Precision sprayers can detect and treat weeds simultaneously in real-time, enabling targeted weed management. This approach has the potential to reduce herbicide usage and associated costs. Although large-scale commercial precision sprayers are available for row crops, their weed control efficacy has not been extensively compared with traditional broadcast sprayers under field conditions.

New research evaluated the performance of precision sprayers (Greeneye Technology and John Deere) in corn and soybean production fields. Results indicated that both precision sprayers provided grass and broadleaf weed control comparable to broadcast sprayers with herbicide savings dependent on weed infestation.
