Note droplets of bacterial ooze. conditions, such as following artificial inoculation, it can reduce the yield by as much as 75 per cent, but under ordinary farm conditions the disease has not been known to cause much damage in Western Canada. Appearance—Seedlings grown from infected seed are at first chlorotic and become dotted with brown spots. The chlorosis may occur in stripes occupying various proportions of the leaf. Such plants are often stunted, but if they are only lightly affected, the stunting is not very noticeable. The disease is most easily recognized at heading time. Some of the infected leaves have brown stripes that resemble a V, an inverted V, or W. Such stripes always continue across the leaf from one edge to the other and separate the healthy tip from the diseased base. 46.
