Wheat Head Armyworm a Sporadic, But Insidious Pest

Nov 28, 2022

The wheat head armyworm are a random threat and hard to find in Alberta fields.

An army could be invading your field at this very moment, and you might not even know it.

The wheat head armyworm is a sporadic pest that feeds on cereal grains such as wheat and barley here in Alberta and the rest of the Prairies. While its usually a minor nuisance, it can occasionally cause significant damage to the kernels of a cereal crop which can result in the crop being downgraded when it’s screened at an elevator. In fact, one wheat head armyworm can wipe out the equivalent of an entire head of wheat in a single day.

Part of the challenge for farmers when it comes to dealing with wheat head armyworms is that they can be extremely difficult to spot in a field, says Tyler Wist, a research scientist in field crop entomology for Agriculture and Agri-Food Canada (AAFC).

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.
