Small and vulnerable canola plants face many threats during their first three weeks. The crop may need your protection to get through these stages with its top-end yield potential intact. Canola growers are encouraged to walk their fields a couple times a week — or more — until plants are firmly established and growing strong…

Canola is most fragile during the first 21 days after emergence. The small plants are highly susceptible to flea beetles, cutworms, seedling diseases, weed competition and various other threats.
