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":""}]
