UJI POTENSI KAYU SECANG (Caesalpinia sappan L.) TERHADAP MORTALITAS ULAT JAGUNG (Spodoptera frugiperda) DI LABORATORIUM

Spodoptera frugiperda is a new pest on maize plants in Indonesia that attacks the leaves and corn cobs. Secang wood has the potential as a vegetable pesticide because it contains active compounds. The purpose of this study was to determine the potency of sappan wood (Caesalpinia sappan L.) on the mortality of corn caterpillar (S. frugiperda) in the laboratory. This study used a completely randomized design (CRD) with 6 (six) treatments which were repeated 4 (four) times. The treatments were P0 (without application of sappan wood), P1 (application of sappan wood 1 g/L of water, P2 (application of sappan wood 2 g/L of water, P3 (application of sappan wood 3 g/L of water), P4 (application of sappan wood 4 g/L water, P5 (application of sappan wood 5 g/L water. The method used includes testing the feed spray method and larva body spray. The results showed that the 5 g/L water treatment showed a mortality percentage of 30% with the feed spray method and 22 ,5% by larva body spray method.
