There are reports of macronutrients and micronutrients being foliar applied to frosted, stalled crops to give the plants a boost. Canola Council of Canada agronomists are not aware of any scientific research to date here in western Canada that supports the economics of this practice. However, if growers do apply a foliar application, they should leave a checkstrip so they can evaluate the final yields. Council agronomists would like to follow fields with this treatment to harvest and use yield measurements to determine if the application was economical. If you are interested in having a Council agronomist help in evaluating your crop, please contact your local regional agronomy specialist listed at the end of this report.
