Abstract

Bioinsecticide formulation conducted by adjuvant addition to improve its effecetiveness in the application. Its addition was only help to work whereas active compound and ingredient as a main core originated from plant simplicia. This research was utilized bintaro (Cerbera odollam) as simplicia. It already began to use it as bioinsecticide against armyworm (Spodoptera litura F) even formulation approachment was not conducted in mustard (Brassica rapa) in previous research. Mustard commodity commonly measured based on leaves performences, when its performance broke by pest such as armyworm might decline the commercial value. So this research aimed to determine the effectiveness of liquid biopesticide formulation of the active ingredient from bintaro (Cerbera odollam) leaf extract in pressing the attack larvae of S. litura F. Larvae deployed in mustard leaves (16 HST). Liquid bioinsecticide concentration formulated in 30%, 40%, 50%, 60%, and 70%. Spraying method used to against S. litura F. consisted on preventive (15 HST) and curative (17 HST). Leaves damage observation conducted at day - 35th (HST). The result showed the formulation suppressed larvae from 40% concentration in preventive way 15 HST and 60% concentration as curative way at 17 HST.
