Abstract
在本省玉米銹病有兩種，即普通型 ( 由Puccinia sorghi 引起) 及南方型 ( 由 P. polysora 引起)，目前仍以南方型較為普遍。根據氣象及發病資料分析，春作玉米南方銹病的發生和發病 7 天前之溫度 24.1-28.0℃ 及 28.1-32.0℃ 相關最大，秋作玉米則和 8-14 天前之溫度 20.1-24.0℃，24.1-28.0℃ 及 28.1-32.0℃ 相關最大。
Two kinds of corn rust, common rust (Puccinia sorghi ) and southern corn rust ( P. polysora ) were found in Taiwan. However, southern rust is more common at present. By analyzing the meteorological factors and southern rust disease, it showed the the most important meteorological factors were temperature 24.1-28.0℃ and 28.1-32.0℃ seven days before disease occurrence during spring cropping season, and 20.1-24.0℃, 24.1-28.0℃, and 28.1-32.0℃ 8-14 days before disease occurrence during fall cropping season.
