University trials find ONE SMART SPRAY cuts herbicide costs in corn and soybean when paired with residual herbicides
ONE SMART SPRAYONE SMART SPRAY system
Researchers led by Kansas State University tested the system in Kansas and Illinois in 2022–2023. Programs combining a broadcast soil-residual herbicide with spot-sprayed foliar herbicide gave weed control similar to full broadcast, while spot-spraying alone was consistently the weediest.
- Average savings in Kansas 2023: about US$123/ha in soybean and US$43/ha in corn
- Illinois corn: broadcast ~US$188/ha vs ~US$128–158/ha with the system's settings
- Authors recommend the most sensitive 'Efficacy' setting for in-crop spraying
- Costs exclude sprayer running and subscription fees
