Phosphorous acid based products can be an effective control for postharvest diseases when applying best practices. In the presentation. Learn more in the latest ‘Focus on Potato’ presentation “Phosphorous Acid and its use in Potato Post-Harvest Situations,”

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.

Cómo funciona esta red fue uno de los temas del seminario de Agrometeorología que se realizó en el INIA-Quilamapu para promocionar instrumentos tecnológicos entre los agricultores de la región.

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.

Crop management and protection practices that help prevent soil-borne diseases in potato crops will be the key focus of a special potato research and development (R&D) workshop to be held in Berrigan, NSW, Australia

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.

Predicta Pt, the South Australian Research and Development Institute (SARDI) soil testing service for the potato industry, has received the John Deere Productivity Partner Award at the 2014 AUSVEG Awards for Excellence in June.

Late blight, a fungal-like pathogen that affects potato and tomato crops, has been confirmed on Long Island for the sixth consecutive year.

A potato disease known as Late blight is threatening some Wisconsin potato fields, but growers are well aware and making strides to prevent it from spreading.
