Aphanomyces Test in Soil and Tissue

Aphanomyces euteiches is a destructive root rot disease of peas,lentils, alfalfa, and native legumes worldwide. It is a very persistent water mold that lives in wet or flooded areas, the spores of which can remain viable in the soil for up to 10 years. There has been an increase in the number of confirmed cases in both Saskatchewan and Alberta since it was first discovered in 2013.  Lentils and peas are the most susceptible crops and risk factors include close rotations of susceptible crops, soil moisture and compaction. Scout for symptoms in low lying areas that are prone to water-logging and test your soil to determine if the pathogen is present. Information about Aphanomyces can be found through provincial pulse commissions or government pulse crop specialists.  Read our Technical Bulletin to learn about this new disease and how we can help you confirm disease presence. Three additional Aphanomyces resources are listed below: 1. ‘Root Rot in Western Canada’. ...

BioVision Seed Labs: Fusarium graminearum in wheat and barley

Fusarium graminearum testing of wheat and barley seed is a critical step in best management practices, and is required under the Alberta Pest Control Act prior to the sale/sowing of seed. This pathogen is closely monitored by the grain, malt and livestock industries, as it produces vomitoxin (DON) in cereal grains. Two detection methods are available at BioVision: Plated and DNA.

Read specific details about the test methods available for Fusarium.
