The product protects wheat, oats, barley, rye, and triticale

A new crop protection from Bayer is available to Canadian cereal farmers.

Raxil Rise builds on the existing Raxil formulation of Group 3 Tebuconazole, Group 3 Prothioconazole, and Group 4 Metalaxyl, by adding Group 7 Penflufen into the mix.

“This helps enhance broad spectrum protection, and specifically with Fusarium and with true loose smut (TLS) in barley for that early season protection,” Bryan Bryson, Bayer’s crop science marketing portfolio lead for crop protection in Western Canada, told Farms.com.

The fungus Ustilago nuda infects the embryo of the barley seed and causes TLS.

“Losses from infection can range from 1% to 40% and in general, the percent yield loss is equal to the percent of the heads infected with TLS,” Jeremy Boychyn, director of research, agronomy & extension with Alberta Grains, said in March 2022.

Raxil Rise also protects cereal crops against diseases like leaf stripe, seed rot, and seedling blight.

Bayer trial data indicates the product works as intended.

“Starting from the treating experience we had a lot of positive feedback,” Bryson said.

The company used Raxil Rise in more than 100 trials across the Prairies, including farmers, seed treaters, and agronomists.

Those involved studied everything from Raxil Rise’s pink colorant to its micro dispersion technology.

“The product stayed on the seed and not on the equipment, so you can be sure the product is following the seed right into the furrow and is available to the seed,” Bryson said.  

Farmers have flexibility in the volume of Raxil Rise they wish to order.

The product comes in 10 L jugs, 125 L drums, or 1,000 L totes.

Growers will also have flexibility in terms of tank mixing options.

“Farmer looking to add insecticide protection can add Stress Sheld without any issues,” Bryson said.

Growers interested in learning more about Raxil Rise can contact a local Bayer rep.

Understanding the Basics of the Renewable Fuel Standard

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.
