Provincial entomologists provide insect pest updates throughout the growing season so we have attempted to link to their most recent information:
- Manitoba's Insect and Disease Update which includes lygus in canola, wheat midge, and a few sites showing moderate risk levels for bertha armyworm based on phermone trap interceptions (July 27, 2016, prepared by John Gavloski and Pratisara Bajracharya).
- Saskatchewan's Crop Production News includes pre-harvest intervals (PHI) for a long list of field crop pesticides in Issue 6, prepared by Danielle Stephens. As the report notes, "all pesticides have a PHI" specific for product and crop type. The PHI prevents crops exceeding Maximum Residue Levels (MRL) that will affect the quality of seed in terms of export.
- Watch for Alberta Agriculture and Forestry's Call of the Land for updates from Scott Meers who recently provided an update (posted on July 28, 2016) noting completion of Bertha armyworm pheromone trap monitoring and lower numbers throughout Alberta, low numbers of the orange-morph of English grain aphids, and swede midge in the northeast of Alberta.
