The population structure of fusarium pathogens of small grain cereals, their distribution and relationship of mycotoxins
Crop Types

University of ManitobaBackground
A better understanding of the factors responsible for the shift in Fusarium population and differences in trichothecene chemotype composition will enable the prediction of future population distribution, possibly related to future changes in climate. Fusarium chemotype diversity may be driven by differences in local selective pressures such as fungicide applications, agronomic practices, host specificity, crop sequence, and weather variables within a region. It may also provide opportunities to identify novel Fusarium populations and trichothecene chemotypes that may pose new threats to food and feed safety in Canada. Information from this study will be important in developing disease forecast models which enable growers to make economic decisions about FHB disease management strategies.
Objectives
- Evaluate Western Canadian population structure and chemotype dynamics of F. graminearum in cereals
- Prevalence, population structure and mycotoxins of F. poae affecting small grains in W. Canada will be studied.
