Papaya ringspot virus (PRSV) is a pathogenic plant virus [1] in the genus Potyvirus and the virus family Potyviridae which primarily infects the papaya tree.. The virus is a non-enveloped, flexuous rod-shaped particle that is between 760–800 nm long and 12 nm in diameter.
As the disease progresses the damaged areas become slightly larger and then dry up and fall away, leaving BB-sized holes behind. As the fungus spreads, more leaf tissue is damaged until the leaf falls. Significant infections can reduce the amount of photosynthesis that can occur, weakening the plant, and decreasing fruit production. The ...
Prunus necrotic ringspot virus (PNRSV) is a plant pathogenic virus causing ring spot diseases affecting species of the genus Prunus, as well as other species such as rose (Rosa spp.) and hops (Humulus lupulus). [1] [2] PNRSV is found worldwide due to easy transmission through plant propagation methods and infected seed. [3]
The document includes such specific recommendations as "Avoid overhead irrigation of high-risk plants"; "After every crop rotation, disinfect propagation mist beds, sorting area, cutting benches, machines and tools to minimize the spread or introduction of pathogens"; and "Nursery personnel should attend one or more P. ramorum trainings ...
