The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registrations for Entrust and Success insecticides for control of cabbage maggot on Brassica leafy greens crop subgroup 4-13B and Brassica head and stem vegetables, crop group 5-13 in Canada. Entrust and Success insecticides were already labeled for use on a wide variety of crops in Canada for control of several insects.

 

These minor use projects were submitted by Quebec as a result of minor use priorities established by growers and extension personnel.

 

The following is provided as an abbreviated, general outline only. Users should be making pest management decisions within a robust integrated pest management program and should consult the complete label before using Entrust or Success insecticides.
