La plaga afecta principalmente al Altiplano, lo que provoca la merma del 35% de producción por hectárea del tubérculo, según estudio hecho por el INIA.

The Plant Management Network provides information on how to improve efficacy of metam sodium application by shank injection in a new educational webcast developed by Neil C. Gudmestad

El Cabildo de Tenerife ha emprendido desde 2000 una cruzada contra una de las plagas habituales del campo tinerfeño: la polilla de la papa.

On the way from field to fork, more than half of the potato harvest is lost. This is according to a new study conducted by researchers from Agroscope and ETH Zürich.

Tecnoplant, la división de agrobiotecnología del Grupo Sidus, ha desarrollado cultivares de papa resistentes al ataque de virus que, en la Argentina, pueden provocar mermas de hasta un 70 por ciento en la producción.

The Dutch Association of Arable Farmers of (VTA) finds an average yield of 53.622 kg/ha, 8% below last year and on par with the 5-year average. Although tubers are large this season, the VTA predicts low factory yields as a result of a host of quality issues, resulting in an increased demand for potatoes per ton finished product.

Research shows that crops with stacks of two or more resistance genes from closely related species, introduced into the crop via for instance genetic engineering, combined with the simultaneous introduction of resistance management, can ensure the long-term resistance of these plants to economically significant and aggressive diseases.

The North-western European Potato Growers (NEPG) expect the total potato production (excluding seed and starch potatoes) of this year' s harvest to amount to 24.5 million tonnes. This is 14.1 percent below the potato production last year and 2.9 percent below the 5-year average.

El cultivo de papa presenta varias afectaciones que producen perdidas y malestar en los productores; el gusano jiguá, la chiza y algunas clases de polilla. Las heladas en época de invierno también afectan gravemente los cultivos

The J.R. Simplot Company is pleased that the USDA has deregulated the Russet Burbank variety of the second generation of Innate™ potatoes. Simplot is looking forward to the completion of the EPA registration and FDA consultation before the second generation of Innate™ potatoes can be introduced into the marketplace.

In the annual VTA sampling of the development of the Dutch potato crop development, mid August a yield was found 16% lower than last year and 7.1 below the 5 year average.

A new 'Focus on Potato' webcast titled “Managing Diseases with Biopesticides in Potato Production” helps growers, consultants, and other practitioners in the potato industry understand the basics of biopesticides and their use in the field.

Scientific results of the potato field trials in Flanders and the Netherlands demonstrate that gene stacking is necessary for a strong and lasting resistance to late blight (Phytophthora infestans).

Late blight has become widespread in Idaho and is called the worst Idaho late blight outbreak since 1998.

The latest Focus on Potato webcast, titled “Best Management Tactics and Fungicide Resistance in Early Blight and Brown Spot” highlights the importance of measures to mitigate fungicide resistance, particularly when applied and repeatedly used on a single site.

The National Potato Council awards its 2015-16 Academic Scholarship to Shunping Ding, a PhD. student in Plant Pathology at the University of Wisconsin-Madison.

Investigadores del Instituto de Ecología (INECOL) logran disminuir con un plaguicida denominado bionematicida un gusano llamado nematodo dorado, el cual es responsable de la baja producción de papa en México.

Australian horticulture researcher and industry stalwart Dr Kevin Clayton-Greene has been honoured with a prestigious Industry Recognition Award at the 9th World Potato Congress in Beijing, China.
