Evaluating Frost Damaged Canola

Canola seedlings can with stand a considerable frost (-5 to -8 0 C) if plants have become acclimatized following a few days of cold temperatures.  However, canola seedlings growing under warm conditions will be tender, and can be killed by even a f few degrees frost. Ice crystals will form on the leaf surface before they form within cells causing damage.

Prior to taking any action, wait four to five days to assess any damage.

Check the growing point for green colour at the centre of the leaf rosettes.  Although the cotyledons or other leaves may be black, re-growth can occur in 4-10 days depending on weather conditions.

Video: Syngenta Ag Stories - Reanna Hagel, Channel Marketing Manager

Growing up on a cow-calf operation and small feedlot near Lumby, BC, Reanna learned agriculture the hands-on way with her sister on the family farm. Today, as Channel Marketing Manager for Syngenta Canada, what Reanna loves most about her work is simple: the customer is always at the centre. Whether that's a grower or a channel partner, she understands them on a personal level - because she's the daughter of one. But for Reanna, supporting ag doesn't stop at her job. She volunteers with local 4-H clubs, lends a hand to her farming neighbours, and is raising her own kids to understand and respect the land. Her advice to the next generation? "It's an amazing time to be in the industry - it's going to look completely different in 20 years. To be part of the evolution is very exciting."
