Field-effective R&D methodology for herbicide selectivity using log sprayers and drones
Agrolab A/S presents a novel R&D methodology using log sprayers and drones to enhance herbicide selectivity. This approach enables precise EDx parameter extraction across various conditions, optimizing herbicide formulations and improving crop selectivity and weed control.
Overview
Agrolab A/S has developed an innovative research and development methodology to enhance the selectivity of herbicides in agricultural applications. Utilizing logarithmic sprayers and drone-captured crop imagery, this approach offers a cost-effective and precise method to derive essential EDx parameters, such as ED10 and ED90-ED95, across different dose-response curves (DRCs). These parameters allow for comparisons across various crops and environmental conditions, making it possible to optimize herbicide formulations for improved crop selectivity and weed control.
Technical specifications
- Logarithmic sprayers: Continuously dilute herbicide doses along field plots, generating comprehensive DRCs to extract EDx parameters.
- Drone imagery: Utilizes indices like Excess Green and NDVI to reflect herbicide effects, analyzed with statistically mixed models.
- GPS integration: Increases precision in dose application and data collection.
- Mixed nonlinear models and meta-analysis: Address systematic spraying patterns, enhancing data reliability.
- EDx parameters: Facilitate comparison of herbicide efficiencies across different localities and experimental conditions.
Technology readiness level
This methodology is at Technology Readiness Level 6, indicating that it has been validated in relevant field environments. The system is poised for further optimization and commercial deployment through collaborative efforts and advancements in GPS and drone technologies.
About Agrolab A/S
Agrolab A/S is a prominent agricultural Contract Research Organization (CRO) based in Denmark, founded in 1984. The company specializes in regulatory consulting and field trials for plant protection products, fertilizers, and biocides within the EU North Zone, which includes Scandinavia and the Baltic states. Agrolab designs and executes field trials under Good Experimental Practice (GEP) and Good Laboratory Practice (GLP) standards. Their technical capabilities include hyper-spectral and drone-based imaging, soil scanning, and multispectral analysis to assess crop diseases, seed germination, and plant vigor. As of 2025, the company has restructured into two primary entities, Agrolab Field and Agrolab Consulting, to provide specialized support across the entire product registration lifecycle.
These services are critical for agricultural and chemical companies seeking to register and bring sustainable plant protection products to market. By ensuring compliance with rigorous regulatory documentation requirements, Agrolab enables clients to navigate complex market entries in the EU. The company supports a wide range of organizations, from large established firms to early-stage startups, through services ranging from initial proof-of-concept trials to final dossier submission. Their work contributes to safer food production and environmentally responsible agricultural practices by facilitating the development of effective, approved solutions.
