A variety of physical treatment methods are able to kill pathogens on and in seeds non-selectively. In all cases, the application of these methods requires optimisation of the relevant treatment parameters such as temperature, treatment time or energy dose. The optimum treatment effect is achieved when the selected parameters induce a maximum reduction of infestation without relevant impairment of germination capacity and plant growth. It has been confirmed that different physical measures can be used for the control of seed-borne pathogens. The “classical” hot water treatment method is suitable for a wide range of seeds. Further procedures like the hot air seed treatment method “Thermoseed®”, the vacuum-steam treatment method Steamlab, and others are also suitable.
