Abstract
Description
Viruses and viroids cause losses in hop production and
are very difficult to eliminate, they spread easily and infected
plants become a source of infection for other plants in the hop
garden. Hop infected with viruses or viroids usually do not show
any symptoms of disease, which makes it difficult to identify in-
fected plants and prevents their elimination from the plantation.
Monitoring is of utmost importance to detect and eradicate at an
early stage first sources of infection with pathogens that have po-
tentially catastrophic impacts on hop production. The aim of the
study was determine the incidence of Hop latent virus (HpLV),
Arabis mosaic virus (ArMV), Hop stunt viroid (HSVd), Apple
fruit crinkle viroid (AFCVd) and Citrus bark cracking viroid
(CBCVd) in Polish hop gardens. Hop leaves from commercial
hop gardens and a propagation facility were tested by RT-PCR.
On the basis of the obtained results, HpLV was found to occur in
a few hop gardens in all regions of hop cultivation in Poland.
HSVd was found in one hop garden and ArMV, AFCVd and
CBCVd were not found in any of the tested samples. The results
provided knowledge about these pathogens and will be useful in
effective management of the risk of these dangerous diseases.
