Clearfield Confirm Bioassay Technical Bulletin

Clearfield Confirm is a herbicide bioassay test designed to measure the tolerance of a submitted sample to an imidazolinone herbicide treatment (ie: imazamox) using a seed based germination assay. Herbicide-tolerant Clearfield® varieties are those capable of producing normal seedlings in the presence of the herbicide. Clearfield®  wheat and lentil varieties are both tested by BioVision, although the methods differ slightly for each crop kind.

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’. ...

Soil Seed Analysis - Key for land reclamation activity

Weed populations are established each year because of persistent seedbanks in arable soils. A knowledge of weed seedbanks is necessary, for example, to carry out studies of population dynamics, to establish weed management programs, or to avoid weed spread when transferring potentially contaminated soil.

Cool Stress Test - The premium vigor test for your seed

BioVision Seed Labs conducts cool stress testing on most seed crops grown in Canada. By introducing cool chamber temperature, the seedlings will respond based on numerous factors either genetic or induced by in-crop growing conditions. The crop species tested will determine the growing media, growth chamber temperatures and photoperiod.

Learn about the method we use for cool stress testing and how it stacks up against the germination test.
