Flea beetles still of concern in Manitoba

June 16, 2015 - Manitoba Agriculture, Food and Rural Development (MAFRD) has posted the Manitoba Insect and Disease Update for this week online. Highlights include:

  • Insect feeding has been minimal in cereals, however watch for signs of feeding or larvae of cereal leaf beetle so we can assess levels of parasitism if these are present.
  • In canola, flea beetles are still present at potentially damaging numbers for fields that may not have 3 or 4 true leaves yet.
  • In forage crops, alfalfa weevil is at high levels in some alfalfa fields in the Interlake and Dauphin area.
  • Cutworms continue to be of concern in some fields. In cooler springs cutworms can continue to be a concern into late June. Consider the size of larvae when making control decisions. If there are a lot of larvae under 2.5 cm, then there is still the potential for considerably more feeding damage. If the majority of larvae are over 2.5 cm, feeding will be ending soon.
