  • Mid-week mini cereal rust risk update – May 19, 2021

    There has been a significant increase in the number of wind trajectories, originating over a number of states in the USA, that have crossed the prairies (Fig. 1). These air currents may introduce cereal rust spores into to the Prairie region. ECCC trajectory models indicate that air trajectories, originating over the Pacific Northwest (Idaho, Oregon,…

    Since 2019, the Prairie Crop Disease Monitoring Network (PCDMN) has released a series of weekly Cereal Rust Risk Reports throughout May and June.  Read the OVERVIEW describing the collaborative nature of this effort and the methods employed.  Information related to trajectory events based on forecast and diagnostic wind fields and cereal rust risk is experimental,…

  • Scouting card for bacterial leaf streak of wheat

    Here is our latest edition to the Prairie Crop Disease Monitoring Network (PCDMN) suite of disease scouting cards.  Over the past 5-10 years there has been increasing observations of bacterial leaf streak (BLS) in wheat as well as bacterial issues in other cereal crops. Unfortunately in 2020 there were reports across the Prairie region, especially…

  • Ascochyta/mycosphaerella disease assessment protocols

    During June and July, crop scouting for the ascochyta/mycosphaerella complex in field pea is critical for assessing risk and gauging the need for and timing of an in-crop fungicide application.  However, late season crop scouting is also important as it can be used to assess the prevalence, severity and impact of these disease issues.  Where…

  • Blackleg of canola survey protocols and scouting information

    Blackleg is one of the key diseases faced by Prairie canola producers and has largely been kept in check with the use of resistant varieties and crop rotation.  However, over the past 10-20 years there have been concerns regarding observed shifts in blackleg pathogen virulence in response to the major gene resistance used in a…

  • Suggested protocols for assessing the incidence and severity of sclerotinia stem rot of canola

    During late June and July, crop scouting in canola is critical for assessing sclerotinia stem rot risk and gauging the need for and timing of an in-crop fungicide application.  However, late season crop scouting is also important as it can be used to assess the prevalence, severity and impact of this disease issue.  Where unsprayed…

  • Fusarium damaged kernel symptoms

    In-crop scouting at the late milk to early dough stage of development in your wheat and barley may indicate potential issues with fusarium head blight.  Make sure to follow up with an assessment of the harvested grain.  Here is an @PCDMN disease info card that outlines typical fusarium damaged kernel (FDK) symptoms as well as symptoms…

  • Developing a series of protocols for the practical surveillance of field crop diseases

    The Prairie Crop Development Network (PCDMN) is developing a series of recommended protocols for the practical surveillance of field crop diseases.    During June and July, crop scouting for various Prairie field crop diseases is critical for assessing risk and gauging the need for and timing of an in-crop fungicide application.  However, late season crop…
