Texas: Neonicotinoid insecticides losing efficiency in potato psyllid control

The Texas potato industry may be losing a mainstay in the battle against psyllids, according to a recent Texas A&M AgriLife Research study. Dr. Ada Szczepaniec, AgriLife Research entomologist in Amarillo, said while there may be varying degrees of resistance to neonicotinoid insecticides in populations of psyllids across Texas, her recent study indicates they’ve lost their punch. “We are able to provide strong evidence that these insecticides no longer suppress populations of…

Guarding Against Dickeya

After triggering major crop losses in the United States, Dickeya has been dominating the potato meetings circuit in North America for the past year or two. In Canada, some of the discussions revolve around the consequences for growers should the new disease makes its way into this country — but some industry experts maintain Dickeya is likely already here. “I don’t know what the extent is [in Canada], but we found Dickeya…

IPM Training Module Launched

Positive comments are coming fast and furious for a new potato integrated pest management (IPM) training module recently launched by the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA). According to OMAFRA, “the module is a great educational tool with information for the common insect pests, diseases, viruses and disorders of potatoes in Ontario.” The creator of the module is Eugenia Banks, OMAFRA’s longtime potato specialist who retired in late 2015….

Fast-Tracking Extreme Resistance

A key tool in the arsenal for controlling potato virus Y (PVY) is cultivar resistance. Now, researchers are developing better molecular markers for faster, more accurate screening of potato breeding lines for “extreme resistance” to PVY – equivalent to PVY immunity. That will enable breeders to more efficiently develop new varieties with total protection against this serious disease. “PVY is one of the most widespread viruses and also one of the most…

Managing Soil-Borne Pests, Diseases

For potato farmers, soil-borne pests and diseases are like that pesky younger sibling that’s always trying to get you in trouble: ignore them at your peril. Hazards such as Verticillium, nematodes, pink rot and Rhizoctonia can have a big impact on the bottom line if not kept in check. For this edition of Roundtable, Spud Smart sought input from three industry experts on the financial importance of these potato problems, and best…

Improving Soil, Improving Potatoes

Innovative growers and an agronomist recently teamed up to look at ways to improve the potato crop and the soil. For three years, Bruce and Hunter Wilson gave agronomist John Lightle the go ahead to try some cover crop combinations on their 6,000 acre farm in the Dufferin Highlands of Ontario. The acres are in a prime potato producing area and the growers wanted to maximize their yield while considering other cropping…

Conservation Measures Outperform Conventional Yields

Conventional potato production appears ultimately to produce the highest net return per acre. But you have to weigh that against “conservation” potato production practices that not only grow potatoes, but also do more to improve overall soil quality and health. What is that worth to a producer? That conclusion comes following a 12-year Agriculture and Agri-Food Canada (AAFC) field study comparing conventional irrigated potato production practices and conservation practices that included no…

Convincing the Unconvinced on Precision Agriculture

Precision agriculture is cutting edge, high-tech and full of potential. At least some western Canadian potato farmers, however, see it as overwhelming, costly, frustrating, and/or difficult to implement. If you look past the hype and excitement surrounding precision agriculture, you’ll find a group of farmers who have tried it and quit, or who were turned off the concept before they ever started. Jeff Bronsch, an agronomic consultant in Taber, Alta., understands farmers…

Sorghum-Sudangrass as Rotation Crop

The ideal potato rotation crop is one that offers more than one agronomic benefit and also has a positive effect on potato yields. An exciting rotation option with great potential on both these fronts is now being investigated in a second in-depth study in P.E.I. Sorghum-sudangrass is being closely examined as part of a larger cross-country study focused on enhancing the productivity and sustainability of Canadian potato production. The national team includes…

Red-skinned potato varieties lead selections by breeders

Red-skinned potato varieties made up half of the total selections Agriculture and Agri-Food Canada (AAFC) breeders released to industry during the annual potato selection release open house on Feb. 15. For the first time, the program will unveil a multi-purpose red-skinned selection, showing promise for processing as wedges and as a traditional table potato. In all, 15 selections were displayed this year by the AAFC breeding program for industry representatives in Fredericton,…
