Chitosan/silica: A hybrid formulation to mitigate phytopathogens

Area of Science:

• Agricultural Science
• Environmental Science
• Materials Science

Background:

• Indiscriminate synthetic pesticide use causes environmental and health issues.
• Developing sustainable alternatives for plant disease management is crucial.
• Biological agents and resistance elicitors are key alternatives.

Purpose of the Study:

• To review silica and chitosan properties and functions in plants.
• To assess their role in combating soil and aerial phytopathogens.
• To explore novel hybrid formulations for future disease management.

Main Methods:

• Literature review of silica-based materials and chitosan.
• Analysis of their dual mode of action (direct and indirect mechanisms).
• Evaluation of nano-silica and chitosan as carriers for active agents.

Main Results:

• Silica and chitosan exhibit promising dual-action mechanisms against plant pathogens.
• Nano-silica and chitosan serve as efficient carriers for biological agents and pesticides.
• These materials offer controllable morphology, high loading capacity, and low toxicity.

Conclusions:

• Silica-chitosan hybrid formulations present a sustainable alternative to synthetic pesticides.
• They can mitigate phytopathogens through direct and indirect plant defense strategies.
• These novel formulations are suitable for integrated pest management platforms.
