藏品描述：炭疽病是柑橘貯藏後期的主要病害之一，但為害比蒂腐病及綠黴病等輕微。病菌亦危害葉片及枝條，當葉片受傷，將近落葉或葉片活力減低時，自葉片先端或葉緣開始枯萎，或葉肉形成褐斑，產生炭疽病菌。染病果實貯藏期間，果皮出現茶褐色斑點或斑紋，不久呈淡紅色濕潤狀之腐爛。
A disease of various citrus plants (as orange, lemon, and grape fruit) caused by a fungus (Colletotrichum gloeosporioides) and characterized by twig blight of mature tips, leaf spots, and fruit stains, spots, or rots.
Anthracnose is a primary colonizer of injured and senescent Citrus tissue. The disease is especially troublesome on fruit that are harvested early and degreened for over 24 hours because ethylene stimulates the growth of the fungus. Symptoms on leaf are a more or less circular, flat area, light tan in color with a prominent purple margin that at a later phase of infection will show tiny dispersed black flecks.
