THE INFLUENCE OF BIOLOGICAL PREPARATIONS ON THE POTATO STORAGE

The article presents the results of the application of biological preparations at potato storage. It was found that of the biological preparations tested (Risobakt SP and Fitop 8.67) Fitop 8.67 appeared to be the most effective. The lowest percentage of waste tubers was obtained when using this preparation for prestorage treatment of potato. Storage losses of Fitop-8.67-treated potato amounted to 3,6 %, while Risobakt SP showed the loss rate of 5,4 %. Hence, the preparation Risobakt SP appeared to be less effective in comparison with Fitop 8.67. In non-treated tubers the losses amounted to 6,3 %.
