Industry:Agriculture
A bacterial disease of rice caused by Xanthomonas oryzae pv. oryzicola. The organism attacks chiefly the parenchymatous tissue between the leaf veins and, in the early stages, remains confined to the interveinal spaces. It may enter the leaf through the stomata or through wounds which are mainly caused by storms. The symptoms manifested are the appearance of fine, interveinal, long or short lines which are water-soaked and grayish. The lesions extend and coalesce to form larger patches and become yellow from the death of cells. At this stage, the symptoms are difficult to distinguish from those of bacterial leaf blight. The disease is limited to the tropics.
