A two-year project funded through the University of Wisconsin-Water Resources Institute is investigating an interseeding cultivation method for potato cropping that shows early promise to reduce nitrate leaching. Researcher Kevin Masarik from UW-Stevens Point is pursuing what he termed an outside-the-box idea – interseeding rye, oat and millet between the rows of potatoes to create biomass to take up excess nitrates.
AHDB’s Fight Against Blight programme started in 2004 and since then ‘blight scouts’ have sent in over 10,000 samples of potentially blight infested potato plants for genotyping. Each year the results are published because knowing the location of outbreaks and the dominant genotypes, allows for better prevention of the disease. This has been particularly valuable when genotypes behave differently to the norm, for example if they are insensitive to a certain treatment, or if they aggressively reproduce more quickly than typical spray cycles.
Dr. Michele Konschuh, a research associate in the Department of Biological Sciences at the University of Lethbridge in Canada’s Alberta province, is leading a study to help ensure Alberta’s potato industry stays healthy. Blackleg is caused by Pectobacterium and Dickeya bacteria. Of the two, Dickeya is especially aggressive. “The one we have in Alberta is caused by Pectobacterium species. At this time, we have no Dickeya and we want to keep it that way,” says Konschuh.
The European Potato Trade Association (Europatat) is part of an international consortium involved in the research project ADAPT (“Accelerated Development of multiple-stress tolerAnt PoTato”). The project aims to develop new strategies to make potatoes fit for the challenging climatic growth conditions expected in future.
Plant scientists at the James Hutton Institute are studying the evolution of late blight in potato by working with industry and research partners to track the distribution and diversity of dominant clones in Europe in 2020, and have also contributed to a review into the development of the disease in Asia in the last 150 years, as part of global efforts to improve the sustainable production of healthy potato crops.
For the sake of the health of conference participants and in consideration of the dynamically changing realities related to the COVID 19 pandemic, EAPR President Jadwiga Śliwka and the organizers have announced today that they have decided to postpone the 21st EAPR Triennial Conference. The new conference dates are now 4-8 July 2022. The Conference will be held in the International Exhibition and Convention Centre EXPO Kraków, former capital of Poland.
A recently published article by academic experts Marc Ghislain, Rick Goodman and Alex Barekye describes the development of an African potato variety – transformed with three resistance genes from wild potato relatives – that provides resistance to late blight disease. The article was published by OpenAccessGovernment.
Agriculture and Agri-Food Canada (AAFC) researchers are encouraging farmers to buck the trend and use buckwheat as a triple threat crop. In addition to its high nutritional value, the fast growing crop is proving to be beneficial in suppressing pests such as wireworms in potatoes, and preventing soil diseases.
This is a condensed version of a more thorough and detailed analysis, involving over a dozen sites between 2019 and 2020. Sites included irrigated low organic matter sands and sandy loam soils in central Minnesota. The study was done by Anez Consulting, based in Little Falls and Paynesville, MN. The article below was authored by Precision Agronomist, Michael Dunn.
A team of scientists led by Nanyang Technological University in Singapore (NTU Singapore) has developed a device that can deliver electrical signals to and from plants, opening the door to new technologies that make use of plants. The NTU team developed their plant ‘communication’ device by attaching a conformable electrode (a piece of conductive material) on the surface of a Venus flytrap plant using a soft and sticky adhesive known as hydrogel. The NTU team is looking to devise other applications using an improved version of their plant ‘communication’ device.
A pernicious agricultural pest owes some of its success to a gene pilfered from its plant host millions of years ago. The research finding is the first known example of a natural gene transfer from a plant to an insect. It also explains one reason why the sweet potato whitefly Bemisia tabaci is so adept at munching on crops: the gene that it swiped from plants long ago enables it to neutralize a toxin that some plants produce to defend against insects.
The final loss of approval of Vydate in the UK on 31 December brings an Innovative Farmers field lab into sharp focus as many potato farmers search for alternatives to control potato cyst nematode (PCN). Farmers in Shropshire and Lancashire further investigate the efficacy of growing trap crops to control the nematode.
Canadian researchers pursue anti-virulence strategy in fight against common scab, antibiotic resistant bacteria
In the ongoing war against antibiotic resistant bacteria, a change in battle tactics may prove effective for controlling common scab of potatoes and potentially other toxins that affect humans and animals, according to Canadian Light Source Inc. The approach that Dr. Rod Merrill at the University of Guelph and his research group are pursuing is an anti-virulence strategy – finding or designing small molecules that inhibit the tools bacteria use to colonize the host and create infection.
There is generally pressure for potato store managers to closely monitor carbon dioxide (CO2) levels in the industry. However, this management tends to be met with mixed views. Storage experts at AHDB’s Sutton Bridge Crop Storage Research in the UK are looking to settle the debate in an ongoing storage trial.
The Idaho Global Entrepreneurial Mission (IGEM) program has spurred many agricultural innovations that promise to help the Gem State’s farmers and ranchers improve their bottom lines. IGEM projects are now helping the state’s potato industry remove harmful pathogens in storage and to better scout fields for a disease that’s especially problematic for seed growers, potato virus Y. A third project aims to help the chipping industry reduce levels of acrylamide.
The future of potato breeding? UMaine professors trying to develop potato varieties using new DNA-based tools
Two professors at the University of Maine in Orono are working on breeding new potato varieties. Hannah Yechivi reports for News Center Maine that professor of crop ecology and management in the School of Food and Agriculture, Dr. Greg Porter, and assistant professor of plant genetics with the School of Biology and Ecology Dr. Han Tan are studying how to make more varieties using a new DNA-based tool.
Since 2018, HZPC and Averis Seeds have been collaborating in the “Flight to Vitality” research project. It is a quest for the factors that influence the germination capacity – and therefore the vitality – of seed potatoes. At the end of 2021, when the practical investigation is completed, the company says it is hoping that the mystery will be solved. The answer to one question has always remained unanswered: how is it possible that seed potatoes sometimes grow much better and faster than at other times?
Researchers Sanjoy Guha Roy, Tanmoy Dey, David E. L. Cooke and Louise R. Cooke recently published this review in the journal Plant Pathology. In a news article for the The British Society for Plant Pathology (BSPP) the research team writes they have scoured the literature to report on the dynamics of Phytophthora infestans (1870-2020) that has shadowed the expansion of potato cropping.
Breakthrough research: Wastewater from potato processing plants could be used in the recycling of high-tech devices
Every year, it takes millions of gallons of water to clean, peel and slice Idaho’s potatoes before they’re processed into any number of products from tater tots and animal feed to industrial starch. As a result, Idaho potato processors must treat and dispose of a large amount of wastewater that contains organic matter, silt and sand. But now, new research from Idaho National Laboratory suggests that potato wastewater might serve well as a low-cost food source for a special bacterium that could be used to recycle high-tech devices.
AHDB Potatoes announced today that L P Ollier & Son, Knutsford, has agreed to host a number of field experiments as part of the 2021 Strategic Potato Farm programme.
