A number of pest and beneficial insects can have a significant impact on canola production. Since this impact can vary between locations, conditions and years, effective scouting strategies at the correct time, proper damage assessments and accurate An economic threshold is the level of infestation (ex. pest insect density) at which lost yield (ex. due to feeding/insect pest damage) exceeds the cost of the chemical and its application. More utilization will help grower manage insects throughout the growing season for a successful canola crop.
