Studied effect of prelanding processing of tubers thermal shock (37˚С, 39˚С, 45˚С, 1 hour) and 1мМ a solution iodoacetic acid sodium salt (МIА) on potato vegetation in field conditions. In experiments used preliminary infected with the activator of ring decay tubers of a potato which landed in the vegetative vessels, not infected tubers landed in the field. It is revealed that at the infected potato of a susceptible grade prelanding processing of tubers by a hyperthermia 37 and 39˚С strengthened symptoms of disease of ring decay, and at processing 45˚С disease symptoms weren't shown. Prelanding processing of tubers 1мМ water solution МИА raised efficiency of a potato in field conditions of cultivation.
