Abstract :

Over the last decade the phasing-out of methyl bromide has brought out the need for alternative strategies for the management of soilborne pests and diseases in to sharp focus. Among the different alternative control methods being touted to replace methyl bromide are the use of other fumigant-like pesticides such as the methyl isothiocyanate generator metam sodium, 1,3-dichloropropene (1,3-D), chloropicrin, or mixtures of these, and various biologically-based options. The attention for bioactive natural molecules has been strongly augmented because public opinion considers them as a mild, safe and reliable option to prevent or to fight several human, animal and plant diseases. Among several bioactive molecules, glucosinolates (GSLs) from Brassicaceae and their enzymatic degradation products especially isothiocyanates (ITCs) via myrosinase as biofumigant stands out as a promising alternative for the management of a variety of pests including weeds, insects and plant pathogens as reported through several researches. However, there are issues such as dose validation, response of other beneficial microbes in the soil to these molecules, etc. which needs to be further addressed
