An environmentally friendly solution to potato early dying complex

Agriculture and Agri-Food Canada (AAFC) researchers in Fredericton are exploring environmentally friendly solutions to manage Potato Early Dying complex (PED), a disease that is limiting yields in many potato fields in Eastern Canada. PED is a disease complex caused by a combination of a fungal disease (Verticillium wilt) and root-lesion nematodes. With few available treatments, a process called biofumigation is being used by some growers to manage PED.  The process involves tilling…

GMO potato can reduce fungicide use by 90 per cent

Researchers in Ireland and the Netherlands have discovered that a genetically engineered potato carrying a blight resistance gene could help farmers reduce fungicide sprays by up to 90 percent. Scientists from Wageningen University in the Netherlands and Teagasc, the Irish agricultural research agency, conducted three years of field tests in the two countries to examine the effectiveness of potato genes aiming to confer resistance to Phytophthora infestans, otherwise known as late blight…

Colorado Potato Beetles Wanted

Dr. Ian Scott, a research scientist with the London Research and Development Centre at Agriculture and Agri-Food Canada, is conducting a survey of Colorado potato beetle susceptibility levels to registered insecticides (neonicotinoids, diamides and spinosyns). What does he need? He is looking for approximately 150 beetle adults (a minimum of 75 adults or large larvae are acceptable) per sample. If you have a few you can spare, please contact Dr. Scott and…

Comparing New Nitrogen Alternatives

Nitrogen use efficiency is a topic that is an intersection of food security, environmental sustainability and economics in our agricultural production systems. We need to use nitrogen to produce a good harvest. So says Dr. Guillermo Hernandez Ramirez, the study’s lead investigator and an assistant professor in the Department of Renewable Resources at the University of Alberta. “However, by using nitrogen fertilizer we also have the risk of losing some of that…

Wild potatoes from Germany breed stronger, more disease resistant potatoes

Wild potatoes acquired from a gene bank in Germany six years ago are producing promising results for Agriculture and Agri-Food Canada researchers trying to develop superior Canadian varieties with resistance to some of the most problematic potato diseases. 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…

Boosting soil carbon, boosting potato yields

Louis-Pierre Comeau is adding the soil carbon piece to Agriculture and Agri-Food Canada’s (AAFC) research efforts in the Maritimes. His studies will be contributing to the development of practical, profitable agricultural practices that increase soil organic matter for improved potato yields. Carbon is part of all plants and animals, and the key element in soil organic matter. “In turn, soil organic matter is essential for a variety of needs like food, fibre…

NSERC funds UPEI research into potato input technologies

The development of new technologies and systems for the application of potato production inputs has received a funding boost at the University of Prince Edward Island (UPEI). The National Science and Engineering Research Council of Canada (NSERC) has awarded Dr. Aitazaz Farooque, an assistant professor at UPEI’s School of Sustainable Design Engineering a Discovery Grant and Discovery Accelerator Supplement. Farooque’s research — Development of Precision Agriculture Technologies to Improve Crop Productivity and…

Farming From Space

Technology in all areas of farming continues to evolve, and satellite data collection and analysis is no exception. It’s becoming less expensive every year to collect data on crops, weather and more from space, and the information gathered is also getting much more detailed and reliable. Satellite data are useful to the agriculture community not only in terms of understanding long-term trends, but in gaining faster and better insight into crop-soil health…

Preparing for the Potato’s Future

It’s always been critical to breed new crop varieties with good yield and harvest quality, but it’s more important than ever to do so now, with crops facing myriad stresses related to changing climate conditions. Dr. Keshav Dahal, a crop stress physiologist who joined Agriculture and Agri-Food Canada’s Research and Development Centre in Fredericton, N.B. during summer 2017, is helping unlock how some plants sense and react to stress more effectively than…

From muddy spud to the perfect French fry: Information experts are optimizing potato production

Modern potato harvesting can be a pretty rough business. In years gone by, the farmers would be out in the fields assisted by friends and family carefully digging up the potato crop by hand. Today, mechanical harvesters are in use. But if the machinery is not adjusted correctly, the potatoes can get badly bumped and knocked as they move along the agitator belts, hitting stones and each other on their way. This…
