Stronger potato varieties will increase yields for Canadian growers, which translates into higher profits.
Dr. Benoit Bizimungu, head of potato breeding at the Fredericton Research and Development Centre, said a number of hybrids bred from these wild varieties could be ready for industry trials next year.
Bizimungu selected the German plants because of superior traits such as high yield, as well as strong natural resistance to PVY, late blight, drought, and insects like the Colorado potato beetle.
“Although the primary interest was multiple disease resistance and high yield potential, a number of progenies show a nice deep yellow flesh color, which is usually associated with carotenoids,” Bizimungu explains. This is great news for consumers who want more antioxidants in their diet.
“What is really exciting is that some of these wild species have never been used in potato breeding before now,” he says. “Using these new parents broadens the genetic base.”
“It’s good to have multiple sources for breeding, especially for things like late blight where it keeps changing.”
Dr. Bizimungu obtained this unique plant material as a result of his collaboration with potato geneticist Dr. Ramona Thieme of the Julius Kuhn-lnstitut (JKI) at the Federal Research Centre for Cultivated Plants in Braunschweig, Germany.
The imported species come from wild potato cultivars that originated in South America, the birthplace of the potato.
Robert Anderson and Jill Ebbett, fifth-generation potato farmers from East Glassville, N.B., were named Atlantic’s Outstanding Young Farmers for 2018.
Agriculture and Agri-Food Canada scientist Louis-Pierre Comeau is sifting his way through New Brunswick soil in search of answers to one of the biggest issues facing local farmers: the loss of soil organic matter and the decrease of soil health in farm fields.
This project, supported with a federal government investment of up to $4.5 million, includes the purchase and installation of new robotic equipment that will sort, grade, and pack more fresh potatoes in less time, enabling the company to improve their product quality, lower operational costs and develop new markets in the United States.
The company specializes in potato packaging and employs more than 125 people. The new plant is intended to give Patates Dolbec more flexibility and allows the company to track data in real-time for better decision making and a more organized workplace.
Syngenta Canada Inc. has received registration for Revus fungicide as a potato seed treatment for the suppression of pink rot and control of seed‑borne late blight in potatoes.
Pink rot is a devastating, soil-borne disease caused by the pathogen Phytophthora erythroseptica that thrives in wet, poorly drained soils. Infection typically takes place pre-harvest, as the pathogen enters tubers through the stem end and lenticels.
Tubers infected with pink rot will often decay during harvest and handling, which allows the pathogen to spread quickly from infected tubers to healthy tubers while in storage.
“Every field has the potential for pink rot,” says Brady Code, eastern technical lead with Syngenta Canada. “It takes a very small number of infected tubers going over harvest equipment or getting by on the belt to put an entire season of work in jeopardy, and leave growers with far fewer healthy potatoes to ship.”
Revus contains the active ingredient mandipropamid (Group 40), and works by protecting the daughter tubers from becoming infected with pink rot. It also provides control of seed-borne late blight (Phytophthora infestans), according to a company press release.
Revus is applied at 5.9-11.8 mL per cwt of seed (13-26 mL/100 kg of seed).
Following a seed treatment application of Revus fungicide, the first foliar fungicide application should be a product that does not contain a Group 40 active ingredient.
Maximum Residue Limits (MRLs) for mandipropamid have been established for markets including Canada, the United States, Japan, and South Korea, in support of the seed treatment use pattern.
