Abstract
The objective of this study was to make formulation of mixed extracts of Tephrosia vogelii and Piper aduncum in the form of emulsifiable concentrate (EC) and wettable powder (WP), which had insecticidal activity against C. pavonana cabbage pest. The rasio of T. vogelii and P. aduncum was 1:5 which was stable in water distillation and hard water. EC and WP formulations have insecticidal activity against C. pavonana with LC50 and LC95 of EC formulation were 0.15% and 0.13% and WP formulation 0.35% and 0.31% respectively. Besides causing the mortality of C. pavonana, EC and WP formulations inhibited the development of treatment larvae. The inhibition development of larval from second to third instar approximately2.31 days, and the third to fourth instar 2.38 days compared to control. Residue of EC and WP formulations killed 100% C. pavonana at first day treatment, but Formulations persistence were significantly decreased on the second and third days after treatment. The addition of sunscreen ingredients did not affect the extract persistence on broccoli leaves.
