Dr. Rodrigo Werle Assistant Professor & Weed Specialist Department of Agronomy
In this demonstration video, Dr. Rodrigo Werle discusses some of the considerations when using contact-based products such as PPO-inhibitors (group 14) and glufosinate (group 10) for POST-emergence weed control in soybeans. To be effective, these products should be sprayed to small weeds, preferably under low population density, and with high gallonage (GPA) with recommended adjuvants. Small weed size and good spray coverage are crucial for efficacy of contact herbicides.
