Economize on fungicide through rapid detection of sclerotinia

Key Result: Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is commonly managed by routine application of fungicides, typically without any indication of disease risk. Through this study, a quantitative polymerase chain reaction (qPCR)-based assay was developed to measure S. sclerotiorum DNA in canola petals, enabling rapid and accurate estimates of infestation levels when timely fungicide...

Aster yellows: Seed treatment benefit; rating damage

Key result: The study found that seed treatment can reduce leafhopper feeding and therefore suppress aster yellows (AY). It also produced a five-point rating scale to score canola plants for AY damage and help predict yield loss. Project title, Principal investigators: “Seed treatments as an alternative method of controlling leafhoppers and aster yellows disease in...

Identifying and controlling cutworms

During cutworm outbreaks, accurate and rapid identification is required to maximize control methods.
Key result: A pest complex of economically significant cutworm species can be found on the Prairies, and outbreaks seem to be occurring with greater frequency. This study has resulted in a DNA protocol for quick, accurate identification of cutworm species; identification of natural enemies and evaluation of their ability to develop on different cutworm species;...

Consider seed size when targeting optimum plant stand

Key result: Seeding rates should be established based on 1,000-seed weight, using an on-line seeding rate calculator or on-line apps. Project title, Principal investigator: “Seed size and seeding rate effects on canola yield and quality,” Neil Harker, Agriculture and Agri-Food Canada Lacombe Funding: Alberta Canola, MCGA, SaskCanola, CCC, AAFC, GF2 Recent surveys indicate that approximately...
