Abstract

Penelitian ini bertujuan untuk mengetahui ketahanan beberapa aksesi tembakau cerutu (Nicotiana tabacum L.) terhadap penyakit Cucumber Mosaic Virus (CMV) Penelitian dilaksanakan di Laboratorium dan Rumah Kasa Fitopatologi Balai Penelitian Tanaman Tembakau dan Serat Malang, mulai bulan Mei sampai dengan Oktober tahun 2006. Rancangan percobaan disusun dalam Rancangan Acak Lengkap (RAL) dengan tiga ulangan. Perlakuan terdiri dari 30 aksesi tembakau cerutu termasuk tanaman kontrol. Unit perlakuan 10 tanaman tiap aksesi. Parameter pengamatan dengan menghitung luas serangan, intensitas serangan dan persentase daun yang terserang pertanaman. Inokulasi dilakukan pada umur dua minggu setelah tanam pada tiga helai daun bagian atas yang telah membuka secara mekanis setelah ditaburi carborundum 600 mess. Ekstrak daun tembakau yang sakit dalam buffer fosfat pH 7 dioleskan secara merata menggunakan kapas steril. Pengamatan dilakukan satu minggu setelah inokulasi dengan interval satu minggu. Hasil evaluasi menunjukkan ketahanan aksesi tembakau cerutu terhadap penyakit CMV diperoleh : dua aksesi sangat tahan yaitu S.2234 dan S.2398 dengan rata-rata luas serangan 0,00%.

Abstract

This study was conducted for tenth month in laboratory and greenhouse of Plant protectionDepartment of Agriculture Faculty Jember university. This research was coonducted by two step invitro including identification and screening in laboratory,and in vivo including induce systemicresistant and leaf interaction of antagonist against patogen. The result show that activities offluorescent pseudomonad in vitro against C. nicotianae was by production antibiotic, proteases andsiderophore. Antagonistic invitro was effective under 20-30OC temperatures. Influence of ironconcentration at 5, 50 and 100 μM was affect on antagonist by siderophore, more high concentrationless ability to suppress C. nicotianae growth. In greenhouse test, all isolate was shown ability tocontrol C. nicotianae by induce plant resistant and by antibiosis activities.

Abstract

Pemanfaatan T. harzianum sebagai agens hayati dalam skala luas belum banyak dilakukan, salah satukendalanya adalah terbatasnya agens hayati isolat lokal yang diproduksi secara massal. Oleh karenaitu diperlukan teknologi untuk produksi massal T. harzianum yang murah dan mudah dilakukan.penelitian ini dilakukan untuk membandingkan perbanyakan T. harzianum pada beberapa media cairekstrak kentang, ekstrak beras, ekstrak jagung muda dan air kelapa muda dengan menggunakan alatFermentor Sangat Sederhana (FSS) dengan media organik limbah pertanian yaitu sekam, bekatul danserbuk gergaji. isolat Ralstonia solanacearum hasil isolasi di daerah Malang mempunyai virulensiyang tinggi. Hasil ekplorasi agensia hayati bakteri Pseudomonad fluoresen diperoleh 130 isolat. Dari130 isolat tidak semua mampu menghambat bakteri Ralstonia solanacearum. Ada 37 isolat yangberpotensi sebagai agensia hayati terpilih dengan zona hambatan terbesar dengan mekanismeberagam yaitu bakteriostatik dan bakterisida

Abstract

Eggs of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) on its host plants could beparasitized by some species of parasitoids, especially of the genus Trichogrammatoidea andTrichogramma. This research was aimed to study the population dynamics of egg parasitoids of H.armigera on unsprayed fields of cotton monoculture and intercropped with maize. The plot size ofeach field was 19 m x 20 m, with five replicates. We collected H. armigera eggs from both fieldsperiodically since 23 days after planting (dap) to 100 dap. The eggs were collected on 9 sample units(size of sample unit: 1 m2) in 7-days interval. The number of collected and parasitized eggs wasrecorded and the emerged parasitoids were identified to species level. The result showed that thefluctuation pattern of H. armigera egg population was not different on cotton monoculture and cottonintercropped with maize. The parasitoid population was relatively high during the flowering phase ofcotton and maize. The parasitoids of H. armigera eggs found in cotton monoculture and cottonintercropped with maize were T’toidea armigera, T’toidea guamensis, T’toidea bactrae bactrae,T’toidea bactrae fumata, T. chilonis and T. chilotraeae . The dominant species on early season untilthe flowering phase of the plants was T’toidea armigera, while on the latter phase of the plantphenology was T. chilotraeae. Implication of this population dynamics and the succession of theparasitoids in biological control are discussed.

Abstract

Liriomyza huidobrensis Blanchard was originally described in Argentina and has now been found worldwide. In Indonesia, this species was first recorded on potato in 1994 in Bogor, West Java. The failure of quarantine procedure is blamed for introduction of LMF worldwide. In most cases, cultivation of vegetables such as potato as a cash crop has relied heavily on the use of pesticides, often excessively so with growers frequently spraying on a calendar basis, irrespective of the level of the pest population. Surveys have been conducted on vegetables farmers in the Bromo highlands region of East Java, Indonesia on the perceived importance of L. huidobrensis and the control methods adopted. the results of the survey suggested that LMF infestation in the Bromo Highlands Region has become a very serious problem, almost certainly due to the misuse of insecticides

Abstract

Corn is the important food and crop for Indonesian. Recently, production of corn decreased because ofthe pest (Helicoverpa sp.). Until now, the control of Helicoverpa sp. depend on the using of chemicalelement. However, effect of synthetic chemical element usage was the appearance of secondary pest,the death of useful insect and the high accumulation of pesticide residue both in biotic and abioticagroecosystem. The residue of pesticide should effect on human health and environment balance.Furthermore, the control method using biological agents that have pathogenicity to host was done..One of biological agents is entomopathogenic nematodes. Entomopathogenic nematodes can kill it’shost at 24-72 hours, have wide host range such as Lepidoptera, Coleoptera, Diptera and Hymenopteraorder, and have no negatif effect on environment. The aim of the research is to find nematodes asbiological agents that effective against pest of corn (Helicoverpa sp.). The research was done inlaboratory of HPT UPN ”Veteran” Jawa Timur and HPT University of Jember. Methods of theresearch were : 1) Isolating entomopathogenic nematodes from many endemic area of Helicoverpaspp. In East Java; 2) Identificating Entomopatogenic Nematodes; 3) Screening IsolatesEntomopathogenic nematodes from East Java. The result indicated that there was anEntomopathogenic Nematodes Isolate from Tulungagung that has the highest pathogenicity (100%).

Abstract

Helicoverpa armigera merupakan hama utama tanaman tomat karena mampu menurunkan produksi tanaman. Pada umumnya petani menggunakan pestisida kimia sintetik untuk mengendalikan hama ini tetapi penggunaan yang kurang bijaksana akan mencemari lingkungan dan produk budidaya. Salah satu alternatif pengendalian hama yang memperhatikan keamanan lingkungan adalah dengan memanfaatkan agens hayati. Penelitian ini bertujuan untuk mengkaji potensi Bacillus thuringiensis, Beauveria bassiana dan Steinernema carpocapsae sebagai pengendali hayati hama penggerek buah tomat dalam upaya mempertahankan produktivitas tanaman tomat. Perlakuan berupa paket pengendalian hama terdiri atas : Bacillus thuringiensis dengan konsentrasi 2 gram/liter; Beauveria bassiana dengan konsentrasi 0,2 gram/liter (kerapatan spora 109); Steinernema carpocapsae dengan konsentrasi 1.000.000 IJs/liter; Insektisida (bahan aktif profenofos) dengan konsentrasi 2 gram/liter dan kontrol. Berdasar hasil penelitian dapat disimpulkan bahwa : (1) Agens hayati berupa bakteri Bacillus thuringiensis, jamur Beauveria bassiana dan nematoda Steinernema carpocapsae dapat dimanfaatkan sebagai pengendali penggerek buah tomat (H. armigera), (2) B. thuringiensis lebih mampu menekan populasi hama dan menekan kerusakan tanaman dibandingkan dengan agens hayati lain, (3) B. bassiana lebih cenderung spesifik inang sehingga lebih mampu untuk menekan populasi dan kerusakan buah yang disebabkan oleh H. armigera, (4) S. carpocapsae kurang mampu menurunkan intensitas kerusakan buah H. armigera karena perilaku H. armigera yang pasif dan masuk kedalam buah tomat memperkecil kemungkinan infeksi dan (5) Aplikasi pengendali hayati masih mampu mempertahankan jumlah buah yang sehat dan lebih menekan kerusakan buah tomat.
