The Pest Management Regulatory Agency (PMRA) recently announced the approval of an URMULE registration for Movento® 240SC Insecticide for control of swede midge on Brassica vegetables, crop group 5 inCanada.  The active ingredient spirotetramat was already labeled on a wide range of vegetables, fruits and field crops.

The minor use project for swede midge on Brassica vegetables was sponsored by the Minor Use office of OMAFRA in 2010 as a result of minor use priorities established by growers and extension personnel.  Swede midge has been a devastating new pest of Brassica crops in Canada in recent years.  This minor use label expansion for Movento® 240SC Insecticide is a significant step towards developing an improved pest management toolkit for this pest in Canada.

The following is provided as a general outline only.  Users should consult the complete label before using Movento® 240SC Insecticide.

For swede midge on Brassica vegetables (including broccoli, broccoli raab (rapini), Brussels sprouts, cabbage, cauliflower, cavalo broccolo, Chinese broccoli (gai lon), Chinese mustard cabbage (gai choy), collards, kale, kohlrabi, mizuna, mustard greens, rape greens) Movento® 240SC Insecticide can be used for control of swede midge at a rate of 220 – 365 mL per ha applied in a minimum of 500 L water per ha.  The label also recommends the addition of a spray adjuvant such as a non-ionic adjuvant, methylated seed oil or horticultural oil.  Begin applications when swede midge are first noticed.  Reapply when monitoring indicates it is necessary but do not apply more than once every 7 days.

Do not apply more than 730 mL per ha per year and do not apply within 1 day of harvest for Brassica vegetables.

Movento® 240SC Insecticide should be used in an integrated pest management program and in rotation with other management strategies to adequately manage resistance.

Follow all other precautions and directions for use on the Movento® 240SC Insecticide label carefully.

We wish to thank Dr.Rebecca Hallett (Univ. of Guelph), Pierre Lafontaine (CIEL-CVP, Quebec), Dr. T. Shelton (Cornell Univ., NY) and Bayer CropScience personnel for assisting with the research to support this label expansion.  We also wish to thank the personnel of Bayer CropScience Inc. for their support of this registration and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
