Microbe-mediated nanoparticle intervention for the management of plant diseases

Abstract

Plant diseases are caused by various pathogenic microorganisms, leading to substantial economic losses and food insecurity worldwide. However, the extensive use of chemical-based nanopesticides has adverse effects on plants, soil, and environmental systems. There is increasing interest in developing eco-friendly and sustainable alternatives to manage plant diseases. Recently, microbe-mediated nanoparticles (NPs) as nanopesticides have attracted the interest of cultivators, specifically in plant disease management, compared to traditional physical and chemical approaches. This review focuses on the state-of-the-art formulations of nanopesticides by using microorganisms against bacterial and fungal phytopathogens. The article discusses the various mechanisms through which these microbes contribute to the enhanced effectiveness of NPs, including the production of bioactive compounds, improved nanoparticle synthesis, and the facilitation of targeted delivery. The review also highlights the advantages of using microbe-mediated nanopesticides, such as reduced environmental toxicity, increased biodegradability, and the potential to manage pesticide-resistant pathogens. Overall, the use of microbe-mediated NPs is an inexpensive, reliable, and eco-friendly approach for plant disease management.

Suppression of Root Rot Fungal Diseases in Common Beans (Phaseolus vulgaris L.) through the Application of Biologically Synthesized Silver Nanoparticles

“…Therefore, there is a need for alternative control methods to fight these diseases and limit their spread and damage. Recently, nanoparticles have attracted the attention of many scientists working in a variety of disciplines, including those in the agricultural sector interested in plant disease suppression due to their unique properties [ 17 , 18 , 19 ]. Many of them have observed that silver nanoparticles (AgNPs) have a distinct role against a wide range of microorganisms, such as viruses, bacteria, and fungi, which infect and damage plants [ 20 , 21 , 22 , 23 , 24 ].…”
