Comparative rate of rot-induction by nine fungal pathogens on stored tomato fruits in Nigeria

Characterization of Exserohilum rostratum, a new causal agent of banana leaf spot disease in China

“…Of the 18 susceptible plants, 10 including Caryota mitis, Chrysalidocarpus lutescens, Cynodon dactylon, Digitaria sangninalis, Eleusine indica, Gramineae poaceae, Miscanthus sinensis, Oryza sativa, Solanum lycopersicum and Zea mays, have been reported as natural hosts of E. rostratum. The remaining 8 plants (Archontophoenix alexandrae, Chrysopogon aciculatus, Cyperus rotundus, Dactyloctenium aegyptium, Panicum repens, Paspalum distichum, Roystonea regia and Setaria viridis) have been reported to be susceptible to E. rostratum by artificial inoculation (Chase 1982;Forsberg 1985;Leonard et al 1988;Okoli and Erinle 1990;Sun et al 1997;Chandramohan and Charudattan 2001;Cúndom et al 2006;Cardona and González 2007), demonstrating that the detached leaf inoculation method used in the present study could be considered as a rapid and effective way of investigating the host range of E. rostratum. The number of the newly discovered plants susceptible to E. rostratum made up 32.03% of the total number of plants tested (Table 4).…”

“…rostratum exists widely in nature and can survive as a saprophyte in soil (Liu et al 2008), elephant dung (Jeamjitt et al 2006), as an endophyte in plants (Sappapan et al 2008), and can cause diseases in many plants (Zummo 1986;Leonard et al 1988;Okoli and Erinle 1990;Luan et al 2004;Cardona and González 2007), animals (Contidíaz et al 2003) and humans (Saint-Jean et al 2007), revealing a considerably broad range of genetic diversity in its population. Intraspecific variation of E. rostratum was also confirmed in Brn1 gene sequences (Zhang and Sun 2005).…”

“…rostratum is a fungus with a broad ecological niche and shows considerable diversity in nature. The fungus causes disease symptoms on more than 30 plant species covering 28 genera in 11 families, including many economically important crops such as corn, rice, sugarcane, sweet sorghum, tomato and wheat (Zummo 1986;Leonard et al 1988;Okoli and Erinle 1990;Luan et al 2004;Cardona and González 2007). In some cases, E. rostratum is known to cause severe yield losses, for example, corn seed infection has been recorded at the rate of 85% and corn leaf incidence up to 18% (Leonard et al 1988;McGee 1988).…”

Effects of Storage Methods and Duration on the Microbial Composition and Load of Tomato (Solanum Lycopersicum [L.], Solanaceae) Fruits

“…Ghosh (2009) The effect of these microorganism has the potential of causing substantial market losses to both the farmers and traders of tomato fruits across the country. For example, a tomato fruit affected by Rhizopus stolonifer has caused the most rapid rot on stored tomato fruits in Nigeria as observed by Okoli and Erinle (1990). Fungal spoilage of tomatoes has been recognized as a source of potential health hazard to humans and animals because they produce mycotoxins, which are capable of causing mycotoxicoses in man following ingestion or inhalation (Baker, 2006).…”

Exserohilum rostratum causing sugarcane leaf spot in Iran

“…Exserohilum rostratum causes leaf spot on grasses (Sivanesan 1987) and is opportunistic, etiologic agent of sinusitis, which may extend to the central nervous system, and keratitis, as well as cutaneous and subcutaneous mycosis in human (Revankar and Sutton 2010). The fungus causes disease symptoms on more than 30 plant species covering 28 genera in 11 families, including many economically important crops such as corn, rice, sugarcane, sweet sorghum and tomato (Zummo 1986;Leonard et al 1988;Okoli and Erinle 1990;Cardona and González 2007).…”
