Pepper anthracnose caused by Colletotrichum species is one of the most important limiting factors for pepper production in Korea, its management being strongly dependent on chemicals. The aim of this work was to evaluate the possibilities of using silver nanoparticles instead of commercial fungicides. In this study, we evaluated the effect of silver nanoparticles against pepper anthracnose unde...

Controllable silver nanoparticles were developed by a green approach using extracts of both leaves and bark of Limonia acidissima tree. Due to the presence of phytochemical compounds in L. acidissima leaves and bark; such as saponins, phenolic compounds, phytosterols, and quinines present in extracts act as reductants, hence the silver nanoparticles were easily produced under mild conditions. T...

Silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. A simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  The present study aimed at the comparative study of silver nanopartic...
