Abstract
Common hops, Humulus lupulus, are a commercially important crop in the United States, with an increasing number of hop yards being established in the Northeast. Historically, there have been two major fungal diseases of commercial hops: downy mildew and powdery mildew. In 2018, a new fungal disease was observed at two research hop yards in Connecticut. This new pathogen affected all hop cultivars being grown and caused leaf spots and browning of cones. The causal organism was isolated and Koch?s postulates were performed to confirm pathogenicity. The disease symptoms were similar to the previously described Phoma wilt, however morphological and phylogenetic analyses placed the causal organism as a new species of Diaporthe. We propose the name Diaporthe humulicola, for this new fungal species that infects common hops in Connecticut. The disease increased under hot, humid conditions, which are present during the summer in the Northeastern United States, as well as other parts of the country. The proper identification and monitoring of this pathogen are important to inform growers of this new threat. An in vitro assessment of fungicide sensitivity revealed pyraclostrobin and boscalid inhibited D. humulicola growth in culture and should be further assessed for field efficacy to control this new disease on hops.
