Ciri dan struktur

Silver scurf is a plant disease of potato, which is caused by the anamorphic ascomycete fungus, Helminthosporium solani. Potato tubers are the only known host of Helminthosporium solani. It is a highly specific pathogen which does not have a secondary host or alternate host. A common symptom of this disease is blemishing on the surface of the potato tubers. These blemishes are tan and/or gray due to a loss of pigment, and they are usually irregularly shaped. Also, a post-harvest symptom can be shrinkage and shriveling of the outer tissue of the potato due to water loss. Black spots can also be found on the surface of infected tubers, which are a sign of the disease. These are made up of conidia and conidiophores of the pathogenic fungus. There are a number of conditions that favor the spread and development of H. solani. Usually, the temperature range of 15 – 32 °C combined with high humidity increase conidial germination. In addition to this, there are many cultural practices which affect the conditions that favor disease spread and development. These practices include: the level of H. solani present on the seed, planting and harvesting dates, crop rotations and warehouse management. It has been demonstrated that later harvest dates increase the development of the disease. It has also been demonstrated that the disease was more severe when planting densities were higher. All of these factors combined have an effect of disease spread and development. The spores can still infect and cause disease in daughter tubers in the soil for about two years. The fungus is contained in the outer layers of the potato and cannot infect very deep into the tuber.

Habitat dan peran ekologis

One of alasan utama untuk meningkatnya pentingnya ekonomi perak adalah kurangnya tingkat resistensi tinggi dalam cultivar kentang. Interspecific crosses dengan liar Solanum species telah digunakan untuk meningkatkan resistensi terhadap penyakit pada jenis S. tuberosum. Genes from spesies liar yang mengandung tuber Solanum demissum, Solanum chacoense dan Solanum aculae, yang memiliki sporulasi rendah dari H. solani, telah dimasukkan ke dalam latar belakang beberapa cultivar Canadian potato. Palang-palang interspesifik dan pilihan lanjutan ini sedang disaring untuk ketahanan terhadap berbagai penyakit termasuk kerutan perak. Namun, hingga saat ini belum ada varietas Solanum tuberosum yang tahan terhadap kulit perak.

Helminthosporium solani is a fungal plant pathogen responsible for the plant disease known as silver scurf. Silver scurf is a blemish disease, meaning the effect it has on tubers is mostly cosmetic and affects "fresh market, processing and seed tuber potatoes." There are some reports of it affecting development, meaning growth and tuber yield. This is caused by light brown lesions, which in turn change the permeability of tuber skin and then it causes tuber shrinkage and water loss, which finally causes weight loss. The disease has become economically important because silver scurf affected potatoes for processing and direct consumption have been rejected by the industry. The disease cycle can be divided into two stages: field and storage.

Ekologi sumber

One of the major reasons for the increasing economic importance of silver scurf is the lack of high levels of resistance in potato cultivars. Interspecific crosses with wild Solanum species have been used to increase disease resistance in cultivars of S. tuberosum. Genes from the wild tuber-bearing species Solanum demissum, Solanum chacoense and Solanum aculae, which have low sporulation of H. solani, have been incorporated into the background of some Canadian potato cultivars. These interspecific crosses and advanced selections are being screened for resistance to different diseases including silver scurf. However, no silver scurf-resistant cultivars of Solanum tuberosum have, thus far, been identified.
