Effects of MITC Released from Boscia Senegalensis as Biopesticide in Senegalese Seeds with Special Attention to Cowpea: Detection of Residues

Abstract

B. senegalensis leaves and fruits are known to contain glucocapparin which hydrolysis by endogenous myrosinases lead to the release of methylisothiocyanate (MITC). This product is very active against insect stored products by fumigation. This paper reveals that MITC penetrate into seeds during treatment. Multiple Headspace Extraction coupled to GC (MHE-GC) method allowed to evaluate the level of MITC residues sequestrated by exposed seeds to B. senegalensis organs. Furthermore, tests conducted on germination capacity have been demonstrated that MITC doesn’t corrupt the germination capacity of grains.
