Ciri dan struktur

Conidia is the primary and secondary inoculum of the plant. This asexual structure is produced from conidiophores on infected plant residue (Lin and Kelly, 2018). The conidia can also be moved over short distances by wind currents (Mian et al., 2008). The most suitable conditions for infection are warm and wet weather between 25 and 30 °C with greater than 90% humidity (2018). The fungus has more of a damaging impact when infection occurs before or at flowering (Lin and Kelly, 2018). Fungal infection occurs with direct contact from an already infected soybean pod but the fungus can also spread from seed to seed during plant growth. If infection does occur, external plant damage can be seen one to two weeks after contact with the pathogen. Cercospora sojina is a fungal pathogen that varies in colony color, growth rate, and spore formation in culture. The main infection structure of the pathogen is the conidia which is produced from light or dark conidiophores and rests on the tip of the structure. The conidia appear translucent and form cylindrical to round tapering shapes. The size varies between 6 micrometers to 40-70 micrometers and depends on how much area is available for growth (Lin and Kelly, 2018). More specifically, when comparing nonresistant and resistance strains of the pathogen from China, researchers observed 5 candidate genes that are linked to virulence. The gene's function was related to metabolic mechanisms and the production of metabolites that can cause reduction in host resistant soybean plants (Gu et al., 2020). Cercosporin is one non-specific colored mycotoxin produced in some Cercospora species.

Habitat dan peran ekologis

Kacang kedelai adalah tuan rumah utama patogen ini. When the patogen terjadi pada kedelai, itu menyebabkan lesi daun kecil. Lesi ini, sebagian besar ditemukan di permukaan daun atas, tidak teratur bulat dan terdiri dari batas berwarna merah-kecoklatan hingga ungu. Bagian dalam luka seringkali berwarna abu-abu sampai coklat. When the lesi matang, mereka kertas tipis dan daun yang terinfeksi tampak pecah dan lama. Penyakit ini dapat menyebabkan pelepasan rambut dini. Tanda Frogeye leaf juga bisa terbentuk pada batang dan batang dari spesies yang sangat rentan. Oval and lesi lingkaran yang terbentuk pada batang dan batang memiliki margin berwarna gelap dan warna abu-abu terang hingga coklat merah di bagian dalam. If the pod terinfeksi, benih juga bisa terinfeksi tapi mungkin tidak memiliki gejala. If they menunjukkan gejala, bintik-bintik abu-abu terbentuk pada benih dan lapisan benih retak sering terjadi. Tumbuhan ini paling rentan terhadap infeksi ketika daunnya muda dan berkembang atau jika daunnya tua dan tua. With this rentang rentan, penyakit dapat terjadi beberapa kali di seluruh kanopi tanaman jika lingkungan ideal untuk patogen pada setiap lapisan daun muncul. Hal ini menyebabkan bagian penyakit berlapis pada satu tanaman.

Ringkasan sumber

Cercospora sojina is a fungal plant pathogen which causes frogeye leaf spot of soybeans. Frog eye leaf spot is a major disease on soybeans in the southern U.S. and has recently started to expand into the northern U.S. where soybeans are grown. The disease is also found in other soybean production areas of the world.

Ekologi sumber

The soybean is the main host of this pathogen. When the pathogen occurs on soybeans, it causes small leaf lesions. These lesions, mostly found on upper leaf surfaces, are irregularly circular and consist of red-brown to purple colored borders. The inside of the lesion is often a gray to tan color. When the lesions mature, they are paper thin and the infected leaves appear tattered and weathered. The disease can lead to premature defoliation. The Frogeye leaf spot can also form on the pods and stems of highly susceptible cultivars. Oval and circular lesions that form on the pods and stems have dark-colored margins and light gray to reddish-brown color on the inside. If the pod becomes infected, the seeds can also become infected but may be symptomless. If they do show symptoms, gray blotches form on the seed and a cracked seed coat often occurs. The plant is most susceptible to an infection when the leaves are young and expanding or if the leaves are old and senescing. With this range of susceptibility, the disease can occur several times throughout the plant canopy if the environment is ideal for the pathogen at each leaf layer emergence. This leads to a layered section of disease on one plant.
