| Abstract: | The
scientists at Mexico isolated allyl, benzyl, 2-phenylethyl and phenyl
isothiocyanates in a ratio of 1:3.5:5.3:9.6, respectively, in cabbage leaves
through solid phase microextraction and gas chromatography–mass spectrometry.
The same proportion was used to prepare an isothiocyanate mixture from reagent
grade isothiocyanates (MCIT) to test the effect on Alternaria alternata
growth in vitro. Application of 0.28 and 0.56 mg/ml of MITC, with or
without packing in low density polyethylene bags (LDPE), were also tested on
bell pepper fruit inoculated with A. alternata, using a commercial
fungicide as positive control. A concentration of 0.03 mg/ml of MITC inhibited 100% Alternaria growth in vitro. A treatment with 0.56 mg/ml of MCIT with LDPE bags performed better than the commercial fungicide to control
fungi rot on bell pepper with no adverse effects on fruit quality. MCIT combined
with LDPE bag showed potential to control Alternaria rot on bell pepper
