Abstract:The hop (Humulus lupulus L.) is a dioecious perennial climbing plant grown commercially worldwide. Wild hops are widely distributed throughout the Northern Hemisphere, Europe, Asia, and North America (Neve, 1991). In the Southern Hemisphere, some of the leading hop-producing countries include South Africa, Australia, and New Zealand. Brazil began hop production less than 5 years ago. In January 2019, amphigenous white powdery circular fungal colonies were observed on the leaves and stems of hop plants (cultiva… Show more
“…However, during the last decade, attempts at hop cultivation in Brazil have been successfully initiated (Durello et al 2019;Pinto et al 2022). As the cultivated area expanded, so unreported diseases started to appear, namely: root knot nematode (Gonsaga et al 2021), powdery mildew (Fagherazzi et al 2021), Fusarium canker (Pinto et al 2022) and, recently, Cercospora leaf spot (Pereira et al 2022).…”
Paramyrothecium foliicola is reported for the first time in Brazil and worldwide causing leaf spots on hop (Humulus lupulus). The fungus was identified with a combination of morphological and molecular information. The pathogenicity of P. foliicola to hop was demonstrated through inoculations under controlled conditions.
