Abstract

Tobacco type Prilep P-23 treated with Cineb S-65 was investigated spectrophotometrically for the residues of CS2 and by thin-layer chromatography (TLC) for the residues of ethylenethiourea. The experiment was carried out in the experimental field of Tobacco Institute - Prilep, on a plot of 48 m2. In the period from June 29 to August 21, 1990, a foliar treatment was made in four phases, with a suspension of 18 g Cineb S-65 in 4,51 water. The maximum amount of CS2, residues was recorded on the day of treatment and it decreased gradually during the next two weeks. Investigations showed a lower concentration of CS2 in dry tobacco samples than in fresh leaf. For this reason, it is not recommended to pick up tobacco in the first week of treatment, By TLC after rinsing the tobacco leaves ETU was not detected, but it's presence was detected after l5 min. boiling of the leaves, in a quantity of 5 μg/25 g of tobacco. Bearing in mind that ETU is considered to be cancerous, teratogenic, mutagenic and that it causes aneuploidia. it should be seriously reconsidered whether to apply Cineb S-65, especially in protection of nutrient plants.
