ABSTRAK

Attack of Aphis gossypii is one of constraints in cultivating of patchouli plant. An experiment with the purpose to examine the effectiveness of botanical insecticides to A. gossypii on patchouli plant. The experiment was carried out in Research Station of Indonesian Spice and Medicinal Crops Research Institute, at Cicurug, Sukabumi from June to October 2011. The experiment was arranged in a Randomized Block Design, nine treatments and three replications. The treatments were mixing of neem oil + soap nuts, neem oil + clove oil, neem oil + citronellal oil, neem oil + clove oil + citronellal oil, citronellal oil, clove oil, neem extract, carbosulfan, and control. Patchouli plants were planted with spacing of 40 cm x 60 cm. The number of plant population plot-1 was 25 plants and the number of sample plot-1 for observation was five plants. Sampling of observed plants was conducted diagonally. Observation was carried out by counting population of A. gossypii on one shoot. Application of insecticides was conducted one day after the first observation. Interval of application was every week, conducted eight times. Other parameters observed were plant height and production of patchouli. Results showed that all treatments of botanical insecticides were effective to decrease of A. gossypiipopulation. The most effective treatment was that of neem extract with the value of  efficacy was more than 80% occurred at seven assessments. Plant high between treatment is not significant different.

ABSTRAK

Serangan kutudaun Aphis gossypii merupakan salah satu kendala dalam usaha budidaya nilam. Penelitian yang bertujuan untuk menguji efektivitas insektisida nabati terhadap A. gossypii pada tanaman nilam. Penelitian dilakukan di Kebun Percobaan Balai Penelitian Tanaman Rempah dan Obat (Balittro) di Cicurug, Sukabumi sejak Juni sampai Oktober 2011. Penelitian menggunakan Rancangan Acak Kelompok, dengan sembilan perlakuan dan tiga ulangan. Sebagai perlakuan ialah campuran (1) minyak mimba + rerak, (2) minyak mimba + minyak cengkeh, (3) minyak mimba + minyak seraiwangi, (4) minyak mimba + minyak cengkeh + minyak seraiwangi, (5) minyak seraiwangi, (6) minyak cengkeh, (7) ekstrak mimba, (8) karbosulfan (insektisida sintetis), dan (9) kontrol. Tanaman nilam ditanam dengan jarak tanam 40 cm x 60 cm. Jumlah populasi tanaman per petak adalah 25 tanaman dan jumlah sampel per petak adalah lima tanaman. Pengambilan sampel tanaman yang diamati dilakukan dengan sistem diagonal. Pengamatan dilakukan dengan cara menghitung populasi A. gossypii pada satu pucuk yang terserang. Aplikasi insektisida dilakukan satu hari setelah pengamatan pertama. Interval aplikasi adalah satu minggu, dilakukan sebanyak delapan kali. Parameter lain yang diamati ialah tinggi tanaman dan produksi nilam. Hasil penelitian menunjukkan bahwa semua perlakuan insektisida nabati efektif menurunkan populasi A. gossypii. Insektisida nabati yang paling efektif mengendalikan A. gossypii adalah perlakuan ekstrak mimba dengan nilai efikasi lebih dari 80% dan terjadi pada tujuh kali pengamatan.Tinggi tanaman diantara perlakuan tidak berbeda nyata.
