马铃薯缺陷和疾病 来自欧洲

Blackleg, caused by strains of soft rot bacteria known as Dickyea, has traditionally had little impact on North American potato production, but it now appears to be on the move throughout Europe and could increasingly threaten growers in the Eastern United States.

A team of scientists from The Sainsbury Laboratory (TSL) and The Genome Analysis Centre (TGAC) have developed a new method to accelerate isolation of plant disease resistance genes and - using their new method - a brand new source of blight resistance genes in Solanum americanum, a wild relative of the potato.

La Universidad de la Laguna en las Islas Canarias (España) adelanta un proyecto con varios agricultores para controlar biológicamente a la polilla guatemalteca.

Research to develop potatoes with sustainable resistance against phytophthora via genetic modification with genes from wild potatoes and good resistance management ended with the publication of the scientific results. The approach resulted in potato plants which require 80% less chemical control.

La Consejería de Agua, Agricultura y Medio Ambiente alerta a los productores que se ha detectado en zonas de Galicia, Asturias y Andalucía la presencia de una plaga de cuarentena denominada 'epitrix similaris', conocida como pulguilla de la patata (o papa).

Dr Jon Pickup, Head of Virology & Zoology at Science & Advice for Scottish Agriculture (SASA) will lead on one of three AHDB Potatoes Fellowship Awards, specifically seeking to secure critical potato nematology expertise for the future.

La Xunta de Galicia declara su presencia en los ayuntamientos coruñeses de Ferrol, Narón y Neda y establece una serie de medidas fitosanitarias para combatirla.

El Cabildo de Tenerife ha emprendido desde 2000 una cruzada contra una de las plagas habituales del campo tinerfeño: la polilla de la papa.

On the way from field to fork, more than half of the potato harvest is lost. This is according to a new study conducted by researchers from Agroscope and ETH Zürich.

The Dutch Association of Arable Farmers of (VTA) finds an average yield of 53.622 kg/ha, 8% below last year and on par with the 5-year average. Although tubers are large this season, the VTA predicts low factory yields as a result of a host of quality issues, resulting in an increased demand for potatoes per ton finished product.

Research shows that crops with stacks of two or more resistance genes from closely related species, introduced into the crop via for instance genetic engineering, combined with the simultaneous introduction of resistance management, can ensure the long-term resistance of these plants to economically significant and aggressive diseases.

The North-western European Potato Growers (NEPG) expect the total potato production (excluding seed and starch potatoes) of this year' s harvest to amount to 24.5 million tonnes. This is 14.1 percent below the potato production last year and 2.9 percent below the 5-year average.

In the annual VTA sampling of the development of the Dutch potato crop development, mid August a yield was found 16% lower than last year and 7.1 below the 5 year average.

Scientific results of the potato field trials in Flanders and the Netherlands demonstrate that gene stacking is necessary for a strong and lasting resistance to late blight (Phytophthora infestans).

Researchers in the United Kingdom aim for a new commercial potato that resists many of the worst vulnerabilities of potato crops around the world.

Desde el Cabildo de Tenerife no descartan que se pudiese producir un aumento de la enfermedad en la presente cosecha, sobre todo si las temperaturas experimentan una subida.

El evento se realizó en Brazov, Rumania, entre el 10 y 13 de mayo.
