The following testing and therapy services are available from the National Clean Plant Network for Fruit Trees (NCPN-FT),Washington State University, 24106 N. Bunn Road, Prosser, WA 99350. Further information on this program and related issues can be viewed on the Internet at: http://ncpn-ft.org/
Test protocols for virus and virus-like agents that affect tree fruit cultivars are:
- Woody indicator tests in the greenhouse or field.
- Herbaceous indicator tests in the greenhouse.
- Polymerase chain reaction (PCR) tests for phytoplasma.
- cRNA hybridization for selected viroids.
NCPN-FT also provides virus therapy for infected deciduous tree fruit cultivars of commercial importance.
Additional virus testing is provided by the WSU ELISA Testing Laboratory where a range virus assays are conducted using enzyme-linked immunosorbent assay (ELISA) or Polymerase Chain Reaction (PCR). Testing by this lab is available for the following viruses.
- Apple trees: apple chlorotic leafspot virus, apple mosaic virus, tomato ringspot virus
- Asparagus: asparagus virus 1, asparagus virus 2, tobacco streak virus
- Beans: alfalfa mosaic virus, bean common mosaic virus, bean common necrosis virus, cucumber mosaic virus, peanut stunt virus, tobacco ringspot virus, tobacco streak virus, tomato ringspot virus
- Corn: high plains disease virus
- Grapes: grape leafroll virus
- Stone fruit trees: apple mosaic virus, cherry leafroll virus, prune dwarf virus, Prunus necrotic ringspot virus, tomato ringspot virus
- Peas: pea enation mosaic virus, pea leafroll virus, pea seedborne mosaic virus
- Roses: apple mosaic virus, Prunus necrotic ringspot virus, tobacco streak virus
- Small fruits and berries: tobacco streak virus, tomato ringspot virus
- Vegetables: cucumber mosaic virus, squash mosaic virus, tobacco ringspot virus
