A disease of rice caused by the bacteria Xanthomonas campestris pv. oryzae. The leaf stage of BLB is the most widespread and, therefore, causes the most damage.

The lesions develop rapidly parallel to the veins and extend laterally to the healthy regions. In extreme cases, a large portion of the entire leaf blade becomes infected, turns yellow or dirty white, and finally dies.
