Sugarcane is an essential industrial that produce sugar in the world. Scirpophaga excerptalis attacks can reduce the productivity of sugarcane up to 34%. To enhance the resistance to multiple stresses, Silicon is one of the elements for its role. This research aimed to determine the effect of the provision of silica fertilizer as part of the Integrated Pest Management strategy. This research was conducted in the Plant Protection Department, Indonesian Sugar Research Institute. The compost given as treatment in this research was straw, cane, and corn composts. Organic silica fertilizer (compost) provides the same effect as inorganic silica fertilizer in increasing the induction of sugarcane resistance to sugarcane top borer (S. excerptalis). Rice straw compost was a compost fertilizer that provides the best sugarcane resistance to sugarcane top borer compared to sugarcane plants that treated with sugarcane and corn leave to compost

Lecanicillium lecanii is an insect pathogenic fungus that is often used for pest control and has a wide range of hosts. The L. lecanii is capable of infecting several types of host insects including the Order Orthoptera, Hemiptera, Lepidoptera, Thysanoptera and Coleoptera. The extent of this fungus host range was feared to have a negative effect on predator insects Menochilus sexmaculatus. This study aims were to determined the pathogenicity of the fungus L. lecanii against the imago predatory beetle M. sexmaculatus, to know how the predation ability and the number of eggs fecundity of Imago M. sexmaculatus after application L. lecanii. The research was arranged in Randomized Block Design with 4 replications. The conidia density of L. lecanii used were 106, 107, 108, 109 conidia/ml, 1 ml / l of lufenuron insecticide as positive control and sterile distilled water as negative control. The research showed that the mortality percentage of M. sexmaculatus due to L. lecanii application is low and medium. The L. lecanii was not affected for preying ability on imago M. sexmaculatus but gave effect to the number of eggs fecundity of imago M. sexmaculatus.

Bawang merah merupakan tanaman yang memiliki resiko tinggi dalam aktivitas budidaya pertanian, salah satunya adalah serangan OPT. Oleh sebab itu penggunaan pestisida menjadi tinggi. Tujuan penelitian ini adalah untuk mengetahui tingkat residu pestisida berbahan aktif Abamectin dan Mancozeb pada tanaman bawang merah di Kabupaten Probolinggo. Penelitian dilakukan di lahan pertanian bawang merah meliputi Desa Mranggon Lawang, Desa Sumberbulu, dan Desa Sumberkerang. Analisa residu dilakukan di Laboratorium Penyakit Tumbuhan, Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya. Waktu pelaksanaan pada bulan Mei sampai bulan Oktober 2021. Analisis residu pestisida dikerjakan menggunakan Gas Chromatography (Model 8000 TOP yang dilengkapi dengan Electron Capture Detector). Hasil penelitian menunjukkan semua sampel bawang merah meninggalkan residu pestisida. Namun residu pestisida masih berada di bawah ambang batas maksimal berdasarkan Standar Nasional Indonesia. Desa Mranggon Lawang yang menjadi desa sentra bawang merah terbesar di Kabupaten Probolinggo memiliki tingkat residu tertinggi dibandingkan dengan 2 desa lainnya. Hasil uji bahan aktif Abamectin pada daun sebesar 0,002; umbi 0,004; dan tanah 0,004 mg/kg. Sedangkan pada bahan aktif mancozeb pada daun 0,132; umbi 0,093; dan tanah 0,155 mg/kg. Hal tersebut menunjukkan bahwa perilaku petani bawang merah di Kabupaten Probolinggo terhadap penggunaan pestisida masih termasuk dalam batas wajar.

Phytophthora nicotianae merupakan patogen yang mampu memusnahkan tanaman tembakau pada tahap awal sehingga menyebabkan penyakit lanas dan menyebabkan kematian tanaman hampir 100%. Serangan dimulai dari dalam jaringan akar dan berlanjut hingga menghancurkan pembuluh pengangkut sehingga menyebabkan bibit tembakau layu. Kebijakan pengendalian penyakit harus menerapkan konsep pengendalian hama dan penyakit terpadu (PHT) secara bijaksana dan selaras dengan strategi PHT. Efektivitas bahan aktif fungisida dalam mengendalikan P. nicotianae harus diuji melalui uji khasiat yang meliputi pengujian dosis. Oleh karena itu, perlu dilakukan uji efikasi fungisida Trivia 73 WP (fluopikolid 6% dan propineb 67%). Pengujian dilakukan di Desa Sumberpucung Kabupaten Malang dengan menggunakan metode RAK (Rancangan Acak Lengkap) dengan 5 perlakuan dan 5 ulangan. Hasil penelitian menunjukkan bahwa fungisida Trivia 73 WP yang mengandung bahan aktif fluopikolid (6%) dan propineb (67%) dengan dosis 3 gram per liter efektif menurunkan angka kematian tanaman tembakau akibat patogen P. nicotianae.

Dermaga merupakan lokasi strategis untuk aktivitas bongkar muat barang, yang juga berpotensi menjadi habitat tikus, terutama spesies Rattus norvegicus. Tikus ini dapat berkembang biak dengan cepat di lingkungan yang kaya sumber makanan, seperti sisa bahan pangan yang tercecer di dermaga. Penelitian ini bertujuan untuk mengidentifikasi jenis tikus yang terdapat di kawasan dermaga dan mengevaluasi efektivitas berbagai jenis perangkap serta umpan dalam mengendalikan populasi mereka. Penelitian menggunakan dua jenis perangkap, yaitu bubu besi dan bubu bambu, dengan lima variasi umpan: (A) umpan racun antikoagulan komersial; (B) campuran beras, monosodium glutamat (MSG), minyak sawit, asam benzoat, ikan asin, dan parafin padat; (C) campuran beras, MSG, minyak sawit, asam benzoat, tepung kulit udang, dan parafin padat; (D) campuran beras, MSG, minyak sawit, asam benzoat, kelapa bakar, dan parafin padat; serta (E) campuran beras, MSG, minyak sawit, asam benzoat, dan parafin padat (sebagai kontrol). Hasil penelitian mengidentifikasi dua spesies tikus, yaitu R. norvegicus dan Bandicota indica, dengan populasi R. norvegicus hampir dua kali lipat dibandingkan B. indica. Dari lima jenis umpan yang diuji, campuran dengan tepung kulit udang terbukti paling efektif dalam menarik tikus, sedangkan umpan kelapa bakar dan kontrol tidak menghasilkan tangkapan. Perangkap bubu besi juga ditemukan lebih efektif dalam menangkap tikus dibandingkan bubu bambu. Keberhasilan umpan tepung kulit udang dipengaruhi oleh kombinasi aroma yang kuat, rasa yang menarik, dan kemudahan penggunaan. Penelitian ini memberikan wawasan penting mengenai metode pengendalian populasi tikus yang efektif di kawasan dermaga, melalui pemanfaatan preferensi alami tikus terhadap jenis umpan tertentu dan penggunaan perangkap yang sesuai.

The beet armyworm, Spodoptera exigua is a notorious pest that inflicts significant damage to shallot crops, especially leeks, causing leaves to wither due to brown spots and transparency. This issue often leads to excessive chemical control measures, which, in turn, promote insecticide resistance. This study hypothesized that symbiotic bacteria within S.exigua have the capacity to degrade chlorpyrifos-based insecticides. S.exigua samples were collected in Dringu, Gending, and Leces districts, Probolinggo, and subsequently examined for symbiotic bacteria with biodegradation potential. Bacterial exploration and identification were conducted from April to October 2023 at the Pesticide Toxicology Laboratory, Brawijaya University. The study analyzed the clear zone diameter produced by bacteria in media contaminated with chlorpyrifos-based insecticides as an indicator of biodegradation. Out of 41 surviving bacterial isolates, 10 demonstrated notable biodegradation capabilities. The Genus identification revealed that Erwinia sp., Pantoea sp., and Coryneform sp. were among the contributing bacteria. This research emphasizes the potential role of S.exigua-associated symbiotic bacteria in managing chlorpyrifos-resistant pest populations, offering a promising avenue for sustainable pest control methods.
