This study introduces a novel pesticide delivery system using 2D MXene (Ti3C2) nanomaterials for enhanced plant protection. The new formulation improves pesticide solubility, stability, and controlled release, offering effective pest control with biosafety.
Area of Science:
- Materials Science
- Agricultural Science
- Nanotechnology
Background:
- Pesticide delivery systems are crucial for efficient agricultural practices.
- Hydrophobic and unstable pesticides like Avermectin (AV) present formulation challenges.
- Nanomaterials offer potential for improved pesticide delivery and efficacy.
Purpose of the Study:
- To develop a multifunctional nanomaterial-based pesticide delivery system using 2D MXene (Ti3C2).
- To enhance the properties of Avermectin (AV) for improved pesticide application.
- To evaluate the efficacy and biosafety of the novel formulation for plant protection.
Main Methods:
- Synthesis of AV@Ti3C2 nanoformulation via adsorption of Avermectin onto Ti3C2 nanomaterial.
- Characterization of loading capacity, water solubility, pH-responsive release, and photostability.
- Bioactivity assays to assess antipest activity and biosafety tests on maize germination and growth.
Main Results:
- Achieved a maximum Avermectin loading capacity of 81.44% onto Ti3C2.
- Demonstrated significantly improved water solubility and pH-responsive slow-release behavior compared to conventional AV.
- Exhibited excellent photostability under UV irradiation, prolonging pesticide persistence.
- Showcased sustained and enhanced antipest activity with satisfactory biosafety for maize.
Conclusions:
- AV@Ti3C2 nanoformulation represents a promising candidate for effective and sustainable pest control.
