News on Potato Defects and Diseases from the Americas

Potato is the most important crop in Peru and late blight is the main disease affecting the crop. However, new varieties that are resistant to late blight often lack other traits that farmers and consumers prefer.

Greater understanding of the biology of one of the most destructive plant viruses to potato crops will be the focus of a research hub at the University of Maine.

Los productores del Grupo de Transferencia Tecnológica GTT de Semilla de Papa de Los Muermos volvieron a reunirse en forma presencial luego de meses realizando sólo actividades virtuales.

Sembrado mayormente por pequeños agricultores, es uno de los cultivos más relevantes en Chile y puede ser amenazado por una bacteria contra la que aún no hay nada efectivo para contrarrestar. Las pérdidas son de gran impacto social.

Funcionarios de la entidad recolectaron muestras fitopatológicas y entomológicas que son analizadas en Colombia e Italia.

Con la finalidad de encontrar nuevos materiales que se adapten a las zonas paperas de Honduras se establece un ensayo nacional de evaluación de 36 clones de papa.

The Prince Edward Island Potato Board is excited to share with potato farmers and industry partners the launch of a new podcast, Spudchat.

A team effort led to Alberta being declared Potato Cyst Nematode (PCN) free – improving trade prospects for producers.

The Canadian Food Inspection Agency has lifted its voluntary suspension of export certification for P.E.I. seed potatoes, allowing trade to the United States to resume.

Seed potato exports from Prince Edward Island to the United States halted last fall now closer to resuming.

El Ministerio de Desarrollo Agrario y Riego, a través del Servicio Nacional de Sanidad Agraria – SENASA, mantiene el monitoreo preventivo de la plaga Tecia solanivora, conocida también como ‘Polilla Guatemalteca’

Native to the Rocky Mountains, the Colorado potato beetle has now spread to many parts of the world and quickly overcoming almost every pesticide thrown in its way. A new UVM study sheds light on how these insects become resistant so fast.

In a recent study published in the MPMI journal, scientists from CSU revealed that metabolites from S. chacoense contribute to disease resistance by altering the pathogenic behavior of Pectobacterium brasiliense, rather than inhibiting its growth or killing it.

The Canadian Food Inspection Agency (CFIA) has recently confirmed the presence of potato wart in two fields on a farm in Prince Edward Island (PEI). Potato wart is a regulated quarantine pest in Canada.

Two research scientists on P.E.I. have spent their summer trying to grow a better potato, more resistant to scab and greening, which are both costly problems for potato growers.

Nueva plaga afecta los cultivos de papa en la provincia Ecuatoriana del Carchi. El insecto detectado en laboratorios de agro- calidad, luego de varios análisis y tomas de muestras en cultivos de papa es combatido a través de un manejo integrado con escuelas de campo.

A key requirement for a longtime potato storage is that the storage conditions match the needs and end use of the crop. These requirements of can be assessed before harvest by doing several test digs which allow to determine the distribution and level of tuber infection.

The International Potato Center (CIP), in partnership with research and development institutions in Ecuador and Peru, has developed a low-tech tool to help farmers optimize fungicide's use.
