First report of Tilletia pulcherrima bunt on switchgrass (Panicum virgatum) in Texas
Plant Disease 92 (12), 1707-1707
Abstract: Some seeds of switchgrass (Panicum virgatum) plants grown in Texas, USA were observed with bunt symptoms and were darker and occasionally slightly swollen relative to noninfected seeds. The fungus Tilletia pulcherrima was isolated from the diseased plants. The identification was based on host and spore morphology. The ITS sequence was distinct from all Tilletia sequences in GenBank, including Tilletia barclayana on Panicum obtusum. T. indica, the Karnal bunt pathogen of wheat, has similar spores, occurs in Texas, and has quarantine status.
