Manitoba Insect & Disease Update – Week of June 9 to 13th

A Manitoba Insect and Disease Update for the week of June 9-13, 2014 has been posted at: http://www.gov.mb.ca/agriculture/crops/seasonal-reports/insect-report-archive/2014-06-10-insect-report.html


Current Insect Scouting Priorities

  • Flea beetles: Foliar spraying, in addition to the seed treatments, is occurring in many areas.
  • Cutworm: Dingy and redbacked cutworms seem to be our dominant species.  How long will they feed? Will crops compensate for some cutworm feeding?

Dingy Cutworm

  • Check field edges to assess levels of emerging grasshoppers.

Insect Monitoring Update

Diamondback Moth: It is likely that we had a moderate population of diamondback moth blow into some areas of Manitoba.  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
