Toxicity of sphagneticola trilobata extracts against spodoptera litura larva

Spodoptera litura is one of the polyphagous pests that cause damage to many agricultural commodities. Chemical control method was known as a major method use by farmers. Application of plant-based insecticide is an effort to decrease the negative effects of using synthetic insecticides. Sphagneticola trilobata is a weeds species which has potential to use as plant-based insecticides material. This study aims to determine the toxicity of S. trilobata extract in S. litura , as an effort to obtain alternative control materials that are more environmentally friendly. The material used is the leaves and flowers of S. trilobata extracted using water. The treatment concentration consisted of control, 20 ml / l, 40 ml / l, 60 ml / l, and 80 ml / l which were repeated 5 times. The application method used is the residual method on the leaves. Mortality data were analyzed using probit analysis to obtain a Lethal Concentration 50 (LC50) value. The results showed that flower extract was more toxic compared to leaf extract with LC50 value of 277.5 ml / l.
