This study examined the impact assessment of pyrrolizidine alkaloids isolated from leaf methanolic extract of Heliotropium indicum, for the management of stored grain losses caused by Callosobruchusmaculatus and Sitophilus species. The plant is a member of the genus Heliotropium from the family Boraginaceae. The methanol was used to extract the leaves, and the extract was tested over the course of 24 to 96 h at two different concentrations (0.25 mg/g to 0.5 mg/g). Comparable to standard insecticide (cypermethrin), pure IPM-65 isolate exhibited similar insecticidal activity of 98.33% mortality at 0.5 mg/g 96 h postexposure at (P≤ 0.05) level of significance. Nuclear Magnetic Resonance (NMR) spectroscopy and Liquid chromatography - mass spectrometry (LC-MS) were used to identify the pure IPM-65 isolate as a mixture of pyrrolizidine alkaloids. According to the findings in this study, the pyrrolizidine alkaloid compounds isolated from leaf methanolic extract of Heliotropium indicum showed great promise as a biopesticide for postharvest grain storage management, thereby providing a sustainable substitute for pesticides.
