News on Phytophthora from the United States

Andy Diercks, a fourth-generation potato farmer from the small village of Coloma in central Wisconsin, is blunt about the difficult realities facing family-owned farms today.

Researchers at North Carolina State University identified the South American Andes as the origin of the Irish potato famine pathogen, Phytophthora infestans

In an examination of the genetic material found in historic potato leaves, North Carolina State University researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.

The device has the potential to transform the way that farmers detect and manage plant diseases, leading to more efficient and sustainable agriculture practices.

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.

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

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.

Agricultural Research Service (ARS) scientists in Albany, California, have found a way to streamline the process that scientists use to insert multiple genes into a crop plant. Simplot is planning to use it to introduce multiple genes into potatoes to make them resistant to late blight

Idaho potato fields looked good as of early July as plants closed in over rows, signaling the tubers are preparing to grow strongly amid the hot-day, cool-night march toward harvest.

Jean Ristaino, a professor at North Carolina State University with emphasis in research on Phytophthora infestans, reported on a late blight look-alike from tomato and potato in North Carolina.

Potato growers in Idaho will now have the opportunity to learn about the presence of damaging fungal pathogens much earlier, thanks to the efforts of research staff at the University of Idaho. The research team, led by James Woodhall, has placed 14 spore samplers in potato fields across the Snake River Valley.

Benjamin 'Benjy' Firester, 18, of New York City, won the top award in the Regeneron Science Talent Search 2018 with a mathematical model that uses disease data to predict how weather patterns could spread late blight spores.

Wisconsin Governor Scott Walker signed two new measures involving the potato industry last Wednesday. One law makes use of certified seed potatoes mandatory, the other enforces a faster response to the presence of late blight

The US federal government has given the final OK to three more types of potatoes genetically engineered by Boise’s J.R. Simplot Co. to resist Phytophthora - the pathogen that caused the Irish potato famine.

North Carolina State University research delves into the movement and evolution of the pathogen that caused the Irish potato famine in the 1840's - Phytophthora infestans -, which set down roots in the United States before attacking Europe

The heart of "Potato Country" in northeast North Dakota was devastated by baseball size hail that lasted up to 35 minutes last Tuesday night.

Late blight is a potentially destructive disease of potato and tomato crops worldwide that can result in significant losses if detected too late, diagnosed incorrectly, or if not treated properly.
