New wireworm control active ingredient PMRA-approved

October 21, 2020  By Top Crop Manager

Starting in 2021, corn, potato and cereals growers will have a wireworm control option that can kill the pest.

On Monday, BASF Canada Agricultural Solutions received registration for Broflanilide from Health Canada’s Pest Management Regulatory Agency (PMRA). Broflanilide, the first IRAC Group 30 available in Canada, is a powerful insecticide in two new unique products: Teraxxa F4 insecticide and fungicide for cereals and Cimegra for potatoes and corn. Both products will be available to Canadian growers for the 2021 season.

Broflanilide features a new mode of action and targets all wireworm larval stages, which helps suppress and control potential seasonal recovery of wireworm populations. While prior solutions intoxicated wireworms, leaving a potential for their recovery, Broflanilide binds to the wireworm’s central nervous system, causing hyperactivity of nerves and muscles, which ultimately eliminates the pest altogether.


Teraxxa F4

Teraxxa F4 insecticide and fungicide seed treatment is a new tool for cereal growers who have dealt with crop damage and loss due to wireworms. The solution includes four fungicide active ingredients in a convenient pre-mix for broad spectrum protection against seed and soil-borne diseases and ease of application both on and off the farm.


Cimegra insecticide provides control of prevalent and difficult-to-control chewing insects in potatoes and corn, including wireworm, for in-season management and reduction of resident populations.

“Cimegra insecticide can be easily incorporated into an integrated pest management strategy. It offers a unique mode of action that delivers lasting efficacy with no known resistance, making it an excellent new tool for the management of wireworms” said Allison Friesen, technical market specialist, insecticides and seed treatment, with BASF.
