Method of disinfecting seed

摘要

The invention relates to a method of disinfecting seed, wherein the seed is treated with ozonic gas. Preferably the seed is treated while it is dry and at ambient temperature. It is especially favourable if the seed previous to treatment is placed into vacuum, usually for 2-40, the vacuum pressure generally being 2-40 mm Hg. As a rule the ozonic gas is air. The ozonic gas contains per litre 100-200 p.p.m. of ozone. Treatment with the ozonic gas lasts 2-40 minutes. It is also possible to treat the seed with the ozonic gas while it is suspended in water.
