STUDY OF FUNGICIDE RESIDUES IN THE GRAIN OF FUNGICIDE-TREATED WHEATS - I - CYPROCONAZOLE-BASED AND CARBENDAZIME-BASED FUNGICIDES

The aim of the present study was to detect the fungicide residues (cyp roconazole and carbendazime) in flour and bran, produced from grain of 4 fungicide-treated wheats by gas and liquid chromatography. In case Alto 320 was applied in the 1-2-nodes stage of the stem development cy proconazole could be detected in the flour of only two wheat varieties , but in the bran it was not detected at all. When Alto 320 was spraye d in stage closer to harvesting (in the beginning of heading) - cyproc onazole could be detected in the flour of all four varieties and in th e bran of three varieties. In case of Alto Combi 420 treatment cyproco nazole was detected only in the flour of one wheat variety, carbendazi me has not been found in any of the samples. The results show that fun gicides of triazole type are more pronouncedly translocated in flour ( 7 cases) as compared to bran, which is constituted mainly from parts o f the pericarp (3 cases).
