Ideal seeding speed depends on drill, conditions

An even seeding depth across all rows will improve canola uniformity and seed survival, but the seeding speed to achieve this consistency will depend on the drill, soil type and field conditions. It helps to run your own tests.

Bertha armyworm monitoring system still works

Key result: The current system for monitoring potential bertha armyworm outbreaks is based on a pheromone trap network developed in the 1970s (Steck et al. 1979) and improved in the 1980s (Struble et al. 1984). This study tested the efficiency of this system in the context of current canola production and determined the monitoring and...

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...
