Matador®/Warrior® Insecticide labels expanded via Minor Use Program for control of thrips on Brassica crop subgroup 5A

J. Chaput, OMAFRA, Minor Use Coordinator, Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of URMULE registrations for MATADOR®/WARRIOR® INSECTICIDE for control of thrips on head and stem Brassica vegetables, crop subgroup 5A in Canada. The active ingredient cyhalothrin-lambda was already labeled on a wide range of crops including grains, oilseeds, vegetables and fruits. Note that Warrior® will eventually replace Matador® in the marketplace.

The minor use project for Brassica vegetables was sponsored by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) in 2003 as a result of minor use priorities established by growers and extension personnel. The minor use label expansion for Matador®/Warrior® Insecticide is a significant step towards developing an improved pest management toolkit for this pest in Canada.

The following is provided as an abbreviated, general outline only. Users should consult the complete label before using Matador®/Warrior® Insecticide.

Crop(s) Pest Rate (mL/ha) No. apps/ year Pre-Harvest Interval
Brassica head and stem vegetables, subgroup 5A Thrips 188 3 1 day (mechanical harvest of cabbage)

3 days (mechanical harvest of all other crops in subgroup 5A)

6 days (hand harvest)

Matador®/Warrior® 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 Matador®/Warrior® Insecticide labels carefully.

We also wish to acknowledge the personnel of Syngenta Crop Protection Canada for their support of these registrations and the personnel of the Pest Management Regulatory Agency for evaluating and approving this important pest management tool.
