ThermoSeed, a method for thermal disinfection of seeds, has been developed in Sweden over approximately 12 years. The method (Forsberg, 2001) is based on the use of precisely controlled hot, humid air, in ways adapted for optimum effect in every individual seed lot. It has been used in cereals on a commercial basis since 2002 as an alternative to chemical seed treatment. In official evaluations, ThermoSeed-treated barley seed has generally given higher yields than seeds treated with conventionally used chemicals.
