Seedlings are especially vulnerable to flea beetle damage as the pest can locate and defoliate seedlings shortly after emergence.
If left untreated, the flea beetles can cause poor plant stand, delayed maturity and reduced yield
In Western Canada, these pests can cause yield losses up to 10 per cent, costing growers about $300 million each year, university research says.
Canola farmers have been using BUTEO since 2020.
The Group 4D insecticide delivers rapid uptake and systemic translocation from cotyledon to leaf margins. This enables a quicker-growing canopy and uniform flowering even in conditions where flea beetles thrive.
A BUTEO label expansion to include mustard seemed like a natural progression, Bryson said.
“We identified there was a need for this kind of product in mustard given that these beetles attack it as well as canola” he said. “Expanding the label helps farmers protect those acres and gives them another tool at their disposal.”
BUTEO start insecticide seed treatment will be available for mustard growers for the 2025 growing season.
