马铃薯Y病毒（PVY）

Ongoing studies at the University of Idaho’s Aberdeen Research & Extension Center seek to help seed potato growers avoid a chronically troublesome disease spread by aphids, called potato virus Y, writes John O’Connell in the Idaho State Journal.

Aphids and the plant viruses they transmit cause billions of dollars in crop damage around the world every year.

El evento transgénico, desarrollado por investigadores del CONICET y la empresa Tecnoplant, ya obtuvo todos permisos necesarios para su comercialización en el pais.

After 20 years of biotechnological research, the first GM potato that is resistant to the PVY virus will go on sale next year in Argentina

Después de 20 años de investigaciones, esta variedad saldrá a la venta el año que viene, con beneficios productivos y económicos estimados en 45 millones de dólares por año, sólo en el mercado argentino.

The scale of the Potato Mop-Top Virus problem on New Zealand South Island potato farms has widened. Eighteen Canterbury farms are now on the suspect list, after the virus was first confirmed on two properties last month.

Biosecurity New Zealand is working with Potatoes New Zealand to respond to a detection of Potato mop-top virus (PMTV) in potato tubers in Canterbury. Though common around the world, it is the first time the virus has been found in New Zealand.

Farmers, researchers and members of the public gathered at the University of Maine’s Aroostook Research Farm in Presque Isle last Wednesday to learn about the latest in potato research.

Based on extensive trials (two years, three separate farms, ten potato varieties) in a joint effort of AHDB, James Hutton Ltd, SASA and Seeds2B Africa (part of the Syngenta Foundation) three GB potato varieties have been recommended for release in Kenya.

Farmers in India can expect higher yields and profits with the release of a new potato variety, Kufri Lima, developed by the International Potato Center (CIP) and the Central Potato Research Institute (CPRI)

Two recently released new Russet varieties - Castle Russet and Echo Russet - should help the potato industry in the Pacific Northwest cope with more stringent regulations on soil fumigants

Seed potato growers on Kangaroo Island - an island off the mainland of South Australia - are successfully adopting a new strategy to manage the aphids and thrips pestering their crops, taking on expert advice from agronomists and entomologists to adopt integrated pest management for these insect pests.

Esta nota analiza el problema de la degeneración de la semilla, detalla la estrategia propuesta del Programa del CGIAR de Raíces, Tubérculos y Banano, y describe cinco técnicas sencillas para mejorar la calidad de la semilla y aumentar la producción de papa.

El Dr. Luis Salazar visitó el país invitado por el Consorcio Papa Chile. Su visión de la situación actual de la papa frente a los virus que le atacan; las debilidades y fortalezas del rubro en Chile, y sus consejos, en esta entrevista exclusiva.

Several newly evolved strains of the disease known as potato virus Y, or PVY, can render potatoes unmarketable and reduce crop yield. What’s worse is the new viruses are particularly difficult to detect with the naked eye.

With pesticide resistance rising in species of aphids which feed on potatoes and spread viruses, one of the best control options for growers battling these pests may be found in nature, free of charge: parasitic wasps.

Potato tubers are affected by a number of blemishes, which can cause severe economic losses. This 'Focus on Potato' presentation by Jacquie van der Waals, Professor at the University of Pretoria in South Africa can serve as a guide for growers and others in the potato industry to help with identification of these blemishes.

Idaho State University researchers have found high-tech cameras mounted on drones flying 60 meters above potato fields can effectively detect individual diseased and stressed plants.
