Tilletia barclayana explained

Tilletia barclayana is a plant pathogen that infects rice, signalgrasspearl millet, and crabgrass. The pathogen corrupts the crops it infects, causing black busts to appear on the crops, which then become discolored and smutted.

History

Tilletia barclayana can live up to 2 years or more while in a host, and is found largely worldwide. Although the origin of the pathogen is unknown, it was first reported in the 1980s.

Impact

Tilletia barclayana spreads between nearby plants, leading to an increased loss. Due to this impact scientists are attempting to make these crops more resistant to the pathogen. As of now, the main method of controlling the pathogen is by pulling the infected crops directly from the ground.

Control

Out of salicylic acid and plant extracts of Ammi visnaga, Glycyrrhiza glabra, Artemisia judaica, Mentha viridis, Syzygium aromaticum and Eucalyptus globulus, M. viridis and S. aromaticum were most effective in prevention of T. barclayana infection.[1] All the tested solutions did provide some level of protection however.
