Interpretive Summary: Hop shoot proliferation disease has been described in Poland., and is associated with phytoplasma infection. Hop shoot proliferation occurs rarely and seems to be of little economic concern in most regions of hop production. Hop shoot proliferation is thought to be caused by a bacterium vectored by certain phloem-feeding insects. Control measures for hop shoot proliferation disease have not been reported, but prevalence and incidence of the disease dictate that control measures probably are not needed in most instances. A review of the body of knowledge on the pathogen and disease is presented.

Technical Abstract: Hop shoot proliferation disease has been described in Poland., and is associated with phytoplasma infection. Hop shoot proliferation occurs rarely and seems to be of little economic concern in most regions of hop production. Hop shoot proliferation is thought to be caused by aster yellows phytoplasma, group 16SrI-B, now reclassified as ‘Candidatus Phytoplasma asteris’, which is associated with symptomatic plants. A review of the body of knowledge on the pathogen and disease is presented.
