Sweet Potato
Globalization has resulted in various problems because of increasing traffic around the world, now the risk of finding diseases that did not exist in Japan has also increased in the plant world. For example, it was reported that sweet potato root rot, which has not been confirmed in Japan, occurred for the first time in 2018 in sweet potato, which is Japan’s a major fall delicacy.
Sweet potato root rot is a plant disease that rots sweet potatoes during cultivation and storage, causing serious damage to the production of sweet potatoes. In addition, plant diseases with confusing symptoms often occur at the same time in the agricultural field, so there is a need for technology that can easily and quickly diagnose sweet potato rot.
