Seeds are treated in a cold plasma in a reaction chamber to etch the surface of the seeds to remove surface materials, such as fungicides and insecticides, or to disinfect the surfaces. The cold plasma process is carried out using etch gases which do not harm the seeds and for selected periods of time sufficient to remove surface materials without necessarily affecting the viability of live seeds after treatment. Tumbling the seeds while exposing the seeds to the plasma allows the surfaces of the seeds to be etched uniformly.
