Fighting Phytopathogens with Engineered Inorganic-Based Nanoparticles.

Area of Science:

• Agricultural Science
• Materials Science
• Environmental Science

Background:

• Developing effective and eco-friendly agrochemicals (bactericides, fungicides, insecticides, nematicides) is a significant challenge.
• Nanotechnology offers novel solutions for anti-phytopathogenic agents using nanomaterials.
• Inorganic-based nanoparticles (INPs) are promising due to their antimicrobial mechanisms against plant pathogens.

Purpose of the Study:

• To review recent advances in engineered inorganic-based nanoparticles (INPs) for agricultural applications.
• To identify INPs with antimicrobial activity and assess their phytotoxicity.
• To explore the effectiveness of INPs against various plant-pathogenic microbes (bacteria, fungi, viruses).

Main Methods:

• Review of scientific literature on engineered inorganic-based nanoparticles (INPs).
• Analysis of studies characterizing INPs (size, shape, composition, surface features).
• Evaluation of reported antimicrobial activity and phytotoxicity data for various INPs.

Main Results:

• Engineered INPs demonstrate diverse mechanisms for targeting and killing microbes.
• Specific INPs show promising reactivity against bacteria, fungi, and viruses.
• Some INPs exhibit antimicrobial effects with minimal or no phytotoxicity.

Conclusions:

• Inorganic-based nanoparticles (INPs) represent a viable alternative to conventional chemical agrochemicals.
• Further research is needed to precisely characterize INPs for optimal plant disease management.
• INPs offer a pathway to developing sustainable and effective strategies for plant protection.
