Bacterial disease of broomcorn. (Hothouse, U. S. Department of Agriculture, spring of 1905.) 



Disease not complicated by aphides. The signs consist of gradually elongating red or red-brown stripes on a green background. In later stages the stripes coalesce 

 and the leaves shrivel. Under surface of diseased areas often covered by red crusts the dried-down, bacterial ooze from interior of leaves. The infections were 

 by way of the stomaU and these spots are about six weeks old.
