Basal kernel blight is a barley disease that primarily impacts the malting and brewing industry since microorganisms present in diseased kernels may alter malt and beer quality. Basal kernel blight is characterized by dark brown discoloration on the embryo end of the kernel, and in Montana this disease is caused by Pseudomonas syringae pv. syringae. In this study we determined that the critical period of infection is from late milk to soft dough stages of kernel development and that high moisture is necessary during this period of infection and disease development. In addition, the use of sprinkler irrigation at soft dough may be applicable for evaluating susceptibility of cultivars under field conditions as statistical differences were found between cultivars.
