Callus cultures of Lantana camara L. (family verbenaceae) were induced from leaf and stem explants on Murashige and Skoog medium supplemented with α naphthalene acetic acid (NAA), Indole3-acetic acid (IAA) and 2,4 dichloro-phenoxyacetic acid (2,4-D). Callus cultures (4.04 g dry weight) developed from young leaf and shoot tips on medium containing 2, 4-D (0.02 mg/liter) after 25 days in vitro. Callus extract (1% conc.) showed toxicity to the growth of Salvinia molesta Mitchell after 7 days. The leaves and flowers of this species serve as for a source of allelopathic compounds, both exhibited high potential to act as strong biopesticide and suppressed a number of organism including bacteria, fungi, aquatic and terrestrial weeds in its aqueous leachate/extract in earlier studies. This study high lights the ability of callus of L.camara to produce allelochemicals under in vitroconditions that also exhibited phytotoxicity.
