Diagnostic Notes **Disease** Eyespot and seedling blight of sugarcane. Longitudinal leaf spots up to 12 × 6 mm, reddish with pale halo, coalescing. Chlorotic streaks may later run from spot towards leaf tip. Lesions can also form on stalks, and fungus may cause a seedling blight, especially under cool conditions. **Morphology** _Conidiophores_ arising singly or in small groups, often from a dark brown to black loose stroma, mid to dark brown, up to 200 µm long, 5–8 µm thick, with one or more distinct conidial scars. _Conidia_ single, straight or slightly curved, cylindrical or narrowly ellipsoidal, 35–95 µm long, 9–17 µm wide, pale to golden brown, smooth, 5–9-distoseptate (mostly 8), distinct basal scar 3–4.5 µm wide. 2.6.

  • Identification of New Fungi Isolated from Echinochloa Spp., As Potential Biological Control Agents in Paddy Fields in Iran
    Scientific Research and Essays Vol. 6(3), pp. 567-574, 4 February, 2011 Available online at http://www.academicjournals.org/SRE DOI: 10.5897/SRE10.813 ISSN 1992-2248 ©2011 Academic Journals Full Length Research Paper Identification of new fungi isolated from Echinochloa spp., as potential biological control agents in paddy fields in Iran Mohammad Reza Safari Motlagh Department of Plant Pathology, Faculty of Agriculture, Islamic Azad University, Rasht Branch, Rasht, Iran. E-mail: [email protected]. Accepted 24 November, 2010 Echinochloa spp . are the most important weeds of rice. Fungal pathogens can be exploited as biological agents for the management of agricultural weeds. Two pathogenic fungal species were isolated from naturally infected Echinochloa species and identified. In order to isolate the fungus from disease tissues, the obtained samples were cultured on potato dextrose agar medium. Isolates were cultured due to sporulation on water agar medium. Morphological characters of isolates were studied in order to identify the taxonomy. According to the results, isolates belonged to Bipolaris maydis (Nisikado and Miyake) Shoem., and Bipolaris australiensis (Tsuda and Ueyama) Alcorn. Pathogenicity test of isolates in species was done in desiccators, and revealed the pathogenicity of the species and their ability to cause leaf blight on Echinochloa spp.. Inoculation was done using a spore suspension consisting of 10 5 spore/ml distilled water and 1%Tween-20 at the 2 to 3 leaf stage. Results indicated that the disease rating caused by B. maydis and B. australiensis in Echinochloa spp. was higher than that observed in the studied rice cultivar. Hence B. maydis and B.

  • Cochliobolus Heterostrophus
    May 20Pathogen of the month – May 2020 a b c 50 mm d Fig. (a) Germinating conidium with appressoria (red arrows); (b) formation of an extracellular matrix around the appressorium and early formation of subcuticular hyphae; (c) subcuticular hyphal growth from a stomate (red arrowheads) and; (d) hyphal growth within the leaf ,(1934) ,(1934) mesophyll layer. Maize leaf lesions infected with C. heterostrophus were hand cut and cleared overnight in glacial acetic acid: ethanol solution. They were rinsed in water and then treated with Calcofluor White stain in (a) or Lactophenol Blue solution in (b) ,(c) and (d). Images were acquired with an Olympus BX50 and a Nikon Eclipse Ti microscopes on the Bioimaging platform, La Trobe University. Common Name: Maydis leaf blight, southern leaf blotch Disease: Southern corn leaf blight (SCLB) or leaf spot; leaf blotch Classification: K: Fungi P: Ascomycota C: Dothideomycetes O: Pleosporales F: Pleosporaceae Cochliobolus heterostrophus (anamorph, Bipolaris maydis) is a necrotophic, hetrothallic fungus which infects the leaves of Drechsler maize. The species is subdivided into three races: race O, race T and race C. Race T is the most virulent to maize plants ) carrying the Texas cytoplasmic male sterile trait due to presence of approx. 1.2 Mb of DNA encoding genes for T-toxin production. Other members of the genus include the necrotrophic corn pathogen Cochliobolus carbonum, the oat pathogen, Cochliobolus victoriae, the rice pathogen, Cochliobolus miyabeanus, the sorghum pathogen, Bipolaris sorghicola, the sugarcane pathogen, Bipolaris sacchari, and the hemibiotrophic generalized cereal and grass pathogen, Cochliobolus sativus. All species mentioned above produce host selective toxins.

Lemongrass oil, Citronella oil and Palmarosa oil are the names of commercially important essential oils extracted from the genus. The diseased samples of Lemongrass and Citronella were collected from Nagarjun garden and Centre of Excellence, Dr. PDKV, Akola. The fungi associated with foliar fungal diseases of lemongrass and citronella were isolated and identified on the basis of published literature and morphological characters which resembled with Dresclera tetramera, Bipolaris sacchari, Nigrospora sphaerica and Alternaria alternata. Dresclera tetramera, Bipolaris sacchari, Nigrospora sphaerica and K e yw or ds Alternaria alternata were found pathogenic to lemongrass and citronella causing leaf spot/blight diseases. The pathogenicity exhibited typical symptoms of Dresclera tetramera, Dresclera tetramera, Bipolaris sacchari, Nigrospora sphaerica and Alternaria alternata after 12 to 20 days from Alternaria alternata, the date of inoculation respectively and revealed their pathogenic association with the test Nigrospora sphearica, Bipolaris host plants.

This crop which was originally grown in South Eastern Asia and the Pacific for the sole purpose of chewing is mainly used nowadays for the production of sugar, bio-fuels, medicine etc. In spite of its numerous uses, the production of sugarcane in Buea, South West region of Cameroon is hampered by many factors including the incidence of disease. It is possible that some varieties are no longer cultivated because of their susceptibility to fungal diseases.
