Therefore, there is a need for sustainable methods to alleviate plant stress, such as non-thermal plasma. Here we review the role of non-thermal plasma for plant treatment, with focus on the control of viruses, bacteria, fungi and other diseases. We present factors influencing the microbicidal activity of non-thermal plasma. Application of non-thermal plasma for combating abiotic stresses such as drought, metal toxicity, nanoparticles and salinity are discussed. Plasma-generated reactive species trigger the activity of stress-responsive genes in plants. The hypothetical mechanisms involved in triggering the activity of different stress-responsive genes controlling diseases as well as abiotic stresses, are also presented and discussed. The mechanism of plant-plasma interaction is similar to priming, hormesis or adaptive response, and resembles vaccination in animals and humans.
