Abstract

Tobacco is a plant that is concerned with the quality of its leaves, damage to tobacco leaves can reduce its selling value. Caterpillars (Spodoptera litura) are pests in tobacco plants that damage the leaves of tobacco plants. Extraction from parts of the tobacco plant can be used as raw material for vegetable pesticides, extracted chopped tobacco can produce alkaloids which can be used as an insecticide to control caterpillars. The purpose of this study was to obtain the best soaking time for chopped tobacco to control caterpillars. The research was carried out in the laboratory and in fields using tobacco plants as hosts for third instar caterpillar larvae by means of contact poison. The research method used a randomized block design (RBD) with the treatment of chopped tobacco for 12, 24, 36, 48 and 62 hours with five replications. The variables observed were mortality, attack intensity and duration of pupa formation. The results showed that chopped tobacco immersion was effective against army caterpillar mortality, the soaking time of chopped tobacco could also accelerate the formation of pupae and 60 hours of immersion had the best attack intensity.
