Lambda-cyhalothrin insecticide cancelled for apples and peaches

Feb 07, 2025

The Pest Management Regulatory Agency (PMRA) has updated its guidance on the pyrethroid insecticide, lambda-cyhalothrin. While the agency has reinstated certain feed uses, it has cancelled use on apples and peaches at the request of registrants Syngenta and Sharda-CropChem Limited.

Here’s a shortened version of the background provided by PMRA.

Lambda-cyhalothrin is a synthetic pyrethroid insecticide used to control many types of insect pests in various settings. It is used on greenhouse food crops, terrestrial food and feed crops, shelterbelts, turf lawns, livestock, buildings, and ornamental plants. It has been registered for use in Canada since 1996.

On 29 April 2021, Health Canada's Pest Management Regulatory Agency (PMRA) published the Re-evaluation Decision RVD2021-04, Lambda-cyhalothrin and its associated end-use products. As a result of the re-evaluation decision, several uses were cancelled due to human health concerns.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
