Got pods? It’s time to scout for bertha armyworm

July 19, 2018

We’re nearly through the annual flight for bertha armyworm, and numbers are certainly concerning in some areas. If you’ve got canola headed in to podding, you need to scout — this nasty pest can cause a lot of damage in a short time.

As canola moves past flowering and into podding, bertha armyworm will move from consuming the leaves, to consuming pods and this is when they cause their real economic damage. With a variable crop in many parts of the Prairies, the typical late-July/early-August scouting window may need to be expanded somewhat.

In this episode of the Canola School, Shaun Haney caught up with Alberta Agriculture pest management specialist Scott Meers to talk about the importance of surveys and scouting, when to start assessing the need to control bertha, and what products to use if the pest reaches threshold in the coming weeks.
