Fungal attack

A research team at the University of Florida led by Shad Ali and colleagues at the University of Central Florida and the New Jersey Institute of Technology have discovered that silver nanoparticles produced with an extract of the wormwood can kill the fungus phytophthora. This plant pathogen affects more than 400 different species of plant and tree. “The silver nanoparticles are extremely effective in eliminating the fungus in all stages of its life cycle,” Ali said. “In addition, it had no adverse effects on plant growth.” The silver nanoparticles have many ways of inhibiting fungal growth and so there is a greatly reduced chance of resistance emerging in the fungus.
