The World Potato Congress (WPC) continues with its webinar series in its 2020 on January 24, with a webinar featuring Dr. David Douches of 'Feed the Future – Biotechnology Potato Partnership'

Scientists have developed a user-friendly online tool called Uniqprimer, which quickly and automatically designs species-specific DNA tags (also known as primers) for detecting pathogens such as Dickeya dianthicola using DNA testing.

A research team has identified a virus infecting Phytophthora infestans, the pathogen causing late blight in potatoes and tomatoes, that appears to increase the pathogen's ability to cause the disease.

Researchers in the WARF Accelerator program are using advanced imaging technology to detect late blight in potatoes, which famously led to the Irish potato famine in the mid-nineteenth century.

Its harvest time for many in the potato industry, and those not quite to that point, harvest will be here before you know it. Washington State University’s Tim Waters said growers need to continue to watch for pests.

The National Potato Council (NPC) has named University of Wisconsin-Madison graduate student Sofia Giron the winner of its annual $10,000 scholarship. Giron is a fourth-year grad student studying plant pathology.

Late blight has been confirmed in a potato field in central Wisconsin.

WSU plant pathologists Kiwamu Tanaka and Cynthia Gleason are exploring novel approaches to protect the potato crops against nematodes and scab - mobilizing nature itself.

Ongoing studies at the University of Idaho’s Aberdeen Research & Extension Center seek to help seed potato growers avoid a chronically troublesome disease spread by aphids, called potato virus Y, writes John O’Connell in the Idaho State Journal.

Aphids and the plant viruses they transmit cause billions of dollars in crop damage around the world every year.

Plant breeders and geneticists of Cornell University have released more than 50 potato varieties since 1908. Now they are expanding their efforts to make more wild potato seeds available to potato breeders around the world.

In his presentation at the the 2018 Potato Expo, Dr. Chad Hutchinson discusses the benefits of using Chloropicrin in potato production. Chloropicrin increases production efficiency, profit potential for potato growers, and it also improves soil health.

ARS Researchers studied potato tubers from the Klamath Basin in Oregon infected with the causal bacteria of zebra chip disease. They confirmed the presence of the pathogen but did not identify the sample as one of the six known varieties (haplotypes).

Idaho potato farmers are getting paid about the same amount for their spuds as they're investing in raising them, according to a University of Idaho Extension agricultural economist's report, presented during the Idaho Potato Conference.

Effective October 10, the Animal and Plant Health Inspection Service (APHIS) added an 87-acre field to the pale cyst nematode (PCN) infested area in Bingham County, Idaho.

The problem for North Carolina’s sweet potato farmers is knowing whether the drenching rains unleashed by hurricane Florence will have the same effect as being inundated by a flooded pond or creek. Some sweet potato fields received as much as 30 inches.

The Washington State Potato Commission, headquartered in Moses Lake, Washington, has been pleasantly surprised by the weather and its impact on this year’s potato crop in the state.

Farmers, researchers and members of the public gathered at the University of Maine’s Aroostook Research Farm in Presque Isle last Wednesday to learn about the latest in potato research.
