Abstract
Spodoptera litura or grayak caterpillar is one type of pest that can cause damage to the plant. Plants attacked one of them chili plants. The use of natural insecticides from legetan plants can eradicate grayak worms (Spodoptera litura). Legon leaves contain secondary metabolite compounds including terpenoid, flavonoids, saponins, tannins, steroids, alkaloids, bitter flavors, and essential oils. These compounds have the potential to be a natural insecticide. The purpose of this study was to determine the effectiveness of natural insecticide of legetan extract control the grayak caterpillar (Spodoptera litura) in pepper plant laboratory scale. This research is an experimental research with complete Random Design (RAL) single factor with 4 treatments that are L1 (3%), L2 (9%), L3 (15%), and L4 (21%). Data analysis used is descriptive quantitative by using One Way Anova analysis and Post Hoc Advanced Test by LSD. The results showed that the natural insecticide of leaf extract of 21% (L4) leaves was effective against grayak caterpillar mortality by 60%. While natural insecticide leaf extract of legetan 21% (L4) is effective againts the reduced weight of pepper leaves as armyworm to grayak caterpillar activity by 68,89%.
