Corn is largely affected by this fungus, especially certain varieties that have been genetically engineered. These engineered varieties are more susceptible to the teleomorph phase of the fungus. The anamorphic phase, ''C. graminicola'', is typically latent and does not negatively affect the host plan t. It is not until the fungus moves to the teleomorph phase of the lifecycle and begins to produce fruiting bodies that host plants will begin to exhibit symptoms, often on plants depleted in energy after the stress of pollination. Once the pathogen is in a field, producers can suffer huge economic losses. The disease, corn anthracnose leaf blight, is the most common stalk disease in maize and occurs most frequently in reduced-till or no-till fields. As these practices are widespread, as can be the pathogen. == Host and Symptoms == ''C. graminicola'' is a fungal pathogen that colonizes and infects many turfgrass e.g., Bluegrass, Ryegrass, fescue''.'' In addition to the grasses, C''. graminicola'' also infects many grain crops such as barley, wheat, sorghum and corn. The fungus can infect many different parts of the corn plant, typically the kernels, tassels, roots, leaves, stalk and husks. The most common area of infection is the stalk. C. g''raminicola'' produces three major symptom types: leaf blight, stalk rot and top die-back. The leaf blight is characterized by round yellowing water soaked lesions on the leaves. These lesions usually occur early in the season and are how this pathogen is distinguished from other diseases. Top die-back is the necrosis of the top leaves and stalk of the corn. This occurs around the same time as grain formation. The stalk rot phase becomes prominent during the late reproductive stages of the corn life cycle. It is characterized by blackening of the pith tissue in the stalk and also of the rind, beginning at the nodes closest to the soil.〔 Along with these symptoms, seedling blight and post emergence damping off are also found. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glomerella graminicola」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
