ALTERNATIVES TO LAMBDA-CYHALOTHRIN FOR 2023
The Pest Management Regulatory Agency’s (PMRA) re-evaluation decision regarding lambda-
cyhalothrin (e.g., Matador, Silencer, LaBamba, etc.) came into force on April 29, 2023. The new
and updated label for lambda-cyhalothrin indicates that crops treated with lambda-cyhalothrin
cannot be used as livestock feed in Canada. This includes any harvested grain, seed screenings,
byproducts or aftermath. As any crop entering the grain handling system is eligible for use as
livestock feed, this poses a risk of becoming an off-label use.
To aid Manitoba farmers for the 2023 growing season, Manitoba Crop Alliance, Manitoba
Canola Growers Association, Manitoba Oat Growers Association and Manitoba Pulse &
Soybean Growers, in conjunction with Manitoba Agriculture, have collaboratively developed
a factsheet titled ALTERNATIVES TO LAMBDA-CYHALOTHRIN FOR 2023.
The publication provides information on alternative insecticide options for wheat,
barley, oats, canola, flax, soybeans, corn, dry bean, faba bean, peas and sunflower.
