摘　　要：The current paper has elaborated the efficient utilization of liquid biodiesel waste in combination with dillapiole and citronella essential oil as active ingredients.Sawdust,cellulose and hydrophobic silica were used as inert ingredients,which make the tablet to float over the water surface.ATR-FTIR analysis of tablet confirmed the compatibility with citronella oil,dillapiole,liquid biodiesel waste in tablet composition after compression.Physico-chemical analysis studies show that tablet parameters are in standard limits.SEM analysis shows some porous structures in tablet composition which confirms the floating nature of the tablets.The specific ratio(2:2:1)of citronella oil,dillapiole and liquid biodiesel waste showed maximum mortality,i.e.95%after 24 h.After application,the tablet is nontoxic towards the aquatic organisms and water quality remains unaf-fected.The better performance of the tablets has been evaluated in terms of characterization studies,viz.ATR-FTIR and SEM studies and bioefficacy trials which confirmed the presence of active ingredients responsible for insecticidal activity.
