The moderate temperatures and wet conditions experienced throughout the High Plains from May to July were conducive for the development of bacterial blight (Fig. 1). An increase in the disease was observed across most of the region with observations of bacterial blight-like symptoms occurring on varieties that had previously been documented as being resistant or immune.

Initial ratings of a research trial near Plains, Texas, found the disease to be present in most all plots with disease incidence averaging nearly 25 percent. Upon closer examination, the ratings were found to be incorrect resulting from erroneous labeling of plots in the field. This is good news from a production perspective, as the updated disease ratings with correctly labeled plots immune.
