UJI EFEKTIVITAS BEBERAPA KONSENTRASI EKSTRAK DAUN KETAPANG (Terminalia catappa L.) TERHADAP ULAT GRAYAK (Spodoptera litura) SECARA IN VITRO

Spodoptera litura is one of the important plant pests that are polyphagic. attacks can cause damage to up 80% on plants causing losses for framer. Control using synthetic pesticides excessive because it causes negative environment. Efforts be made biopesticides such as Terminalia catappa L. leaves. This research aims obtain effective concentrations in controlling vitro. The was carried out Pathology, Entomology and Microbiology, Faculty Agriculture Animal Husbandry experimental farm State Islamic University Sultan Syarif Kasim from February March 2019. used a Completely Randomized Design with 5 treatments, consisting control, 9% EDK, 18% 27% EDk 36% EDK 3 replications. parameters larvae stop eating (%), speed death, mortality, toxicity LC50 become pupae (%). result showed concentration 18%.
