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...

The Alberta Canola director nomination cycle is now open for regions 3, 6, 9, and 12 until October 31, 2024. It is essential for all twelve regions of Alberta Canola to have farmer representation during board discussions. Decisions on government policy and regulation, research funding, and other issues affecting the long-term success of canola farmers...

Band N to reduce losses

With a change in machinery, Red River Valley farmer Brad Erb had to give up his time-of-seeding nitrogen banding. So he opted for the next best thing to reduce losses for his soil type: Fall banding.

Banding N shows clear yield advantage with lower N rates

Key result: In this east-central Manitoba study comparing surface, shallow-band and deep band nitrogen applications, any yield effect from nitrogen losses were minimal when nitrogen was applied at 100 per cent of the recommended rate. Losses were still happening, but the N rate compensated. At 70 per cent of recommended rate, the yield-damaging effect of...

Down Under differences and similarities

Canola production in Australia is a lot like Canada’s in many ways, but Dan Orchard was inspired by some distinct differences.
