Oligonucleotide-based Method Offers Precise Control Over Weeds

March 16, 2022

A Colorado State University-led project is developing a weed control method that is based on the application and methods of the latest gene-silencing weed control technology. The objective is to help farmers eliminate weeds using genetically precise and sustainable methods.

The method uses antisense oligonucleotides to penetrate cells of weed plants and target single strands of RNA that will be delivered through a nanoparticle-based, shelf-stable spray. The method is very specific to the target weeds and will leave crops unharmed. The project will initially target the Palmer amaranth as its test case, a hardy and aggressive pigweed that exhibits extensive herbicide resistance.

If successful, the method will provide farmers with a weed control system that can be easily applied yet is safe for both humans and the environment.
