Resources
Extension bulletins are great resources for PVY, PMTV and powdery scab information and are available from multiple universities in the U.S.
PVY
-
Management of potato virus y (PVY) in Wisconsin seed potato production, Bulletin A3951 (pdf)
Potato Virus Y is an aphid-transmitted virus that causes disease in numerous solanaceous crops including tomato, pepper, tobacco and potato. - Portable test kits for diagnosing potato diseases, Bulletin 883 (pdf)
Misdiagnosing a potato disease can be very costly if unnecessary fungicide applications or other control measures are implemented. - Potato virus Y and organic potatoes in Western Washington, Bulletin FS312E
Specialty potatoes at the rural/urban interface in western Washington frequently are grown organically on small farms and in home gardens that sometimes adjoin commercial potato fields. - Potato virus y management for the seed potato producer, Bulletin CIS 1165 (pdf)
One of the most serious challenges facing seed potato producers is managing Potato virus Y, also know as “common mosaic” or “potato severe mosaic.”
PMTV
- Potato tuber viruses: Mop-top management, Bulletin A1777
-
The potato mop-top virus is spreading throughout the potato-growing regions in the U.S.
- Potato mop-top virus (PMTV), Bulletin 2437 (pdf)
The disease, potato mop-top, is caused by the virus, potato mop-top virus.
Powdery Scab
- Powdery scab of potatoes, Bulletin 2436 (pdf)
The appearance of the disease is variable from year to year, being dependent upon a conducive environment.
- Powdery scab of potatoes, Bulletin PP1891
Spongospora subterranea f. sp. subterranea (referred to as S. subterranea), the causal agent of powdery scab and root gall formation in potato, is a soil- and tuber-borne fungus like pathogen
Monitoring Insects with Bucket Traps
Learn how to set up a bucket trap for monitoring flying insects. This method allows farmers, gardeners or other pest managers to learn more about insects entering their crops. The method works by filling a bucket with water, which traps insects. Insects are then observed to learn about their movement in and out of fields. This method helps growers like seed potato farmers learn about potential pathogens entering their field. Learn about equipment needed to use this method and tips for troubleshooting.
