The present invention relates to the treatment of plant material, especially seeds. The method uses vacuum pressure for disinfecting seeds from pathogens. Seed disinfection is important as seeds infected by pathogens could propagate them and lead to high losses of the crops. The method is applicable to seeds from cucurbit species specifically watermelon, melon, squash, pumpkin, cucumber and gourds but also seeds from solanaceous species specifically tomatoes, peppers and eggplants.
