Weed Solution Mixes Drones And Traditional Sprayers
As herbicide costs rise and regulations increase, grain farmers look for new, cost-effective ways to address these issues.
Aerial WeedScout from Sentera combines advanced Direct Georeferencing technology with drone flights, driving AI-powered insights and delivering targeted spray prescriptions. After surveying fields at high speed, drones measure weed size, location and type using advanced imaging technology to distinguish weeds from crops. They detect even small weed patches as tiny as a quarter inch. This enables precise identification and mapping, which is critical for effective weed management.
The drones can fly over 100 acres per hour. After analyzing the collected data, a tailored prescription is delivered to the grower, ready for immediate application. This rapid turnaround ensures timely and effective weed control.
“A key advantage of the Aerial WeedScout approach is the time between the weed detection and the sprayer application,” says Sentera CEO Brian Wenngatz. “This time window, often just a few hours, allows the agronomic advisor or farmer to review the insights, improving decision-making.”
Wenngatz explains that the process can prioritize fields and plan sprayer and truck logistics while optimizing tank mixes and volumes.
“It’s a system advantage that we more simply call ‘know before,’” he says.
Wenngatz says the best time of year to complete the process depends on the crop and weed growth patterns, but early detection during the post-emergence stages allows for the most cost-effective treatment.
The system is designed to integrate with existing precision sprayers equipped with nozzle or section control, ensuring easy adoption without significant upfront investment.
“With a targeted prescription in hand, sprayers can maintain commercial speeds, achieving broadcast-equivalent weed control with fewer inputs, reduced tank refills, and less idle time waiting for tender trucks,” Wenngatz says. “This scalability allows for rapid assessment and prescription delivery, making it even more suitable for operations of larger size and scale.”
Aerial WeedScout doesn’t recommend specific products or rates, believing that these decisions are best left to the farmer and their trusted advisors.
Currently, operations are focused on soybean crops in the Midwest U.S., with corn and cotton solutions available in 2026.
Sentera is preparing a limited release for the 2025 season, partnering with strategic industry and channel partners.
“It’s essential this technology be delivered to growers via their trusted advisors who can best utilize the ‘know before’ insights to prescribe the right product mix, rate and timing for maximum efficacy on weed control,” Wenngatz says.
Interested parties are encouraged to visit the website to learn more and express interest in being a participant in their 2025 Aerial WeedScout offering. Pricing will be communicated as distribution agreements are finalized.
