News on Phytophthora

When a pathogen attacks a plant, infection usually follows after the plant’s immune system is compromised.  A team of researchers at the University of California, Riverside focused on Phytophthora and deciphered how it succeeded in crippling the potato...

Researchers led by Professor Bruce Fitt, now at the University of Hertfordshire, have used modern DNA techniques on late nineteenth-century potatoes to show how the potato blight may have survived between cropping seasons after the Irish potato famine ...

As the annual potato harvest begins, Wisconsin farmers continue to check their fields for late blight, the ferocious plant disease that caused the 1848 Irish potato famine and fueled massive emigration from Ireland.

The increase in the concentration of CO2 in the atmosphere can have a positive influence on the potato yield. This is according to Anton Haverkort of Plant Research International, part of Wageningen UR, on 22 August during the bi-annual Potato Demo Day at Westmaas.

A group of campaigners in the Irish Republic has been refused a legal challenge over the first trial of a genetically modified potato crop. In July, the Environmental Protection Agency (EPA) gave the go ahead for a gm blight-resistant potato crop to be tested in County Carlow.

The Agri-Food and Biosciences Institute and CAFRE, Greenmount Campus have issued a further potato blight warning.

The NDSU Potato Blightline for August 20th sponsored by Syngenta Crop Protection has been issued.

In France, according to the UNPT, blight pressure remains strong and there are signs of early senesce in some crops.

Ireland's environmental protection agency has approved the first trial of a genetically modified potato crop.

Potato growers could achieve potential savings of more than €450/ha if they used a blight-resistant genetically modified (GM) potato variety instead of a conventional variety.

La Agencia de Protección Ambiental (EPA) dio su visto bueno para las pruebas de una papa genéticamente modificada (GM) que es resistente al tizón de la papa. En los próximos cuatro años se sembrarán en Irlanda dos hectáreas con esta papa genéticament...

The Environmental Protection Agency (EPA) has today given consent to Teagasc, Oak Park, Co Carlow, to carry out field trials on a genetically modified (GM) potato line with improved resistance to late potato blight.

One of the scourges of the potato crop – blight – has now been found in all the major growing areas of Scotland, with infestation levels running well ahead of average.

Potato growers are facing many weather-related challenges and recent warm, wet weather has led to a massive increase in the number of Smith Periods this year so far, says Potato Council executive and blight specialist Gary Collins.

The horticulture department and Krishi Vignana Kendra had organised a demonstration of spraying pesticides in Narasipura in the wake of spread of blight disease for potato crop under Salagame hobli in the taluk recently.

Home gardeners and commercial growers are alerted of the potential introduction of late blight this growing season, as it has been confirmed in Suffolk County.

Dutch tests on a new strain of potato blight similar to that discovered for the first time in the UK last year have shown some isolates have reduced sensitivity to the common active fluazinam used to control the disease.
