The present study to investigation evaluates the antimicrobial and larvicidal activity of extract of Dieffenbachia picta. Antimicrobial and larvicidal activity were carried out of different concentration of the extract. The solvent methanol, chloroform, and petroleum ether were used for extraction. Antimicrobial activity was found to be highly effective in methanol extract. The fungal isolated tested include: Epidermatophyton flaccosum, Microsporum gypseum, and Trichophyton mentagrophytes, Candida albicans. The bacterial isolated tested include: Eschrichia coli, staphylococcus aureus, Streptococus viridians, Vibrio cholera. The zone of inhibition was measured and tabulated. The petroleum ether extract of the D.picta was the most effective and exhibited the highest mortality rate of 100% at a concentration of 1.00 µg/ml in 4th instar larvae of Culex quinequefaciatus.
