Biodegradable carriers for sustained herbicide release in soil

Overview

This solution offers a groundbreaking approach to weed management through the use of biodegradable carriers designed for the controlled, sustained release of herbicides in soil. These carriers are made from Hydrophobic Compressible Organic Materials (HCOM), which are natural and non-toxic, ensuring minimal environmental impact. The primary objective is to extend the duration of weed control while reducing the frequency of herbicide applications, making it both economically and environmentally beneficial.

Technical specifications

The carriers are composed of Hydrophobic Compressible Organic Materials (HCOM), which are currently used in food applications and decompose naturally over time. The innovation allows for the incorporation of various commonly used herbicides, offering flexibility in active material selection. Key features include:

• Controlled release: Ensures a sustained release of herbicides to maintain effective weed suppression.
• Biodegradability: Uses natural, non-toxic materials that decompose in soil, reducing environmental footprint.
• Customizable formulations: Compatible with different herbicides, allowing partners to choose preferred active materials.
• Physical properties: The carrier's shape, density, color, and mechanical properties can be optimized to suit specific needs.

Technology readiness level

This technology is currently at TRL 6, having been validated in relevant environments. Future validation plans include comprehensive testing of the carriers' physical properties, release characteristics, and efficacy in various soil types. The project timeline for these studies is approximately one and a half years, with additional trials to be conducted at agricultural sites to ensure practical applicability.
