Frost Damage to Rye

Jun 11, 2021

Evidence of the freezing temperature causing damage to winter rye has just started to become visible in recent days (Photo 1). Affected florets have bleached appearance. When you pull back the glumes you will see that the anthers halted development and have not been extruded/pushed out. Neither are any kernel developing in these pale white florets.

Photo 1 - Frost damage on individual spikes of rye. Notice the pale, bleached glumes of the affected florets and the absence of extruded anthers.

I suggest that you contact your crop insurance agent if you have multi-peril crop insurance on your winter rye as this frost damage may fall under the adverse weather conditions cause of losses.

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.
