during July to September in Shan State highlands where rainy crop is widely cultivated. In this area, 40%～50% foliar blight is found yearly causing 21%～46 % loss in yield. Since late blight resistant potato cultivar has not been available in Myanmar, fungicides are used to control the disease on rainy crop. Potato growers, however, rely on early sowing to escape the disease because of high cost of fungicide application. They also used to store seed tubers properly, discard infected tubers and plant disease free ones with wide spacing.
