context_page_description: Glomerella graminicola is an economically important crop parasite affecting both wheat and maize where it cause the plant disease Anthracnose Leaf Blight. Certain cereal varieties that have been genetically engineered. may be more susceptible to the teleomorph phase of the fungus.
context_section_description: G. graminicola is an anamorphic fungus which is identified as  Colletotrichum graminicola   in the teleomorphic phase . It is the  anamorphic phase of Colletotrichum graminicola, causes anthracnose in many cereal species including maize , sorghum, barley and wheat where the production of fruiting bodies cause symptoms to appear in the host plant. 
   Corn anthracnose leaf blight, is the most common stalk disease in maize and occurs most frequently in reduced-till or no-till fields. 
  C. graminicola is also a  pathogen of many turfgrasses, e.g., bluegrass, ryegrass, fescue.  The fungus can infect many different parts of the host plant, typically the kernels and tassels of Maize, roots, leaves, stalk and husks. The most common area of infection is the stalk. 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.
