Lambda-cyhalothrin label changes now in effect

May 03, 2023

With seeding operations starting to get underway across the prairies.

Farmers are being reminded that the PMRA label changes for lambda-cyhalothrin came into effect on April 29th.

Canola Council of Canada Agronomy Specialist Ian Epp notes in Canada crops treated with the product can no longer be used as livestock feed:

"In Western Canada, we don't really have a segregated market. There will be some contracts maybe, but food and feed do blend together. In a crop like canola specifically - canola can be simultaneously both food and feed. If we are crushing the oil maybe the oil is for food, but the meal that is a byproduct of that processing is often used for feed."

Epp says lambda-cyhalothrin is widely used for insect control in a variety of crops, like flea beetles in Canola.

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.
