The population structure of Fusarium pathogens of small grain cereals, their distribution and relationship to mycotoxins

Fusarium head blight (FHB) is a fungal disease affecting cereal crops in Canada that reduces productivity and produces mycotoxins in the grain. This fungal disease is caused by a number of Fusarium species. In Canada, Fusarium graminearum is considered as the most important Fusarium species because of its abundance, its toxin producing ability and its impact on grain quality and yield.

Glyphosate- or Auxinic-Resistant Kochia and Russian Thistle Prairie Surveys

The objective of this project is to determine the evolution or spread of glyphosate-resistant (GR) or auxinic-resistant kochia in Manitoba in 2018, Saskatchewan in 2019, and Alberta in 2021 since the 2012/2013 baseline surveys. In the 2012/2013 surveys, GR kochia was found in 5% of randomly-surveyed sites in Alberta and Saskatchewan (annually-cropped fields and non-crop areas such as oil well sites, railway rights-of-way, and roadside ditches), but only two sites in Manitoba.

Economic Value of Diversified Cropping Systems

Short crop rotations provide an environment conducive for an increase in plant disease, weed pressure from herbicide resistance, and insect damage (these productivity decreasing factors will be referred to as “pests” in this document). While some short rotations are currently profitable, the lack of diversification in a cropping system can be detrimental to maintaining crop yield and profitability. Factors that contribute to the profitability of cropping systems will identify why the seeded area of some crops is declining while increasing for others.
