Abstract

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

Abstract

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.

Abstract

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.
