Abstract

The rapid test method developed for Ethylenebisdithiocarbamate (EBDC) Fungicide based on carbon disulfide evolution was evaluated by determining its accuracy, sensitivity and efficiency. The recovery is 90.58 - 92.03% and 75i - 83% using spectrophotometric method and color chart, respectively and sensitivity is 0.01 ppm. The accuracy was evaluated in terms of absolute error. The concentration of EBDC Fungicide residues in pechay planted in open field and those under unexposed condition were monitored using the rapid test method. The method was also used in the detection of EBDC Fungicide in various market samples (pechay, cabbage, tomato and Baguio beans). The EBDC residues in pechay placed in open field persisted for only 7 days while pechay plants under unexposed conditions persisted for 17 days. EBDC residues were not detected in samples of tomato, cabbage and Baguio beans. However, 8; or the pechay samples were found to contain EBDC residues that have concentrations below the MRL set by Food & Agriculture Organization/ World Health Organization (FAO/WHO).
