Why is Weed Testing Important?

Proper diagnosis of herbicide resistance is key to weed management. Applications of herbicides to resistant populations result in unnecessary herbicide sprayed in the environment and money lost due to herbicide, equipment, and labor expenses.

Also, applying herbicides to resistant weed populations further perpetuates the resistant populations by killing off susceptible plants and allow resistant plants to thrive.

Common Weeds Tested

The major weeds tested in the resistance lab are: Annual bluegrass, goosegrass, and annual sedges/kyllingas. Assays can be adapted to any weed species. Contact the lab for more information.

Collaborators

Battling herbicide resistance requires a team effort. The Herbicide Resistance Diagnostic Lab would like to acknowledge collaborators who help to solve resistance issues and jointly work on solutions for herbicide resistance issues.
