Thresholds are 100-150 larvae per square metre in immature to flowering plants and 200-300 larvae per square metre (20-30 per square foot) in plants with flowers and pods. While these nominal thresholds are based on dense stands of 150-200 plants per square metre, plant population is not a major factor. Fewer plants will have more branching and more pods, so…

Yield-robbing levels of disease will be easy to spot in canola fields now and through to harvest. This is a great time to start your pre-harvest disease scouting. The CCC has released a new pre-swath disease scouting video available on www.canolacouncil.org on proper identification including tips and close up views of typical damage from the major diseases…

When strange patterns of damage in canola fields line up perfectly with the sprayer boom width or follow typical drift patterns, phone calls and finger pointing begin. Explanations can be simple: The wrong product was added to the tank, or the right product was applied but on the wrong field. But situations are often much more complicated — and made…
