Curvularia Trifolii
''Curvularia trifolii'' is a plant pathogen. Host and symptoms ''Curvularia trifolii'' is a fungal pathogen which causes leaf blight in clover. When the host plant is infected, lesions on the leaf start to appear as yellow discolored patches. These patches will eventually turn brown and form characteristic V-shaped lesions in between the leaf veins. When the petiole is infected, the leaf withers and dies. Damage is more common in younger leaves of the clover plant. ''C. trifolii'' occurs severely when the temperature increases considerably after the rainy season. Environment ''Curvularia trifolii'' is commonly found in tropical regions around the world. Depending on the host plant, the pathogen can survive at temperatures of 40 degree Celsius with the optimal temperature range being from 25 - 30 degrees Celsius. This pathogen can be easily cultured in potato dextrose agar at room temperature (20 -25 degree Celsius). The color of the colony is white to pinkish-gray initially ...

Fungal Plant Pathogens And Diseases
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
