News on Phytophthora from the Americas

A new potato variety, CIP-Asiryq, developed by the International Potato Center and Indigenous farmers in Peru, resists late blight, cuts fungicide use, cooks faster, and boosts farmer income, offering a climate-resilient solution worldwide.

Los productores de papa de la Asociación Frutihortícola y Pecuaria de Ybytymí (Paraguarí), que reúne a 205 familias, alertan sobre una plaga que afecta sus cultivos, amenaza la economía campesina y agrava sus deudas.

A new webpage by the Michigan Potato Industry Commission offers growers tools to identify and manage late blight, featuring pathogen details, outbreak protocols, fungicide advice and links to monitoring organizations.

Joseph Ifeanyi Ulasi leads a groundbreaking project to boost late blight resistance in diploid potatoes by introgressing novel Rpi genes from wild species. Using Solanum verrucosum as a genetic bridge, he advances resilient breeding for future crops.

Andy Diercks, a fourth-generation potato farmer from the small village of Coloma in central Wisconsin, is blunt about the difficult realities facing family-owned farms today.

Researchers at North Carolina State University identified the South American Andes as the origin of the Irish potato famine pathogen, Phytophthora infestans

Un nuevo sistema ha mejorado la conciencia de los productores sobre las condiciones que favorecen la enfermedad, reduciendo el uso de fungicidas y promoviendo prácticas agrícolas sostenibles.

The World Potato Congress has presented the upcoming webinar: Implementation of an Early Warning System for Sustainable Preventative Management of Potato Late Blight.

In an examination of the genetic material found in historic potato leaves, North Carolina State University researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.

El CIP ha obtenido resultados sobresaliente en el desarrollo de su variedad CIP-Matilde, resistente al tizón tardío gracias a los cruzamientos con variedades silvestres.

En la provincia de Junin, Perú, más de dos mil productores perdieron un total aproximado de 550 hectáreas. Las fuertes lluvias favorecieron el desarrollo de la plaga.

In 2014, Charlottetown-based research scientist Bourlaye Fofana was looking for a way to make plant products healthier by adding the antioxidant selenium.

The device has the potential to transform the way that farmers detect and manage plant diseases, leading to more efficient and sustainable agriculture practices.

Agriculture and Agri-Food Canada (AAFC) scientists have discovered that selenium, a micronutrient and anti-oxidant activates genes in potatoes that boosts the plant's immunity and helps in the prevention of late blight.

Tras pruebas en la Estación Experimental del IDIAP en Tierras Altas y fincas de productores colaboradores, hay resultados alentadores en el cultivo de papa.

Climate change is making it harder for farmers to grow enough food to feed their families. A new potato variety called CIP-Matilde, developed by the International Potato Center (CIP) with support from the Crop Trust.

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.

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.
