Fig. 2. The percentage of hop cones (n = 10 per week) that had Diaporthe humulicola detected using two different methods, plating of cone tissue onto potato dextrose agar (solid line) and a translation elongation factor 1-alpha–based TaqMan quantitative PCR assay that was run on DNA extracted from the cones used for isolation (dotted line). Cones were collected from the same plant in a research yard in East Lansing, Michigan, over 10 weeks (starting 22 May) in 2022.

The (TEF)-based TaqMan qPCR assay developed by Ross J. Hatlen et al. provides time-limited diagnosticians with a tool for the detection of #Diaporthe humulicola, the causal agent of halo blight of hop. Learn more: https://doi.org/10.1094/PDIS-11-24-2331-SR

C, Zoomed-out image of bine with conidial ooze. D, Ruptured pycnidia with conidial ooze that is dried and a newer ooze that is still wet.

Ross J. Hatlen and Timothy D. Miles outline symptoms and signs for halo blight of hop, offer information on the identification of the pathogen, and provide information on pathogenicity testing for #Diaporthe humulicola: https://doi.org/10.1094/PHP-02-25-0058-DG
