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 say they are not aware of any scientific research in Western Canada of this practice. However, if growers do try it, 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. – Canola Council of Canada
