Dry conditions in Northern growing areas has resulted in uneven emergence. The majority of April planted canola is 2-6 leaf and quite variable within a field. In thin stands of canola consider lowering the action threshold for insect and weed management. Flea beetle pressure continues to remain high in most areas. Scout up to the 4 leaf stage. Control weeds early (1-4 leaf canola stage) to protect yield. Contact herbicides are most effective when applied during the heat of the day.
