A Manitoba Insect and Disease Update for the week of June 16-20, 2014 has been posted at: http://www.gov.mb.ca/agriculture/crops/seasonal-reports/insect-report-archive/2014-06-17-insect-update.html
- Cutworms continue to be an issue in some areas.
- Flea beetle populations remain a concern in some areas, although the cool weather and advance of many canola fields to stages more tolerant to feeding has resulted in decreased damage.
- Grasshoppers are emerging, but generally still in the first and second instar stages.
- Alfalfa weevil larvae are starting to be noticed in some alfalfa fields.
- Brown spot (Septoria) and bacterial leaf blight have been observed in soybeans.
- Rust has been found in some fields of sunflowers.
- Insect Monitoring Program: Some moderate levels of diamondback moth have been recorded in traps in the Eastern, Central and Northwest regions. Weekly maps for the monitoring program for diamondback moth can be found at: http://www.gov.mb.ca/agriculture/crops/insects/diamondback-moth-monitoring.html
