Abstract

Toksisitas formulasi insektisidafipronil, deltametrin, profenofos, abamektin, Ba cil lus thuringiensis subsp./var.kurstaki strain EG 7841 (crymax WDG) dan B. thuringiensis subsp./var. kurstaki strain HD-7 (dipel WP) diuji dilaboratorium terhadap lima strain lapangan larva Plutella xylostella (L.) yang berasal dari pusat pertanaman kubis diLembang, Pangalengan, Kejajar/Dieng, Batu, dan Berastagi mulai bulan Sep tem ber 2000 sampai dengan Februari2001. Pengujian menggunakan metode pencelupan potongan daun kubis ke dalam tiap larutan insektisida ujikemudian larva P. xylostella instar 2 dan atau 3 diletakkan pada potongan daun kubis tersebut. Penghitungan nilaiLC50 tiap jenis insektisida yang diuji dilakukan menggunakan pro gram komputer analisis probit. Hasil penelitianmenunjukkan, terdapat perbedaan kerentanan P. xylostella, tergantung pada asal (strain) P. xylostella. Berdasarkannilai LC50 insektisida uji, pada umumnya P. xylostella strain Lembang, Pangalengan, Kejajar/Dieng, dan Batu sangatresisten terhadap deltametrin dan profenofos kecuali strain Berastagi tidak diketahui. Semua strain P. xylostella(Lembang, Pangalengan, Kejajar/Dieng, Batu, dan Berastagi) rentan terhadap fipronil dan B. thuringiensis subsp./varkurstaki strain EG 7841. Plutella xylostella strain Lembang, Pangalengan, dan Berastagi sangat resisten terhadap B.thuringiensis subsp./var. kurstaki strain HD-7, sedang P. xylostella strain Kejajar/Dieng dan Batu agak resistenterhadap abamektin. Berdasarkan hasil penelitian ini terbukti, bahwa pemantauan perkembangan resistensi P.xylostella terhadap jenis insektisida yang umum digunakan oleh petani kubis sangat penting dilakukan secara rutin.Hasil penelitian ini juga berguna untuk menyusun data dasar LC50 dan strategi pengelolaan resistensi insektisida.AB STRACT.

Abstract

Percobaan lapangan menggunakan metode perbandingan perlakuan berpasangan telah dilaksanakan di Desa BojongNagara, Kecamatan Ciledug, Kabupaten Cirebon, Jawa Barat (± 5 m dpl), dari bulan Juni sampai Desember 2002.Percobaan ini bertujuan untuk mengetahui kelayakan teknis dan ekonomis penerapan teknologi pengendalian hamaterpadu (PHT) yang dihasilkan oleh Balai Penelitian Tanaman Sayuran dibandingkan dengan teknologi yang umumdigunakan oleh petani. Tiap perlakuan diulang empat kali, dengan ukuran petak perlakuan adalah 5 x 20 m = 100 m2.Hasil penelitian menunjukkan bahwa penerapan rakitan komponen teknologi PHT pada bawang merah dan cabai yangdihasilkan oleh Balai Penelitian Tanaman Sayuran secara ekonomi lebih menguntungkan dibandingkan dengansistem petani, karena nilai nisbah R/C di petak PHT sebesar 1,47 sedangkan nilai nisbah R/C di petak petani sebesar0,84. Secara ekologi, penerapan PHT pada sistem tanam tumpanggilir bawang merah dan cabai lebih menguntungkankarena dapat menekan penggunaan insektisida dan fungisida masing-masing sebesar 61,53 dan 100% pada tanamanbawang merah dan 72,72 dan 90,90% pada tanaman cabai, sehingga residu insektisida di dalam tanah menurunsebesar 23,06% inhibisi dan fungisida menurun sebesar 50,72% inhibisi, sedangkan di petak petani residu insektisidadi dalam tanah meningkat sebesar 8,14% inhibisi dan fungisida menurun sebesar 20,37% inhibisi. Sementara populasipred a tor di petak PHT lebih tinggi (11,54-55,55%) dibandingkan dengan populasinya di petak petani. Populasi agenshayati, yakni Bacillus sp. dan Trichoderma sp. pada petak PHT lebih tinggi, masing-masing sebesar 35,31 dan 58,35%dibandingkan populasi di petak petani. Residu insektisida dan fungisida pada hasil panen bawang merah dan cabai dipetak PHT masih di bawah ambang batas yang diijinkan, sedangkan residu pada hasil panen bawang merah dan cabaipada petak petani berada di atas ambang batas yang diijinkan.AB STRACT.
