News on Phytophthora from Europe

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.

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.

Potato crops in Britain are facing high blight pressure this season, demanding the best possible protection under extremely challenging application conditions.

The blight fungicide containing Initium and dimethomorph, Zampro DM, has had reduction of tuber blight incidence added to its label, in addition to the control of late foliar blight.

As part of the Potato Council’s ‘Fight against blight’ campaign, the mapping of late blight outbreaks has demonstrated outgrade piles remain a significant source of blight in potato crops.

The decision support system “Blight Management” (“Skimmelstyring”) could in the future give Danish potato growers more effective control of potato late blight and reduce the use of fungicides.

The very early discovery of a new potato blight strain in Britain doesn't mean that spray programmes will have to change this year, agree researchers and agronomists.

BASF Plant Science will again conduct field trials this year with genetically optimized potatoes which are undergoing the EU approval process.

Wageningen UR ontwikkelt een milieuvriendelijke aardappel met resistentiegenen tegen de agressieve aardappelziekte. Het is onduidelijk of de introductie van deze aardappel kans van slagen heeft in het technofobe Europa. Goede kans dat-ie straks in Chin...

De vraag naar Bintje pootgoed laat nog even op zich wachten en ook voor deze maand verwacht de handel vanuit Brabant en België nog weinig vraag naar Bintje. Ook zal de vraag naar Bintje iets lager zijn dan andere jaren.

In het Belgische Wetteren wordt dit jaar opnieuw een ggo-aardappelproefveld aangelegd. De Fortuna-lijn van BASF wordt echter uitgesloten. Op die manier zijn alleen wetenschappelijke instellingen betrokken bij het onderzoek. Dat is één van de voorwaarde...

Teagasc are applying to the EPA for a licence to undertake a series of field studies using GM potatoes resistant to potato late blight disease to determine the potential impact this technology could have on our ecosystems. As part of the 22 partner ‘A...

Phytophthora infestans, the causal agent of late blight, has evolved to overcome fungicides and major resistance genes that have been bred into commercial potato cultivars.

BASF Plant Science applied today for EU approval for Fortuna, a genetically optimized table potato.Fortuna has a wild potato’s natural protection to late blight, a disease causing severe problems in agriculture.
