J. Chaput, OMAFRA, Minor Use Coordinator,Guelph

The Pest Management Regulatory Agency (PMRA) recently announced the approval of URMULE registrations for SUCCESS 480 SC and ENTRUST 80 W Naturalyte Insect Control Products for control and suppression of several new pests in Canada on bulb vegetables (crop subgroup 3-07B – please see table below for list of bulb vegetables covered by this registration. Note that this reigstration does not cover crop subgroup 3-07A) and Brassica vegetables (crop subgroup 5). Success (spinosad) and Entrust (organic formulation of spinosad) were already labeled on a wide range of fruit, vegetable, ornamental and turf crops for a variety of insect pests. 

 These minor use registrations target several key pests of important specialty crops in Canada and will help to provide a more robust pest and resistance management strategy.  Furthermore, organic producers of the approved crops now have wider access to the Entrust formulation which provides them with a very useful management tool.

 The following table is provided as a brief, general outline only. Users should consult the complete Success and Entrust labels for timing, water volumes and other guidance before using these products. 



Success (rate product)

Entrust (rate product)


Subgroup 3-07B (green onion, leeks, chives [fresh leaves], shallots [fresh leaves], leeks, bunching onion, tree onion [tops], welsh onion [tops]) Leek moth (suppression) 218 mL per ha 132 g per ha Maximum 3 applications per year  at 7 to 10 day intervals; PHI 3 days

Follow all other precautions and directions for use on the Success and Entrust labels carefully.

 Success and Entrust should be used in an integrated pest management program and in rotation with other management strategies to adequately manage resistance.

 These minor use projects were sponsored over the course of several years by Agriculture andAgri-FoodCanada, PestManagement Centre (AAFC-PMC) as a result of priorities established by growers and extension personnel.  We wish to thank researchers and extension personnel in several provinces who contributed efficacy data to support several of these projects.  We also wish to thank the personnel of Dow AgroSciences Canada 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.
