News on Potato Defects and Diseases from Europe

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.

A team of researchers tracking the 2014 population of the potato late blight pathogen have added to the 2013 data to extend the spatial diversity plots and combine this with novel genetic analysis tools that visualise the distribution and diversity of dominant clones and reveals novel genetically diverse isolates in some regions.

Potato growers and agronomists in he United Kingdom will be better prepared to cope with more aggressive blight strains this season, with a new BlightCast warning tailored to focus on infections now typically occurring earlier in the season at cooler temperatures.

Científicos encontraron un gen para ayudar a proteger las papas de una plaga que desató una devastadora hambruna en Irlanda en el siglo XIX.

In this week 'Nature Plants', scientists from Wageningen University and The Sainsbury Laboratory report the identification of a resistance gene that enhances resistance against potato late blight from a South American wild relative of cultivated potatoes.

Investigadores del Instituto Max Planck desarrollan papas resistentes al escarabajo de la papa usando la tecnología de ARN de interferencia.

Scientists at the NEIKER-Tecnalia Basque Institute for Agricultural Research and Development have studied the genetic structure of Phytophthora infestans —responsible for potato blight—.

Científicos del Instituto Vasco de Investigación y Desarrollo Agrario, NEIKER-Tecnalia han realizado el estudio de la estructura genética de Phytophthora infestans -causante del tizón tardío de la papa- y han identificado por primera vez en España la existencia del genotipo Blue13 (13_A2). El hallazgo es fruto de los resultados obtenidos en la tesis doctoral del ingeniero agrónomo Néstor Alor, presentada en la Universidad de Lleida y dirigida por el Dr. José Ignacio Ruiz de Galarreta.

Colorado potato beetles are a dreaded pest of potatoes all over the world. Now, scientists from the Max Planck Institutes of Molecular Plant Physiology in Potsdam-Golm and Chemical Ecology in Jena have shown that potato plants can be protected from herbivory using RNA interference (RNAi).

The Potato Demo Day is an easily accessible event for the Potato Sector. The programme is implemented at limited costs and in cooperation with participating companies from the sector.

Experts from the UK and India are working together to identify and develop novel environmentally-sustainable strategies to control plant pests, known as plant-parasitic nematodes to ensure global food production and security.

Researchers at the Universities of Dundee and Aberdeen have made a breakthrough in understanding how the microbial spores which cause potato blight are so effective at infecting plants.
