Abstract

An apparatus and process for the disinfection of seeds, preferably those of grains, to prevent pathogenic organisms from being planted with the seeds, and to provide reliable disinfection without using toxic agents. The seed is irradiated by low-energy electrons with energy and dosage controlled so that the surface and regions close to the surface are exposed to the radiation with fungicidal effect. A beam of the low-energy electrons is provided by an electron gun aimed at a region within a seed-receiving chamber at which the seeds to be irradiated are caused to intercept the radiation repeatedly and on all sides. The chamber may be at atmospheric pressure or be evacuated, the latter condition requiring vacuum locks at seed inlet and outlet ports of the chamber.
