Syngenta and DuPont say they expect a new herbicide chemistry class to be created by 2023, after announcing the publishing of a joint patent on Monday.

Collaboration between the two companies on the project started in 2015 and has resulted in a patent for “Substituted cyclic amides and their use as herbicides.”

“We are very pleased that our collaboration with Syngenta has extended into a joint research project for a new herbicide chemistry class,” said Timothy P. Glenn, president, DuPont Crop Protection.

Details on where they see this new herbicide being used are thin, but it has entered into the “pre-development” stage and is expected to be launched in 2023, the companies say.

“We are excited to be working again with DuPont on this herbicide research and development project. Success in this field will bring much needed new technology to farmers in the increasingly challenging area of weed management, including resistance,” said Jon Parr, president for Crop Protection at Syngenta.
