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.

Real-time diagnosis in the field

Key Result: Researchers were able to develop and validate nine real-time qPCR assays targeting eight different phytoplasma (aster yellows) species along with P. brassicae (clubroot) and L. maculans (blackleg). This project provides tools for producers and regulators to obtain timely information on plant disease prevalence and spread, which will aid efforts to contain and control...

Aim for consistent seed depth

Planters are the ultimate tool for precise and consistent seed placement,
which benefits canola stand establishment. But are they worth it?

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...

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...
