Abstract

Cocoa pod borer (CPB), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) is a major pest of cocoa. Detection of the pest infestation using sex pheromone traps in the early growth and development of cocoa pods is important for an early warning system programme. In order to prevent the pest infestation the young pods were wrapped with plastic bags. A research to study the CPB incidence was conducted at cocoa plantations in Banjarharjo and Banjaroya villages, District of Kalibawang; Hargotirto and Hargowilis villages, District of Kokap; and Pagerharjo village, District of Samigaluh, Yogyakarta. The experiments design used RCBD with four treatments (sex pheromone trap, combination of sex pheromone trap and pod wrapping, pod wrapping, and control) and five replications. As many as 6 units/ha pheromone traps were installed with a distance of 40 m in between. Results showed that one month prior to the trap installation in the experimental plots there were ripen cocoa pods as many as 9-13%, which were mostly infested by CPB. During the time period of introducting research on August to Desember 2016 there was not rambutan fruits as the CPB host, hence the CPB resource was from infested cocoa pods. The CPB moth trapped as many as 0−7 (1.13 ± 0.14) moths/6 traps/12 observations. The seed damage due to CPB larvae in the pheromone trap treatments (23.98%) was relatively similar with the control (20.25%). Seed damage rate in combination treatment of pheromone trap and pod wrapping (0.59%) was relatively the same with the pod wrapping (0.20%). The pheromone trap was more usefull for monitoring tool rather than for control, meanwhile pod wrapping was an effective control measure of CPB. IntisariPenggerek Buah Kakao (PBK), Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae) merupakan salah satu hama utama kakao. Deteksi serangan hama PBK dengan perangkap feromon seks pada awal pertumbuhan dan perkembangan buah kakao penting dilakukan sebagai sistem peringatan dini. Dalam upaya pencegahan serangan hama tersebut dilakukan pembrongsongan buah muda. Penelitian dilakukan di kebun kakao rakyat di Desa Banjarharjo dan Banjaroya, Kecamatan Kalibawang, Desa Hargotirto dan Hargowilis, Kecamatan Kokap, serta kebun PT Pagilaran di Desa Pagerharjo, Kecamatan Samigaluh, Yogyakarta. Percobaan dengan empat perlakuan (perangkap feromon, kombinasi perangkap feromon dan brongsong, brongsong, kontrol) dan lima ulangan menggunakan rancangan RCBD. Perangkap feromon sebanyak 6 unit/ha dipasang dengan jarak antar perangkap sekitar 40 m. Hasil percobaan menunjukkan bahwa satu bulan sebelum pemasangan perangkap terdapat buah tua sebanyak 9−13 % dan umumnya terserang PBK. Selama kajian berlangsung tidak terdapat buah rambutan sebagai inang PBK sehingga sumber PBK diduga hanya dari buah kakao yang terserang. Ngengat PBK yang tertangkap yaitu sebanyak 0−7 (1,13±0,14) ekor/6 perangkap/12 pengamatan. Intensitas kerusakan biji akibat ulat PBK pada perlakuan perangkap feromon (23,98%) relatif sama dengan kontrol (20,25%). Kerusakan biji kakao pada perlakuan kombinasi perangkap feromon dan pembrongsongan (0,59%) relatif sama dengan pembrongsongan saja (0,20%). Perangkap feromon lebih berfungsi sebagai alat monitoring daripada alat pengendalian PBK, sedangkan pembrongsongan buah merupakan teknologi pengendalian PBK yang efektif.

Abstract

Ginger is one of the spices and medicinal commodities which is cultivated in Indonesia. One of the obstacles encountered in the cultivation of ginger is the rhizome rot disease which is mainly caused by Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. This study is aimed to know the growth ability and virulence level of the isolates on ginger rhizome and plants. The research was conducted in the laboratory and in the screen house by using Complete Random Design consisted of 10 treatments and 4 replications. The parameters observed were growth ability of F. oxysporum f.sp. zingiberi, rhizome rot disease symptoms, incubation period, extensive decay and weight difference of the rhizomes. The results showed that F. oxysporum f.sp. zingiberi which was stored for 4 years in sterile soil medium was still capable to cause damage to the rhizome and plants. Incubation periods of rhizome decay and plant symptoms were from 3 to 11.5 and 55.5 to 68.5 days, respectively. The most virulent isolate was MSO1 with extensive decay of rhizome and the wilting intensity were 108.95 mm2 dan 33.88%, respectively. IntisariJahe merupakan salah satu komoditas rempah dan obat yang banyak dibudidayakan di Indonesia. Salah satu kendala yang dihadapi dalam budidaya jahe adalah adanya gangguan penyakit busuk rimpang yang disebabkan (terutama) oleh Fusarium oxysporum Schlecht f.sp. zingiberi Trujillo. Penelitian bertujuan untuk menguji daya tumbuh dan virulensi isolat F. oxysporum f.sp. zingiberi pada rimpang dan tanaman jahe gajah. Penelitian dilakukan di laboratorium dan di rumah kasa menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang masing-masing terdiri dari 10 perlakuan dan 4 ulangan. Parameter yang diamati meliputi daya tumbuh F. oxysporum f.sp. zingiberi, gejala penyakit busuk rimpang, masa inkubasi, luas pembusukan dan selisih bobot basah rimpang. Hasil penelitian menunjukkan bahwa F. oxysporum f.sp. zingiberi yang telah di simpan 4 tahun dalam medium tanah steril mampu menyebabkan kerusakan pada rimpang dan tanaman jahe. Masa inkubasi gejala busuk pada rimpang serta gejala pada tanaman masing- masing berkisar antara 3–11,5 serta 55,5–68,5 hari.

Abstract

Mycoviruses are viruses that infect fungus. In plant pathogenic fungi, mycoviruses infection may cause hypovirulence. Therefore, mycoviruses could be developed as biological control agents against the plant pathogenic fungi. Abroad, mycoviruses have long been studied and developed into biological control agents. So far, many mycoviruses have been and are being developed as biological control agents. One that has been successfully manipulated is the Cryphonectria hypovirus 1 to control blight disease on chestnut trees (Castanea dentata). In Indonesia, in brief, mycoviruses has not been sufficiently investigated. This article is aimed to introduce mycoviruses in Indonesia, as well as to inform that a study on mycoviruses has been underway in the country IntisariMikovirus adalah virus yang menginfeksi jamur. Pada jamur patogen tumbuhan, infeksi mikovirus dapat menyebabkan hipovirulen. Dengan demikian mikovirus dapat dikembangkan sebagai agens pengendali hayati terhadap jamur patogen tumbuhan. Di luar negeri mikovirus sudah sejak lama dikaji, diantaranya adalah untuk dikembangkan sebagai agens pengendali hayati. Sampai sekarang sudah banyak mikovirus yang telah/sedang dikembangkan sebagai agens pengendali hayati. Salah satu yang sudah berhasil adalah Cryphonectria hypovirus 1 untuk mengendalikan penyakit hawar kastanye (Castanea dentata). Di tanah air, mikovirus dapat dibilang belum dikaji secara memadai. Artikel ini bertujuan untuk memperkenalkan mikovirus di tanah air, sekaligus menginformasikan rintisan kajian mikovirus yang telah dilakukan di tanah air.

Abstract

Red palm mite, Raoiella indica Hirst (Acari: Tenuipalpidae), has emerged as a new threat to coconut plantation in Indonesia. To control this mite, understanding on its biology is essential. The effects of three coconut varieties (Salak Dwarf, Local Sumenep Tall, and Hybrid coconuts) on the development and fecundity of R. indica were determined under laboratory conditions at 26−28oC, 80% RH, and photoperiod of 12:12 (L:D). The life cycle of R. indica consisted of the egg, larva, protonymph, deutonymph, and adult stages. Total development time of immature females was significantly influenced by coconut varieties. The shortest immature developmental time occurred at Salak Dwarf variety (26.07 days), whereas no significant difference of development time of immature female on Hybrid and Local Sumenep Tall varieties was found. Moreover, there was also no significant difference on the development time of immature male and on the fecundity of the mite among different coconut varieties. IntisariTungau merah kelapa, Raoiella indica Hirst (Acari: Tenuipalpidae), merupakan ancaman baru bagi perkebunan kelapa di Indonesia. Pemahaman mengenai biologi diperlukan untuk strategi pengendalian tungau tersebut di masa datang. Pengaruh tiga varietas kelapa yang berbeda (Genjah Salak, Lokal Sumenep, dan Hibrida) terhadap perkembangan dan keperidian R. indica diamati pada kondisi laboratorium dengan suhu 26−28oC, kelembapan nisbi 75−85%, serta pencahayaan 12 jam terang dan 12 jam gelap (L:D=12:12). Siklus hidup tungau terdiri dari telur, larva, protonimfa, deutonimfa, dan dewasa. Hasil pengujian menunjukkan bahwa waktu perkembangan betina pradewasa dipengaruhi secara nyata oleh varietas kelapa. Waktu perkembangan paling pendek terdapat pada kelapa Genjah Salak (26,07 hari), sedangkan waktu perkembangan betina pradewasa tidak berbeda nyata pada kelapa Hibrida dan Dalam Lokal Sumenep. Hasil lain pengujian menunjukkan tidak terdapat perbedaan nyata waktu perkembangan jantan pradewasa dan keperidian pada ketiga varietas.

Abstract

Vorstenlanden tobacco is the best product of PT Perkebunan Nusantara X (PTPN X) Klaten, Central Java that is commonly produced into high economic value cigars. During the planting season of 2010/2011, there was an epidemy of leaf curl disease that caused billion rupiahs financial loss. Several efforts had been done, including the use of pesticides, but the result had not been satisfactory. Therefore, this research aimed to identify the pathogen of tobacco leaf curl disease and conduct integrated control system using three combinations in the nursery [A (biological agents treatment, plastic screenhouse, without physical barrier); B (biological agents treatment, plastic screenhouse + screen plot, with physical barrier of single screen, and sprayed insecticide); C (biological agents treatment, plastic screenhouse + single screen plot, with physical barrier of double screens, and fogging using white oil + insecticide)] and planting area [A (physical barrier of single screen and sprayed insecticide); B (physical barrier of single screen, sprayed insecticide, and sanitation of broad leaf weed + eradication of infected plant); C (physical barrier of double screens, fogging white oil + insecticide, and sanitation of broad leaf weed + eradication of infected plant)]. The result showed that leaf curl disease that occured at PTPN X Klaten was caused by Begomovirus, based on PCR result using Krusty and Hommer primers for Begomovirus Coat Protein gene. The most effective integrated disease control of leaf curl disease in the nursery was C combination, that consisted of biological agents treatment on the seedlings medium, screenhouse covered by plastic and double screens that was combined with physical barrier of double screens around the field, and fogging using white oil+insecticide of pyrethroid active ingredient. The most effective integrated disease control of leaf curl disease in the field was the same C combination, that consisted of the use of physical barrier of double screens, environmental sanitation of weeds around the field and eradication of infected plants and fogging using white oil + insecticide of pyretroid active agent.   IntisariTembakau vorstenlanden merupakan produk andalan PT Perkebunan Nusantara X (PTPN X) Klaten, Jawa Tengah sebagai bahan baku cerutu yang bernilai ekonomi tinggi. Pada musim tanam 2010/2011 telah terjadi epidemi penyakit keriting atau kerupuk tembakau dengan kerugian mencapai milyaran rupiah. Upaya pengendalian yag telah dilakukan dengan mengandalkan pestisida tidak memberikan hasil yang memuaskan. Oleh karena itu, penelitian ini ditujukan untuk mengidentifikasi patogen penyebab penyakit kerupuk tembakau dan melakukan pengendalian secara terpadu dengan menggunakan tiga macam kombinasi yang dilakukan di pembibitan [A (perlakuan agens hayati, penyungkupan plastik, tanpa barier fisik ); B (perlakuan agens hayati, penyungkupan, barier fisik tunggal, dan penyemprotan insektisida); C (perlakuan agens hayati, penyungkupan, barier fisik ganda, dan aplikasi white oil)] dan di lahan pertanaman [A (barier fisik tunggal dan insekstisida); B (barier fisik tunggal, insektisida, dan sanitasi gulma); C (barier fisik ganda, white oil + insektisida, dan sanitasi gulma)]. Hasil penelitian menunjukkan bahwa penyakit kerupuk tembakau di PTPN X Klaten disebabkan oleh Begomovirus berdasarkan hasil PCR menggunakan primer Krusty dan Hommer untuk gen Coat Protein Begomovirus. Pengendalian terpadu penyakit kerupuk di pembibitan yang paling efektif adalah kombinasi C yang terdiri dari perlakuan agens hayati pada media bibit, penyungkupan rangkap plastik + waring ganda dipadukan dengan barier fisik berupa waring ganda sekeliling lahan dan aplikasi white oil + insektisida berbahan aktif piretroid dengan cara fogging. Demikian juga pengendalian terpadu penyakit kerupuk di lapangan yang paling efektif adalah kombinasi C yang terdiri dari perlakuan agens hayati pada media bibit, sanitasi gulma di sekitar lingkungan pertanaman dan eradikasi tanaman sakit, penyungkupan rangkap plastik + waring ganda dipadukan dengan barier fisik berupa waring ganda sekeliling lahan dan aplikasi white oil + insektisida berbahan aktif piretroid dengan cara fogging.
