Science Edition 2015—Key practice: Managing cabbage seedpod weevils (when they reach thresholds) with a single insecticide application at early flower stage can reduce pod-stage abundance of lygus bugs and may increase yield by an average of 1.5 bu./ac. Project title, Lead researcher: “Management of lygus bugs and seedpod weevil in canola at the farm level,” 2010-14, Hector...
Read More Science Edition 2014—Key practice: Use seed treatments and early in-crop treatments, if scouting deems them necessary, to protect young plants from flea beetles. Key research: Hallett, Rebecca, University of Guelph. “Assessing the Impact of Swede Midge on Canola Production in the Prairies & Ontario.” Canola Agronomic Research Program (CARP 2005-14). Olfert, Owen and Elliott, Bob, Agriculture and...
Read More Science Edition 2014—Key practice: In Western Canada where the growing season is short, the ideal practice is to apply all fertilizer at the time of seeding. However, if shortages are expected or crops are showing deficiencies, soil-applied applications of nitrogen or sulphur fertilizer after emergence will likely provide an economic benefit. Key research: Guy Lafond, Agriculture and...
Read More Science Edition 2014—Canola growers can experience substantial decreases in yield due to sulphur deficiency. The abstract to the Grant, Malhi and Karamanos review cited above begins with this: “(Canola) has a high concentration of sulphur in its tissue and seed and a particularly high demand for sulphur relative to its yield potential. Therefore, effective sulphur management is...

Science Edition 2014—Most canola crops grown in Western Canada are not short of potassium because most Prairie soils have sufficient potassium levels. Sandy soils with low clay content are most likely to be short of potassium, especially if those fields have been in forages where a large percentage of the biomass is removed each year. Cereals in...
