藏品描述:稻葉黑粉病,分布廣泛,是水稻生長後期的常見病。只為害葉片,病斑初起為褐色,沿葉脈呈斷續線條狀,後變黑色,稍隆起。嚴重時從葉尖開始逐漸枯死,且破裂成絲狀。
Leaf smut, caused by the fungus Entyloma oryzae, is a widely distributed, but somewhat minor, disease of rice. The fungus produces slightly raised, angular, black spots on both sides of the leaves. Although rare, it also can produce spots on leaf sheaths. Heavily infected leaves turn yellow, and the leaf tips die and turn gray.
