Research on pennycress aims to go from weed to cash crop

Sep 07, 2023

Researchers are helping Midwest farmers explore what crops they might add to a traditional corn-soybean rotation. Pennycress is being studied for its potential to grow as a cash crop between soybeans and corn.

Illinois State University crop scientist and researcher Nicholas Heller showed farmers on tour at ISU’s University Farm in Lexington Aug. 15 some things learned, so far, about growing pennycress here.

This research is just part of the 440-acre crop and livestock farm in Lexington that welcomes about 3,000 visitors a year and helps educate 420 ISU ag students annually, said ISU agricultural professor Rob Rhykerd on the field day sponsored by the Illinois Soybean Association.

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.
