Abstract: If seed of vetch and sugar beet had been treated with benzothiazolium salts, the sugar and chlorophyll contents in leaves increased. Higher sugar contents in the beet-heads, lower contents of potassium, sodium,α-amino acids, and higher yield of sugar beet was found after application of the salts on the leaves of sugar beet. The achievement of these positive results depends on the time of application and on soil and climate conditions. The optimal dose was 50 g ha^-1 . The benzothiazolium salts were found to be a new group of compounds with auxine-like activity.
