ARA™ Precision Sprayer Cuts Herbicide Application by 84% in Tall Fescue Trial

09/25/26 ARA™ Precision Sprayer Cuts Herbicide Application by 84% in Tall Fescue Trial Oregon State University and Ecorobotix trial demonstrates precision targeting of Poa annua and Italian ryegrass while reducing spray volume to 3.63 gallons per acre, saving 84% across the field. For Willamette Valley grass seed growers, Poa annua (annual bluegrass) and Lolium multiflorum (Italian ryegrass) are particularly problematic weeds. They can contaminate seed, increase cleaning costs, and compete with the crop, making effective control an important part of producing high-quality grass seed.
