Scout For, Control Cressleaf Groundsel This Fall

By Mark Loux

Cressleaf groundsel, which is poisonous to livestock, has caught some hay and livestock producers by surprise when they discover it in late spring in hay or pasture.  Some hay producers have had to discard hay from first cuttings due to an abundance of this yellow-flowered weed.  Cressleaf groundsel is a winter annual weed that is easily controlled in the fall, when in the rosette stage, in most crop situations.  Take time to scout fields this fall to determine whether cressleaf groundsel is present, especially in new summer seedings or fields with a history of this weed problem.

Video: Robotics and Automation for Weed Management

Dr. Jed Colquhoun explores the rapidly evolving field of robotics and automation in agricultural weed management. He contextualizes the need for alternative weed control methods due to rising herbicide resistance, regulatory restrictions, and labor shortages. The presentation showcases cutting-edge technologies such as laser weeders, spot cultivators, and AI-driven imaging systems, with a focus on real-world research using the Carbon Robotics laser weeder in onion production. Viewers will learn about the effectiveness, precision, and potential yield benefits of these tools, as well as their fit in high-value crops and labor-limited systems. The video concludes with a look at future directions in automation and commercialization for farms of all sizes.
