Reactive Oxygen Species (ROS) participate in a variety of biochemical processes by acting as signaling molecules for cell proliferation and differentiation, immune response, senescence, and other biochemical processes. High concentrations of ROS induce cell death in bacterial and fungal colonies.<br/>Cold plasma generates a variety of reactive neutral species, charged species, and radiation at ambient pressure and room temperature. This chemistry has been applied to a number of biological and agricultural applications.<br/>We have been comparing the effects of ROS and RNS (Reactive Nitrogen Species) generated from liquid solution (Hydrogen peroxide, Nitric acid) to those from a cold plasma source on fungal spores and mature fungal cultures. Preliminary results show a concentration and power dependence on fungicidal and sporicidal efficacy on <i>Botrytis cinerea</i>.
