News on Potato Defects and Diseases from the United States

The National Potato Council (NPC) is pleased to award Washington Luis da Silva, a plant pathology Ph.D. student at Cornell University in Ithaca, N.Y., its 2014-15 Academic Scholarship.

Late blight, a fungal-like pathogen that affects potato and tomato crops, has been confirmed on Long Island for the sixth consecutive year.

A potato disease known as Late blight is threatening some Wisconsin potato fields, but growers are well aware and making strides to prevent it from spreading.

In this USDA research on soybean crops, researchers find a link between minimum winter temperature and pesticide use.

Whether you call them glassy ends, translucent ends, dark ends, jelly ends, or something even less flattering, sugar ends are a significant issue.

A University of Florida scientist has pinpointed Mexico as the origin of the pathogen that caused the 1840s Irish Potato Famine, a finding that may help researchers solve the $6 billion-a-year disease that continues to evolve and torment potato and tomato growers around the world.

Hairy nightshade and potato tuberworm (or potato tuber moth) are two economically important inhibitors to potato production. Two of the latest ‘Focus on Potato’ webcasts focus on these economically important potato pests.

Researchers at USDA's Agricultural Research Service are leaving no stone unturned when it comes to finding new ways of managing zebra chip disease and the insect that can spread it to potato crops.

Según una reciente investigación de las Universidades de Kansas y California-Davis, el Centro Internacional de la Papa y el Instituto Internacional de Investigación del Arroz.

Resultados de nuevos estudios por científicos con el ARS sugieren que un tratamiento con el ácido salicílico podría prevenir o reducir la infección de plantas de cultivos por el fitoplasma de la punta morada de la papa, el cual es una bacteria sin paredes celulares.

Jenifer Huang McBeath of the University of Alaska Fairbanks has been researching biological controls and developing environmentally friendly methods for farmers to combat plant diseases since 1985. She never intended to switch her focus to potatoes...

According to United States Department of Agriculture’s crop production predictions, average potato yield per acre increased during the 2013 season.

In an effort to propel this upward trend into the New Year, Bayer CropScience launched its Potato Perspectives Survey during Potato Expo in San Antonio, Texas, Jan. 8-10, 2014.

This webcast by the Plant Management Network on Potato Psyllids, responsible for the transfer of the Zebra chip disease consists of two parts:

Although late blight has been confirmed in 12% of Wisconsin’s counties, growers took aggressive action to control the disease and are predicting full yields and high quality potatoes of all varieties this season.

About the same number of potato psyllids have been caught on sticky traps in Idaho fields this season as by this time last summer, but far fewer of the tiny, winged insects have tested positive for the Liberibacter bacterium, which causes the crop dise...

Key Technology announces that it has signed an exclusive licensing agreement with EVK DI Kerschhaggl GmbH and Insort GmbH to deploy Chemical Imaging Technology (CIT®), an advanced value-added hyperspectral solution, in Key’s products, further enhancing...

Volunteer potato plants growing from seed infected with zebra chip are likely too few in number and survive too briefly to contribute to the spread of the crop disease, according to new Oregon State University research findings.

As the potato growing season begins, The Washington State Potato Commission (WSPC) will provide free Integrated Pest Management (IPM) supplies for Washington’s potato growers.
