A Manitoba Insect and Disease Update for the week of August 4-8, 2014 has been posted at: http://www.gov.mb.ca/agriculture/crops/seasonal-reports/insect-report-archive/insect-update-2014-08-08.html.
- Scouting for canola diseases has begun. Blackleg, root rots, white mold, aster yellows and alternaria pod blight will be surveyed.
- Lygus Bugs in canola – The growth stage where canola has the most potential to have yield reduced by Lygus bugs is the early-podding stage.
- In corn, scouting for Goss’s wilt and leaf blight disease will help growers understand the status in their crop. A few plants are showing common smut, which is not a serious disease.
- Some have been asking about red mites seen on the wings of grasshoppers.
