Potato pests can vary across Canada’s potato-growing regions. Whether they are new or notorious, their reach and severity depends upon Mother Nature’s whims.

Researchers recommend potato growers in the Pacific Northwest intensify their field scouting programs for the potato psyllids that spread the crop disease zebra chip.

Oregon State University researchers say they've found two fields in their region harboring thousands of volunteer potato plants infected with the Liberibacter bacterium that causes the crop disease zebra chip.

One year, it's the potato tuber worm;another year, it's the beet leafhopper.

Thanks to investigations by scientists-turned-detectives with the U.S. Department of Agriculture (USDA) and other agencies, potato growers in the western United States and abroad now know the identities of the pathogen-insect duo responsible for outbre...

In October, the University of Idaho College of Agricultural and Life Sciences confirmed that Idaho’s potato growers faced a new challenge to the state’s most famous crop with the arrival of Zebra chip.

A potato disease that arrived late this summer in the Pacific Northwest called zebra chip likely can't be spread by planting infected seed, new research suggests.

Zebra chip disease nearly destroyed a large USA potato growing business, its owner and chief executive told the Cambridge University Potato Growers Research Association conference earlier this month.

Zebra chip, a disease that affects potatoes, was recently found in the potato-growing regions of Washington, Oregon and Idaho. The discovery brings to focus the growing need for scientific answers – something that will be discussed at the SCRI Zebra Ch...

In light of the recent confirmation of zebra chip in Idaho, Focus on Potato, a nonprofit potato crop management resource, has made open access its presentation on Zebra Chip Disease of Potatoes by Gary Secor of North Dakota State University. This pres...

A potato pest from points south has reached Idaho, University of Idaho Extension specialists with the College of Agricultural and Life Sciences confirmed this week. It was reported last month in Oregon and Washington.

Zebra chip, a disease that annually costs Southwest U.S. potato growers millions of dollars in crop loss, has been found in Washington and Oregon. A USDA scientist and an Oregon State University plant pathologist confirmed zebra chip in tuber samples ...

A major pest called the tomato potato psyllid, has cost the potato industry over a $120 million since its initial discovery in 2006, according to a new report from Potatoes New Zealand. Ron Gall, Business Manager for Potatoes New Zealand, presented th...

AUSVEG CEO Richard Mulcahy said today that diseased potatoes had the potential to threaten the viability of the entire Australian potato industry if the Australian Federal Government allows potatoes to be imported for processing from New Zealand.

Developing a chemical attractant to monitor and manage the potato psyllid is the goal of a new cooperative agreement signed in March between the Agricultural Research Service (ARS) and the University of California (UC) at Riverside.

Since 2000, a mystery disease has struck some potato fields in Texas, Arizona, California, Nevada, and other western states, reducing tuber yields and quality.
