Symptoms include yellow to tan spots on the plant's leaves and stems. Yellow spore-producing structures called pustules are produced on the lower (abaxial) leaf surface, and these are the signs of the disease. Spots on the upper leaf-surface coalesce and turn to brown-to-black as the disease progresses. The infected leaves eventually become dry and prematurely fall.〔(【引用サイトリンク】url=http://cannanews.blogspot.com/2008/06/canna-rust.html )〕 == Control == When Canna rust first appears, the affected foliage should be removed and discarded, otherwise the fungi will propagate and destroy the whole plant. The affected foliage should not be composted, as that will simply spread the fungus further. Commercially, a liquid copper-based spray can be sprayed on the stems and both sides of the leaves to prevent fungal problems before they occur. Although used commercially, copper is not recommended for home use because of its toxicity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Canna rust」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
