Rice blast (rice fever)

Japanese: いもち病(稲熱病) - いもちびょう（英語表記）rice blast

A disease caused by the rice blast fungus parasitizing plants. It is the most common disease of rice, occurring on ears, leaves, and stems and causing great damage. Combating rice blast has been a major challenge for rice cultivation, especially in mountainous and northern regions. Reflecting this situation, it is the disease that has been most frequently and intensively studied in the field of plant pathology in Japan. The first record of this disease in Japan is said to be in 1679 (Enpo 7) in the "Eiroku Since Our Hospital Records Annual" (Koshakuin Yueisho), but the later entry in "Kouka Shunju" (around 1707) is widely known.

Japanese:

植物に，いもち病菌が寄生して起こる病気。イネに最も普通の病気で，穂，葉，茎などに発生して大害を与える。とくに山間，北部地域では，いもち病との闘いが稲作の大きな課題であった。この事情を反映して，日本植物病理学の分野では最も多く，また深く研究されてきた病害である。日本ではじめてこの病気が記録されたのは，1679年(延宝7)の《永禄以来当院記録年鑑》(広積院祐栄書)とされるが，その後の《耕稼春秋》(1707ころ)の記載が人口に膾炙（かいしや）している。
