Tilletia barclayana
Tilletia barclayana is a plant pathogen that infects not only rice but also signalgrass, pearl millet, and crabgrass. The pathogen corrupts the crops it infects, causing black bust to appear on the crops, which become discolored and smutted. [1][2][4]

History
The pathogen can live up to 2 years or more while in a host and is located in various places around the world. Although the origin of the pathogen is unknown, it was first reported in the 1980s. [1][4][5]
Impact
The impact that Tilletia Barclayana has on these crops is that it infects many crops, leading to an increased loss. Due to this impact scientists are attempting to help make these crops resistant to the pathogen. As of now, the main method of controlling the pathogen is by pulling out the crop directly from the soil it is planted in. [1][2][3]
