An agronomy specialist with the Canola Council of Canada says growers should be on lookout for bertha armyworms now that the crop is entering the early stages of podding.
Angela Brackenreed says they have started trapping for moths, although the numbers so far have been low.
She notes it doesn't always make economic sense to spray.
"We really encourage folks to keep in mind economic thresholds before they consider a spray, which factors in the level of crop damage, the expected value of that crop and the cost of the application. It certainly is not a money making application, it`s just a break even point for a spray."
