Ciri dan struktur

Plants infected by chrysanthemum white rust exhibit spots on the upper surfaces of leaves. These spots are initially pale-green to yellow in color and up to 5mm in diameter, but may turn brown as the tissue becomes necrotic. On the underside of the leaf, stems, and flower, spots develop into pink or white waxy telial clusters/pustules where teliospores develop. Pustules are able to form on any green tissue of the plant, but are most common on young leaves and flower bracts. Puccinia horiana is a microcyclic, autoecious rust, meaning that the fungus has two known spore stages: teliospores and basidiospores, as well as no known alternate host. Similar to other microcyclic rusts, two-celled teliospores produce unicellular basidiospores which are then dispersed via air currents. Basidiospores are disseminated 3–6 hours after development through wind and/or water. Symptoms begin to occur 7–10 days after penetration into the epidermis. Shortly after leaf spots appear, telial clusters will begin to form on the stems, flowers, and abaxial leaf surfaces. This is where teliospores develop. These teliospores will produce basidiospores initiating a new cycle. (i) Basidospore lands on susceptible plant. Development of germ tube and infection peg begins. (iv) Formation of septate fungal vesicles with branching hyphae. Here the fungus will move to infect the rest of the plant. Maintain production area at less than preferred humidity for spore germination and survival Follow specific sanitation protocols for personnel Train personnel on symptoms and proper management practices Avoid over and under-story of known hosts Confirm that host stock comes from CWR free nursery Inspect plants as soon as they arrive Cuttings should be treated with fungicide before planting Separate mother stock from main production area

Habitat dan peran ekologis

Chrysanthemum white karat (CWR) pertama kali diidentifikasi di Japan in 1895. Jamur Puccinia horiana pertama kali dijelaskan dan diterbitkan oleh German mycologist Paul Christoph Hennings (1841–1908), ketika ditemukan di daun Chrysanthemum sinense di Honshu, Jepang. Sekarang sudah ada di seluruh Asia, Eropa, Australia, dan Amerika Selatan. Penyakit ini telah ditemukan di Amerika Serikat States on beberapa kali, tetapi upaya mendeteksi dan memberantasnya sejak dini telah mencegah penyakit ini menjadi mapan.

Ekologi sumber

Chrysanthemum white rust (CWR) was first identified in Japan in 1895. The fungus Puccinia horiana was first described and published by German mycologist Paul Christoph Hennings (1841–1908), when found on the leaves of Chrysanthemum sinense in Honshu, Japan. It is now established throughout Asia, Europe, Australia, and South America. It has been found in the United States on several occasions, but early detection and eradication efforts have prevented the disease from becoming established.
