Greater understanding of the biology of one of the most destructive plant viruses to potato crops will be the focus of a research hub at the University of Maine.

Native to the Rocky Mountains, the Colorado potato beetle has now spread to many parts of the world and quickly overcoming almost every pesticide thrown in its way. A new UVM study sheds light on how these insects become resistant so fast.

In a recent study published in the MPMI journal, scientists from CSU revealed that metabolites from S. chacoense contribute to disease resistance by altering the pathogenic behavior of Pectobacterium brasiliense, rather than inhibiting its growth or killing it.

The United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of Ralstonia solanacearum race 3 biovar 2 (RSr3b2) in a single variety of geranium plants located in a Michigan greenhouse.

Potato virus Y is the most economically important and devastating aphid-transmitted virus, affecting both tuber yield and quality. The virus is also a major cause of seed potato degeneration, which leads to regular flushing out of seed potatoes.

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).
