The fungus is internally seed borne (dormant mycelium within the embryo of the barley seed). PLP 06M-2017 Infection is favored by cool, humid conditions during flowering period of the host plant. When plants are infected at booting stage, bacterial blight does not affect yield but results in poor quality grains and a high proportion of broken kernels. Managementues for High Temperature Stress in Crops. Relatively high soil moisture and soil temperature are favourable for the infection. Disease is prevalent in more humid and higher rainfall areas. Source: NIPHM, Directorate of Plant Protection, Quarantine & Storage. The disease is soil borne and inoculums of fungi survive in soil. Disease is prominent when temperature is 10-20°C and high humidity.
