Tailored Lignocellulose-Based Biodegradable Matrices with Effective Cargo Delivery for Crop Protection

Area of Science:

• Agricultural Science
• Materials Science
• Environmental Science

Background:

• Controlled release and targeted delivery of agrochemicals are essential for sustainable agriculture.
• Minimizing environmental damage from crop protection chemicals is a key challenge.
• Biodegradable materials offer a promising alternative for agrochemical delivery systems.

Purpose of the Study:

• To develop a cost-effective, biodegradable porous matrix for controlled agrochemical release.
• To investigate the potential of lignocellulose-based materials, specifically from banana plants, for crop protection.
• To explore the influence of mechanical treatment on the matrix properties and release profiles.

Main Methods:

• Fabrication of lignocellulose-based biodegradable porous matrices using banana plant fibers.
• Mechanical treatment of lignocellulosic fibers to tailor matrix properties.
• Systematic investigation of the effect of mechanical treatment on matrix morphology, strength, and porosity.
• Evaluation of the release profiles of model cargos (rhodamine B and abamectin) from the matrices.
• Comparison of release profiles with matrices from non-banana fibrous sources.

Main Results:

• The developed matrices exhibit tunable physicochemical properties for controlled and sustained release of active ingredients.
• Mechanical treatment significantly influences the morphology, strength, and porosity of the matrices.
• The composition and structure of banana fibers result in a unique release profile compared to other sources.
• The "wrap-and-plant" concept enables effective defense against soil-borne pests.

Conclusions:

• Lignocellulose-based biodegradable porous matrices from banana plants are effective for controlled agrochemical delivery.
• The material offers a sustainable and environmentally friendly approach to crop protection.
• The unique properties of banana fibers make these matrices highly suitable for advanced agricultural applications.
