Biological efficacy of a preparation Rastim 30 DKV (auxinoid containing benzolinon: 3-[benzyloxycarbonylmethyl]-benzothiazoline-2-on as an active ingredient) was studied. Biological efficacy consists in changes in tuber number under the hill, in tuber size and weight and it controls qualitative characteristics - contents of dry matter, starch and nitrates. Experimental treatments of two potato varieties involved three ways of regulator application, four concentration sand four doses. Another objective of these experiments was to determine the best application date in the growing season. Benzolinon effects on the number of table tubers and on tuber weight were positive mainly in tubers of 4 to 7 cm size category in both varieties in the three experimental years. Applications to the crop were best in comparison with combined treatment and with seed tuber dipping. The active ingredient Rastim 30 DKV (benzolinon) did not have any significant effects on tuber quality.
