Lorox L herbicide label reinstated for celery

Mar 12, 2025

The Pest Management Regulatory Agency (PMRA) recently approved a minor use label expansion registration for Lorox L herbicide for control or suppression of labelled weeds in celery in Canada. Lorox L herbicide was already labeled for management of weeds on a wide range of crops in Canada. This minor use proposal was submitted by the registrant, Tessenderlo Kerley Inc. (TKI), to reinstate the use following a phase-out originally announced in RVD2020-10 after new supporting information was submitted to PMRA for review.

The following is provided as an abbreviated, general outline only. Users should be making weed management decisions within a robust integrated weed management program and should consult the complete label before using Lorox L herbicide.

Video: Understanding the Basics of the Renewable Fuel Standard

On Friday, April 24, 2026, from 12 noon–1:00 ET, the Penn State Center for Agricultural and Shale Law, alongside the Pennsylvania Department of Agriculture’s (PDA) Agricultural Business Development Center (ABDC), presented this webinar in the Understanding Agricultural Law Educational Series, a course designed to develop subject matter literacy and competence on fundamental issues of agricultural law for attorneys and business advisors who work with or represent agricultural or rural clients but may not necessarily specialize in agricultural law:

“Understanding the Basics of the Renewable Fuel Standard”

The Clean Air Act’s Renewable Fuel Standard (RFS) program requires transportation fuel sold in the United States to contain a minimum volume of renewable fuels such as ethanol, biodiesel, or advanced biofuels. Established by the Energy Policy Act of 2005 and later expanded by the Energy Independence and Security Act of 2007, the RFS is implemented by the U.S. Environmental Protection Agency (EPA) in collaboration with the Department of Energy and the U.S. Department of Agriculture (USDA).

This webinar provides an overview of the legal authority and structure for the RFS program and explain how it works, including the program’s system of Renewable Identification Numbers (RINs) and categories of renewable fuels. Additionally, this webinar addresses EPA annual volume requirement rulemaking and associated recent legal issues.
