Disease Survey Time is Approaching Quickly!

Every year disease surveys occur, not only Manitoba, but across Canada and other countries around the world.  So why conduct these surveys?  Disease surveys are an important component of integrated disease management plans.  The surveys can give an indication of potential problems if disease levels are high, if there are changes in pathogen types or races occurring, supply information that can be used in the future for monitoring and control measures, and provide historical information on the occurrence and severity of disease in Manitoba and the assessment of losses from disease.

The CANADIAN PHYTOPATHOLOGICAL SOCIETY (CPS) publishes their annual CANADIAN PLANT DISEASE SURVEY, available on the website at http://phytopath.ca/publication/cpds/. It is a periodical of information and record on the occurrence and severity of plant diseases in Canada and the estimated losses from diseases. For Manitoba, historical information is provided for various diseases and crop types, such as in cereals Fusarium Head Blight, smut, stem rust, leaf rust, stripe rust, crown rust, and in canola sclerotinia stem rot, blackleg, aster yellows and clubroot.  Information for other crop types are also available, including field beans, flax, peas, soybeans, corn and sunflowers.

Biosecurity.  Surveys also play a role in crop biosecurity and plant health. An important part of minimizing or preventing the spread of pests is early detection through timely scouting, monitoring, assessment and decision-making.  A strong information network that is often created through surveys and its reporting provides for resources in assessing new problems and alerting others about potential risks.

So if you are a producer and someone asks if they can include your field in an annual disease survey, consider saying yes!
