News on Potato Defects and Diseases

Key Technology introduces hyperspectral imaging on its popular ADR® 5 automatic defect removal system for potato strips to detect and remove sugar ends.

Cómo la enfermedad afecta la producción de papa en Argentina, Bolivia, Colombia, Chile, Costa Rica, México, Perú y Uruguay [Audio y resúmenes].

Following the discovery of potato wart on Prince Edward Island (PEI) in August the Canadian Food Inspection Agency (CFIA) notified the USDA’s Animal and Plant Health Inspection Service (APHIS) of temporary mitigation efforts by CFIA.

La presente guía tiene por finalidad asistir a los profesionales y técnicos a cargo de los ensayos diseñados para seleccionar genotipos de papa con resistencia a esta enfermedad.

Insecto que fue reportado por primera vez en Honduras en el año 2002, por técnicos del Departamento de Protección Vegetal de la Fundación Hondureña de Investigación Agrícola (FHIA). Esta hoja técnica muestra cómo se disemina y monitorea.

Growers of the potato variety Lamoka used for chip processing have seen a higher than normal incidence of blackleg in their fields this summer.

Su establecimiento se llevó a cabo en el XXVI Congreso bienal de la Asociación Latinoamericana de la Papa (ALAP), celebrado en la ciudad de Bogotá (Colombia) entre el 28 de septiembre y el 2 de octubre de 2014.

In a study published this summer, scientists of the Washington State University found that potato virus S (PVS) breaks down late blight resistance in potato.

While weed resistance issues have been grabbing many headlines over the past few years, fungicide resistance has become an increasingly important issue this growing season—and likely for future growing seasons if sound resistance management practices are not adopted.

Researchers of the Institute of Ecology (INECOL) in Mexico have identified a fungus capable of feeding on nematodes. Combining this biological control with other methods in an integrated management system reduced the golden nematode population by up to 90 percent in two years.

New Zealand Potato production in 2013, at 525,000 metric tons, was marginally (5%) ahead of 2012 production. t is likely planted areas in 2014 will be similar to 2013, with production in the range of 500,000 to 550,000MT.

The number of cases of a late blight (Phytophthora infestans) continues to grow on Prince Edward Island.

In Alberta, late blight occurs infrequently, but can have devastating impacts in the years when it reaches epidemic levels.

Científicos de la Red de Biodiversidad y Sistemática, del Inecol, localizaron y probaron con efectividad un hongo capaz de alimentarse del nematodo. Este avance permitirá controlar biológicamente la plaga, anular el uso de productos químicos y contribuir a disminuir el impacto de la agricultura en la ecología de la región.

Continued wet August weather has caused late blight infections to proliferate throughout Eastern Idaho, according to University of Idaho Extension potato pathologist Phil Nolte.

The National Potato Council (NPC) is pleased to award Washington Luis da Silva, a plant pathology Ph.D. student at Cornell University in Ithaca, N.Y., its 2014-15 Academic Scholarship.

The Canadian Food Inspection Agency has confirmed a case of potato wart in a Prince Edward Island field.
