Influence of the Hyperthermia and Iodoacetic Acid Sodium Salt on Development of Symptoms of Ring Decay and Vegetation of the Potato which has been Grown up Under Natural Conditions

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.
