Summary:This study was carried out to determine the persistency and safety of emulsifiable concentrate (EC) and wettable powder (WP) formulations of Tephrosia vogelii and Piper aduncum (1:5) against natural enemies and broccoli leaves (phytotoxic effects) as well as to assess their effectiveness against Crocidolomia pavonana in field. EC and WP formulations were safe to parasitoid Eriborus argenteopilosus and did not cause any phytotoxic effects on broccoli leaves. Persistency of EC and WP formulations were lower than bio-insecticide Bacillus thuringiensis (BT) and sythetic pesticide with active ingredient deltametrin. The mortality of C. pavonana treated with EC and WP formulations reached 100%, while BT and deltametrin only reached 73.33% and 88.33% respectively, at the first day treatment. The effectiveness of extracts were declined sharply at one day after treatment indicating low persistence of formulation. In field, EC and WP formulations suppressed the population of C. pavonana more than 80% compared to control. Both formulations showed better activity compared to synthetic insecticide deltametrin.
