Direct synthesis of lemongrass essential oilsilver nanoparticles (EO-AgNPs) as biopesticides and application for lichen inhibition on stones.

Lemongrass essential oil is used directly to kill lichens and has many disadvantages such as being less effective, volatile, and inefficient. Lichens are a type of microbe that grows in rocks and cause biodeteriorations of rock material because they are highly erosive. Therefore, this research aims to investigate the direct synthesis of lemongrass essential oil-silver nanoparticles (EO-AgNPs) as biopesticides and application for lichens inhibition on stones.
