Plants growth regulators in technologies of agricultural crops cultivated on the lands polluted by radionuclides

Expediency of the usage of biologically active substances (BAS) of peat oxidate, maltamine, hydrohumate in technologies of potato, barley and winter wheat cultivation on the territories polluted by radionuclides is shown. Aiming at raising of BAS effectiveness, production profitability, reduction of quantity of technological operations, it is recommended to use BAS in the complex of technological methods of plants protection jointly with tank mixtures and pesticides. In this case significant raising of plants productivity and in some cases reduction of the level of harvest pollution (1,2 - 1,9 times) by radionuclides are achieved
