Hasil yang diperoleh menunjukkan bahwa formulasi campuran ekstrak aman terhadap parasitoid Eriborus argenteopilosus dan tidak menyebabkan fitotoksik terhadap daun brokoli. Persistensi formulasi sangat rendah, meskipun demikian aktivitas insektisida formulasi EC dan WP lebih tinggi jika dibandingkan insektisida berbahan aktif Bacillus thuringiensis BT. Formulasi EC dan WP tidak menimbulkan gejala fitotoksik pada daun brokoli sehingga aman digunakan di lapangan. Aplikasi di lapangan menunjukkan bahwa pada saat populasi hama C. pavonana tinggi, formulasi EC dan WP mampu menekan populasi hama C. pavonana lebih dari 80 jika dibandingkan dengan kontrol, bahkan aktivitas kedua formulasi lebih baik jika dibandingkan dengan insektisida pembanding deltametrin Kata kunci: Eriborus argenteopilosus, fitotoksik, lapangan, parasitoid, persistensi Abstract The aims of this study were 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 effect, and to assess their effectiveness against Crocidolomia pavonana in the field. EC and WP formulations were safe to parasitoid Eriborus argenteopilosus and did not cause phytotoxic effect on broccoli leaves. Persistency of EC and WP formulations was lower than bioinsecticide Bacillus thuringiensis BT. The mortality percentages of C. pavonana which were applied with EC and WP formulations reached 100, while BT was only 73.33, at first day treatments. Extract effectiveness declined sharply at one day after treatment, indicating the low persistence of formulations. EC and WP formulation did not cause phytotoxic symptoms on broccoli leaves. Field applications showed that at high population of C. pavonana, the EC and WP formulations were able to suppress the population of C. pavonana more than 80 compared to the control. The activity of both formulations showed better activity than deltametrin, as a comparator synthetic insecticide. Keywords: Eriborus argenteopilosus, field, parasitoids, persistence, phytotoxic
