Crop Protection Projects

Diseases, insects, and weeds all pose threats that can rob yield directly from the field and negatively impact grower profitability. It’s important to develop accurate disease and insect forecasts and make the best practical information available to growers.

Projects underway

Facilitating the delivery of practical sclerotinia stem rot risk forecasts based on improved assessment of canola petal infestation
Weather-based assessment of sclerotinia stem rot risk
Defining populations of the L. maculans pathogen in test sites used for canola blackleg resistance trials
Mitigation of risk to canola from spring flea beetle injury

Facilitating the delivery of practical sclerotinia stem rot risk forecasts based on improved assessment of canola petal infestation

(SC 3.3.1)
Objective: To develop a rapid method of pathogen detection on flower petals and relate this to field incidence of sclerotinia and weather/crop modelling. To collaborate with private seed testing labs with Polymerase Chain Reaction (PCR) capabilities, universities, industry and provincial staff to deploy a commercially available test related to sclerotinia stem rot risk forecasts.

Research team: Dr. Kelly Turkington (AAFC, Lacombe) – Principal Investigator; Dr. Stephen Strelkov (University of Alberta); Dr. Gary Peng (AAFC, Melfort); Dr. Bruce Gossen (AAFC, Saskatoon); Dr. Debbie McLaren (AAFC, Brandon); Dr. Khalid Rashid (AAFC, Morden); Dr. Faye Dokken (SAF, Regina); Dr. David Kaminski (MAFRI, Carman); Dr. Jim Broatch (AARD, Lacombe); Derwyn Hammond (CCC, Brandon)

Funded through the Canola/Flax Canadian Agri-Science Cluster, a joint initiative of AAFC and Canola Council of Canada

Weather-based assessment of sclerotinia stem rot risk

(SC 3.3.2) 
Objective: To quantify the influence of fundamental weather factors on sclerotinia severity and correlate these factors to pathogen incidence in order to develop weather-based assessments of sclerotinia stem rot disease risk. Ultimately, the goal is improved efficiency and efficacy of disease control methods while enhancing the predictability of the disease forecast model.

Defining populations of the L. maculans pathogen in test sites used for canola blackleg resistance trials

(SC 3.3.3)
Objective: To develop a tool for defining populations of the Leptosphaeria maculans pathogen at canola blackleg-resistance trial sites. To develop a set of single blackleg-resistance-gene substitution lines for B.napus canola. To evaluate the effectiveness of these lines for monitoring blackleg populations in the field and for testing L. maculans isolates in the laboratory.

Mitigation of risk to canola from spring flea beetle injury

(SC 3.3.4)
Objective: To quantify the risk of injury by flea beetles to prairie canola production by: a) Determining how environmental factors affect distribution, overwintering survival and spring emergence, flight, feeding levels, oviposition and reproduction of the two principal crucifer-feeding flea beetle species. b) Investigating conditions and reasons for seed treatment failures.
