Spring Frost: Take a Few Days to Assess Damage

Jun 04, 2013

Canola Council of Canada Canola Watch Alert

Frost hit some canola growing regions on the weekend (eastern Saskatchewan and Manitoba). Two key questions arise after a frost:

1. Did the crop survive? (Do I need to reseed?)
2. When can I resume weed control?

How to answer the questions:

Did the crop survive? It can take a few days before you can accurately answer that question. With a light frost of 0 C to -2 C, the risk of crop damage is minimal. With a heavy frost that kills off the cotyledons, it takes a few days before new leaves will start emerging from the growing point between the cotyledons. (Top photo) If no growth occurs within this time, the plant is likely dead. Also, if the stem (hypocotyl) is pinched off or the plant flops over, the plant will likely die. The pinched off or broken stem cannot provide nutrients to the growing point. (Bottom photo) See a video.

Check the whole crop 24-28 hours after a frost and again 3-4 days after a frost to assess the situation. Click here for tips on how to check the field.

Video: Finding a Balance of Innovation and Regulation - Dr. Peter Facchini

Regulations help markets and industry exist on level playing fields, keeping consumers safe and innovation from going too far. However, incredibly strict regulations can stunt innovation and cause entire industries to wither away. Dr. Peter James Facchini brings his perspective on how existing regulations have slowed the advancement of medical developments within Canada. Given the international concern of opium poppy’s illicit potential, Health Canada must abide by this global policy. But with modern technology pushing the development of many pharmaceuticals to being grown via fermentation, is it time to reconsider the rules?

Dr. Peter James Facchini leads research into the metabolic biochemistry in opium poppy at the University of Calgary. For more than 30 years, his work has contributed to the increased availability of benzylisoquinoline alkaloid biosynthetic genes to assist in the creation of morphine for pharmaceutical use. Dr. Facchini completed his B.Sc. and Ph.D. in Biological Sciences at the University of Toronto before completing Postdoctoral Fellowships in Biochemistry at the University of Kentucky in 1992 & Université de Montréal in 1995.
