A few words from Dr. Eric Prostko, UGA Weed Specialist, on the subject of soybean desiccation.
Recently, I have been getting a few inquiries about soybean desiccation and harvest aids. A few reminders.
1) Official soybean harvest aid rec’s from from the 2024 UGA Pest Control Handbook (pages 263-264);

2) Check out these previous UGA Weed Science Blogs where I addressed this topic:

3) Check out these newer publications from LA and MS. In 2024, these two states collectively planted ~3.42 million acres of soybeans and my colleagues in these states have done a significant amount of research on this topic. Thus, they might know what they are talking about.
