Canola: Planting is 95 % complete in southern growing areas and nicely started in northern districts. April planted fields are at cotyledon-1st leaf stage. Flea beetles are now actively feeding. Populations are highest in field borders. Threshold for control is 25% leaf feeding. Weeds are emerging with the canola. Critical weed control period is 1 – 4 leaf stage. Schedule weed control for early stages to protect yield and avoid weather or other delays.
