Precision herbicide application for enhanced weed control
This innovative approach leverages precision spraying technology to apply non-selective herbicides between crop rows, enhancing weed control while reducing chemical usage. It targets herbicide-resistant weeds effectively, minimizing crop damage and environmental impact.
Overview
The solution presents a cutting-edge method for improving weed management through precision herbicide application. By employing advanced spraying technology, non-selective herbicides can be applied specifically between crop rows, while selective herbicides are sprayed directly on the crop rows. This dual application strategy significantly enhances weed control by utilizing multiple active ingredients, thereby reducing the total volume of pesticides used. This approach not only helps manage herbicide-resistant weeds more effectively but also lessens reliance on genetically modified crops.
Technical specifications
- Precision spraying technology: Utilizes solenoid-based individual nozzle control for targeted herbicide applications.
- Dual boom system: A dual boom sprayer with 5-inch nozzle spacing allows for precise application of non-selective and selective herbicides.
- Real-time weed identification: Incorporates green on brown identifying technology to ensure precise targeting of weeds.
- Reduced chemical use: By focusing on precision applications, this method minimizes the volume of herbicides required, reducing environmental impact.
Technology readiness level
Currently, the technology is at TRL 3, indicating that the initial research and development have been completed, and the system has been successfully built and is under testing. The ongoing validation involves assessing weed efficacy and crop phytotoxicity throughout the growing season, with the aim of optimizing this approach for commercial use.
