Key Takeaways:
- AI-equipped sprayers can reduce foliar herbicide use and costs for Midwest corn and soybean producers
- Smart sprayers with artificial intelligence technologies can detect and spray weeds between and in the rows, reducing herbicide input costs without compromising weed control
- Integrated weed management principles, including crop rotations and multiple effective sites of action, are still important when using AI-equipped technology
- Two-boom, two-tank smart sprayers can enable simultaneous broadcast and targeted applications, increasing efficiency and reducing costs
- Traditional one-boom, one-tank systems can still be effective with two passes across the field, using a soil-applied residual product at planting and a targeted postemergence application of foliar herbicides
Introduction to AI-Equipped Sprayers
A new research article published in the Weed Science Society of America journal, Weed Science, has found that AI-equipped sprayers can more efficiently control weeds than conventional broadcast sprayers. The study, conducted by Anita Dille, Ph.D., and her research team at Kansas State University, found that smart sprayers with artificial intelligence capabilities can help reduce foliar herbicide use and costs for Midwest corn and soybean producers. As Dille notes, "This research demonstrated that significant herbicide use reductions are possible with smart sprayers compared with broadcast applications." The study’s findings have significant implications for the agricultural industry, as they suggest that AI-equipped sprayers can be a valuable tool in reducing herbicide use and costs.
The Study’s Methodology
The researchers used a ONE SMART SPRAY sprayer for their study, which was custom-built for small plot research. The sprayer was mounted to a tractor and equipped with a front boom reserved for spot spray nozzles and a rear boom reserved for broadcast applications. Cameras mounted across both booms used advanced imaging technologies to distinguish between row crops and weeds. The AI technologies enabled the smart sprayer to detect and spray the weeds between and in the rows, activating one or more nozzles across the boom depending on the green area detected by each camera. As Dille explains, "The ONE SMART SPRAY sprayer demonstrated the potential to reduce herbicide input costs without compromising weed control."
The Benefits of AI-Equipped Sprayers
The study found that AI-equipped sprayers can reduce herbicide input costs without compromising weed control. As Dille notes, "Herbicide costs in targeted spray applications were less than in broadcast applications." The use of AI technologies enabled the smart sprayer to detect and spray weeds more efficiently, reducing the amount of herbicide needed. This can have significant benefits for farmers, as it can help reduce costs and minimize the environmental impact of herbicide use. Additionally, the study found that two-boom, two-tank smart sprayers can enable simultaneous broadcast and targeted applications, increasing efficiency and reducing costs.
The Importance of Integrated Weed Management
While AI-equipped sprayers can be a valuable tool in reducing herbicide use and costs, the study’s authors emphasize the importance of integrated weed management principles. As Dille notes, "Incorporating integrated weed management principles with this technology, which includes crop rotations, use of residual herbicides, ensuring multiple effective sites of action for the dominant weed species, and two-pass herbicide programs, is still very important." This approach can help to minimize the development of herbicide-resistant weeds and ensure the long-term sustainability of weed management practices.
Conclusion and Future Directions
The study’s findings suggest that AI-equipped sprayers can be a valuable tool in reducing herbicide use and costs for Midwest corn and soybean producers. As Dille notes, "Growers would benefit from the use of two-boom, two-tank smart sprayers for these simultaneous applications as they become available on the market." However, the study’s authors also emphasize the importance of integrated weed management principles and the need for further research into the use of AI-equipped sprayers in weed management. The study’s findings have significant implications for the agricultural industry, and further research is needed to fully explore the potential benefits and limitations of AI-equipped sprayers in weed management.
About the Weed Science Society of America
The Weed Science Society of America is a nonprofit scientific society focused on weeds and their impact on the environment. The society publishes the journal Weed Science, which presents peer-reviewed, original research related to all aspects of weed science, including biology, ecology, physiology, management, and control of weeds. The society’s mission is to promote the understanding and management of weeds, and to provide a forum for scientists and professionals to share their research and expertise. As the study’s authors note, "More information about the study is available online in the article: ‘Evaluating ONE SMART SPRAY for weed control in midwestern U.S. corn and soybean crops.’"
