Growers should scout their fields for symptoms of early infections on cotyledon leaves starting two weeks after planting. These lesions may be irregular in shape and have a light brown color. Numerous pycnidia which look like tiny grain of black pepper may be produced in the dead tissues especially if humid conditions prevail for several days. For symptoms illustrations, see the Diseases section of this app.\r\n\r\nAs the plants continue developing, symptoms on true leaves may also appear. Their presence in plants with less than four true leaves is an indication that blackleg may be a problem that requires fungicide applications. A list of foliar fungicides registered for use in canola against blackleg can be found in the Diseases section of this app under blackleg.\r\n","poster":"Luis del Rio","time":"2020-05-17 14:24:41","link_desc":"","link":""},{"_id":"55","title":"New Teaching Video Illustrates Life Cycles of Blackleg and White Mold on Oilseed Rape","Body":"Global demand for oilseed rape is on the rise, especially in countries such as China and India, where growing populations and economies require greater yields. However, oilseed rape production faces many challenges, including the major fungal diseases blackleg (stem canker) and white mold. Both diseases can cause substantial losses of yield and quality.\r\n\r\nA new teaching video, Blackleg and White Mold: Two Major Fungal Disease of Oilseed Rape, Vol. 1 of Diseases and Pests of Rapeseed, uses stunning computer animation blended with real-life video to illustrate the life cycles of the blackleg and the white mold pathogens. This 12-minute video clearly presents the development and epidemiological spread of these diseases, along with measures to control them. \r\n","poster":"Kishore Chittem","time":"2019-04-20 11:06:45","link_desc":"Perfect for students and extension audiences, Blackleg and White Mold: Two Major Fungal Disease of Oilseed Rape, is available in the APS PRESS bookstore.","link":"http:\/\/my.apsnet.org\/ItemDetail?iProductCode=46161"},{"_id":"52","title":"Blackleg label for canola hybrids coming soon ","Body":"Starting with the 2019 growing season, the canola seed industry in Canada will disclose the major blackleg-resistance genes present in their hybrids using a labeling system.

For the most part, those fields should not be affected by Sclerotinia anymore. Fields planted between the 25 and the end of May should be between early flowering and late flowering. Fields that are past the full bloom stage have relatively low risk of being affected by Sclerotinia even if the environment is conducive for infection. It is important to keep in mind that field trials have shown fungicide applications made past the full bloom stage typically do not provide economic returns.","poster":"Luis del Rio","time":"2017-07-19 16:47:20","link_desc":"","link":""},{"_id":"45","title":"Blackleg prevalence in Cavalier County is high","Body":"A survey of 26 canola fields in Cavalier County revealed that blackleg continues to be the most prevalent disease in the county. All but three of the 26 fields surveyed (88%) had blackleg symptomatic plants on them. In almost one of every six fields surveyed blackleg incidences were greater than 30%. It is very likely fields with such high incidences will experience economic yield reductions. Growers should remember that fungicide applications for control of blackleg should be made when plants are between 2-4 leaf stage. Applications at later times usually do not provide economic returns.","poster":"Luis del Rio","time":"2017-07-19 16:46:37","link_desc":"","link":""},{"_id":"39","title":"Reading Sclerotinia Risk Maps","Body":"The risk map will be available this year starting on June 18th. Maps showing the estimated risk of development of Sclerotinia stem rot on canola will be produced daily for the duration of the flowering period. When reading the maps growers should be aware that the estimated risk applies only to canola crops that are entering the flowering period or are already flowering. This risk is calculated considering the effect of environmental factors. A risk calculator that combines the effect of weather variables, cultural practices, and history of Sclerotinia is also available. While this information is intended to advise growers when conditions may be favorable for disease development, the final decision on whether to spray a fungicide or not should include economic considerations such as the potential yield of the field and the potential market price for the commodity.","poster":"Luis del Rio","time":"2017-06-27 01:53:02","link_desc":"","link":""}]
