藏品描述：為臺灣夏季栽培時嚴重病害之一，病斑多由老葉開始，逐漸向上蔓延，出現褐色小斑點，以後擴大呈黑褐色，外圍有黃色暈環，後期產生小黑點。嚴重時造成葉片乾枯、落葉。
Leaf spots caused by Septoria are irregular, dark brown to black, sometimes surrounded by a narrow yellow halo. The spots are usually initiated on the lower leaves and the disease progresses upward on the plant. The leaf spots vary in size from very small to large, covering one-third of the leaf surface. The affected leaves turn yellow, die and persist on the plant.
