News on Potato Defects and Diseases from the Americas

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.

The United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has confirmed the detection of Ralstonia solanacearum race 3 biovar 2 (RSr3b2) in a single variety of geranium plants located in a Michigan greenhouse.

An interview with co-editors, Dr. Hugo Campos, Director of Research and Oscar Ortiz, CIP’s Deputy Director General of Research and Development at the International Potato Center.

More than $3 million is being invested in studying a major cause of potato yield reduction in Prince Edward Island and other spud-growing areas in Canada.

Potato virus Y is the most economically important and devastating aphid-transmitted virus, affecting both tuber yield and quality. The virus is also a major cause of seed potato degeneration, which leads to regular flushing out of seed potatoes.

A growing number of Prince Edward Island potato farms are taking advantage of new technology to improve their use of crop protectants, including fungicides used to prevent late blight.

Se mantiene la Alerta Roja en algunos sectores de la provincia de Osorno, Chile, debido a la presencia de tizón tardío que afecta a cultivos de papas. Por esto, agricultores de la zona y desde la Unión Comunal de Juntas de Vecinos Rurales acusan poca ...

The World Potato Congress (WPC) continues with its webinar series in its 2020 on January 24, with a webinar featuring Dr. David Douches of 'Feed the Future – Biotechnology Potato Partnership'

The International Potato Center has published an open source book on potato research: 'The potato crop: its agricultural, nutritional and social contribution to humankind'.

Scientists have developed a user-friendly online tool called Uniqprimer, which quickly and automatically designs species-specific DNA tags (also known as primers) for detecting pathogens such as Dickeya dianthicola using DNA testing.

A research team has identified a virus infecting Phytophthora infestans, the pathogen causing late blight in potatoes and tomatoes, that appears to increase the pathogen's ability to cause the disease.
