Abstract
The isolate DI of Exserohilum turcicum (Pass.) Leonard S in the corn group, the symptoms were spherical red-brown, water soaked lesions that enlarged into oblong grayish-black lesions and finally the leaves became blighted and died; in the grass group, symptoms of the pathogen included small, single brownish to dark brown lesions. Toxin from the crude extract of the E. turcicum was prepared by culturing the fungus on PDB for 2 wk at room temperature on a rotary shaker. The mycelia mass and spores were extracted with 10% ethyl acetate followed by methanol and hexane. The extract was inoculated on the sweet corn variety Hibrix3. After 4 days, the symptoms of the toxin on the plant leaves were similar to the symptoms developed by natural and/or artificial inoculation of the fungal pathogen.
