详细请见http://www.ent.iastate.edu/image ... 796.33anthracn.html和http://www.ipm.iastate.edu/ipm/icm/2001/6-18-2001/smallcorn.html。 “We also have started to see anthracnose lesions on small corn plants. Anthracnose leaf blight (caused by the fungus Colletotrichum graminicola) is usually one of the first leaf diseases to appear. The fungus survives in crop residue and its spores are splashed onto the leaves. Anthracnose is definitely more severe where corn follows corn. Symptoms are brown, oval, or elliptical spots (up to about 1/2 inch in length) with a dark brown or purplish border, often surrounded by a yellowed zone. There may be black speckles within the dead tissue. Sometimes the symptoms are limited to the leaf margins. Anthracnose can cause significant damage to very young plants and contributes to postemergence stand loss, but it appears that it has been too cold for this disease to develop much until now. As with the bacterial leaf diseases, we do not expect any economic impact of these early-season leaf infections this year.” |
