There are additional benefits of farmers applying this solution. They can spray their crops in the field or greenhouse with the recommended dose of selenium and that will help the plant to boost its immunity against late blight."ĭr. Fofana recommends applying selenium to crops when there is no rain in the forecast for one to two days to ensure maximum effectiveness against preventing late blight disease. "Farmers can use this selenium solution as a preventative measure like they would with a pesticide or herbicide. Due to the risk of the disease spreading, Dr. Fofana could not test this in an outdoor field setting but is confident that the results could be similarily positive for farmers looking to successfully prevent late blight disease in their crops. The results in a controlled greenhouse environment and the lab are remarkable. They got the same results at AAFC's Charlottetown Research and Development Centre laboratory where selenium stalled the growth of late blight in test tubes. The first spray of selenium solution caused the plant to ready itself to defend against disease and the second spray actually prevented late blight from growing in the potatoes. What they discovered is significant for farmers. Following the application of selenium, they injected the plants with late blight disease and then sprayed the plants again with selenium. They developed liquid solutions containing various concentrations of selenium and sprayed them onto the leaves of potato plants in the greenhouse at the Harrington Research Farm on PEI. Dr. Bourlaye Fofana, Research Scientist, Agriculture and Agri-Food Canadaĭr. Fofana and AAFC plant pathologist, Dr. Rick Peters, set out to find an answer to this question. I knew that it was possible to increase the health benefit of plants with selenium, but as an antioxidant, can it to boost plant immunity against diseases?" "Selenium is also an antioxidant, similar to blueberries, which helps reduce the risk of many diseases. Selenium is essential to the diets of humans and animals and plays a key role in our metabolism. In 2014, Dr. Fofana studied how selenium, a micronutrient or mineral that is found in soil, water and some foods, can be boosted in foods such as potatoes, soybean and flax. However, his previous research of improving human nutrition through plant products laid the foundation for an important discovery for preventing late blight in potatoes. Most recently he has identified several genes in potatoes that are resistant to another serious disease, common scab. Dr. Bourlaye Fofana is a geneticist with AAFC in Charlottetown, Prince Edward Island (PEI). This leaves farmers with lost profits as the crop cannot be sold to consumers.Īgriculture and Agri-Food Canada (AAFC) scientists have been studying this disease for many years to ensure that Canada doesn't fall victim to the destruction that late blight had in Europe centuries ago. If the disease cannot be contained, farmers may be required to destroy an entire field as a last resort. Once late blight is found in a farmer's field, that area must be destroyed along with its crops to prevent the threat of the disease spreading. Left untreated, the disease can cause widespread damage. The culprit was late blight disease - a fast spreading disease that causes mold symptoms on potato and tomato crops. Agriculture and Agri-Food potato famine in the 1840s was devastating to potato farmers and caused widespread hunger across the continent.
