Quick Hitters

Heat revives flea beetles. After a few weeks with no flea beetle pressure, they have shown up again with the heat. Crop seeded recently will still have seed treatment protection, but for crop seeded weeks ago that have been slow to establish, scout closely.

Cutworms are still feeding and damage is the most widespread we’ve ever seen. “There is serious spraying going on,” says Doug Moisey. One farmer around Rycroft, Alta., sprayed 1,500 acres for cutworms in the past week. Remember: Look for blank areas in the field as well as cut canola plants. Both can be signs of cutworm damage. For more on cutworms as well as weeds and other insects, listen to Doug Moisey on ACPC radio.

Look for apothecia as an early sign of sclerotinia threat. Sclerotinia stem rot prevention requires a fungicide application on the petals at 20% to 50% flower, and the tiny mushroom-like apothecia (pictured below) are a sign of sclerotinia to come. Use the CCC’s Canola Disease Scouting & Risk Assessment Card to help determine whether a spray is warranted.


Give yellow canola time to recover. Rather than spend any money to save yellow canola, leave it be until the ground dries up and the crop starts growing again. When that happens, look for white healthy roots as a sign the crop can recover. Brown decaying roots mean a dead crop that isn’t worth further investment.

Tank mix tip: Before tank mixing herbicides and insecticides, make sure the timing is right for all target pests. Note that for cutworm in particular, the best time to spray is later in the evening when they’ve moved up to the surface. Liberty, which works better in the heat of day and full sunlight, will provide optimal performance with a separate application. With glyphosate, the evening application will generally not interfere will weed control. Also cutworms are not usually general across the whole field, so spot spraying is often the best practice.

Meet these crop insurance deadlines

AFSC’s deadline to report acres that remain unseeded due to excessive spring moisture is today, June 23. Late claims are not accepted.

For Saskatchewan growers, the SCIC deadline to file seeded acres reports and submit unseeded acreage claims without penalty is June 25. SCIC reminds growers that they can get an establishment benefit on acres that were seeded and not established due to flooding. In this situation, if the crop could not be reseeded by June 20 growers may be eligible for an unseeded acreage benefit.

For Manitoba growers, the MASC deadline to file their excess moisture insurance claims was June 22, but growers can still file up to June 30 with a late filing fee. The deadline for filing seeded acreage reports is June 30.

We remind growers to call their insurance provider to get an assessment before turning under any crop or reseeding it to greenfeed.
