EVALUATION OF THE IMPACT OF WASHING PROCEDURE ON THE THIABENDAZOLE CONCENTRATION IN SOLANUM TUBEROSUM

Abstract

Thiabendazole (2-(1,3-thiazol-4-yl)-1H-benzoimidazole) is a fungicide used to ensure potato stability during storage. That is way it is manly found in stored potatoes. To see the impact of potato washing on Thiabendazole concentration samples from different varieties were extracted using dichlometane and analyzed by HPLC with florescent detection. The samples were analyses before and after the washing operation. The potatoes were washed using the CALIPSO Root Washing Module in which the washing procedure is done in the washing drum and on ramp witch has nozzles for additional washing. The levels of Thiabendazole found in the samples before washing were low. There was a decrease of 42 % of the Thiabendazole concentration in all samples after washing.
