Fusarium oxysforum f. sp. cubense (Foc) is one of the important pathogens causing fusarium wilt on banana plants. This pathogen reduces the productivity of banana plants and cause more than 35 % of dead banana plant. The disease management has been done from chemical control to biological control. The use of Non Phatogenic Fusarium (FoNP) in some plants is quite effective in suppressing fusarium wilt disease. The aim of this research was to know the potency of FoNP isolates E3 and E5 (BALITTRO, Bogor) which were applied on barangan cultivar ‘barangan’ to control fusarium wilt disease. The method of this research was Randomized Complete Design Factorial withtwo isolates of-FoNP; i.e. E5 and E3. Application was conducted by immersing the banana seeds with the fungal incolum. Conidia suspension (106 conidia/ ml) and FoNP methabolites were used, with or without pathogen with the following treatments: P1 : conidia suspension E5 with Foc; P2 : conidia suspension E3 with Foc; P3 : conidia suspension E5 without Foc; P4 : conidia suspension E3 without Foc; P5 : metabolite E5 with Foc; P6 : metabolite E3 with Foc; P7 : metabolite E5 without Foc; P8: metabolite E3 with Foc; P9 : Foc; P10 : without Foc. The results showed that there weas no symptoms caused by Foc on leaves or banana herbs in the field. In the in vitro experiments, Non Pathogenic Fusarium isolates E5 and E3 could inhibit the growth of Foc with the inhibiting zone was 29. 16 % and 19. 22 % respectively. Keywords: Barangan Cultivar, Fusarium oxysforum f. sp. cubense, non pathogenic fusarium, fusarium wilt disease.

The beneficial microorganisms in the rhizosphere are very abundant. This potential, especially antagonistic fungi can be used to control soil-borne pathogens, including in controlling white root rot disease which is a soil-borne pathogen. This study aims to determine the antagonistic fungal diversity of healthy rubber rhizosphare and infected with white root rot disease. This research was conducted in Plant Disease Laboratory, Faculty of Agriculture, Universitas Sumatera Utara from October 2017 until March 2018. The research was conducted by collecting of soil samples from healthy rubber plant and infected white root rot disease in rubber plantation of Silomlom Village, Simpang Empat Sub-district, of Asahan Regency then soil samples were isolated in the Laboratory until obtained a pure fungi isolates and antagonistic test and identified to the genus level. The results showed that fungi obtained in healthy plant rhizosphere were Mortierella, Humicola, Fusarium, Aspergillus, Gliocladium, Penicillium, Trichoderma and on the plant rhizosphare attacted white root disease obtained fungi Trichoderma, Humicola, and Phialophora. The results of antagonistic test showed that the highest inhibition was Mortierella that was 90%, then Trichoderma was 71.85%, Aspergillus 66.46% and the lowest was Humicola 27.78%.

Serangan hama merupakan salah satu faktor yang mempengaruhi produktivitas bawang merah. Studi keanekaragaman serangga merupakan langkah awal dalam penanggulangan hama pada tanaman. Tujuan dari penelitian ini adalah untuk membandingkan keanekaragaman serangga pada tanaman bawang merah pada lahan dengan penanaman menggunakan sistem konvensional semi organik di Kabupaten Simalungun. Penelitian dilaksanakan di Desa Karang Sari dan Desa Karang Rejo, Kecamatan Gunung Maligas, Kabupaten Simalungun dan kegiatan identifikasi serangga dilaksanakan di Laboratorium Hama Tumbuhan, Fakultas Pertanian Universitas Sumatera Utara. Penelitian menggunakan metode survei, dilakukan pada lahan seluas 500. Pengamatan dilakukan sebanyak 7 kali, 1 kali pada saat persemaian, 1 kali sebelum transplanting ke lapangan, 3 kali pada masa vegetatif, dan 2 kali pada masa generatif. Pengambilan sampel dilakukan dengan menggunakan jaring serangga, perangkap kuning dan perangkap jatuh. Hasil penelitian menunjukkan bahwa terdapat 9 ordo serangga yang terdiri dari 18 famili di lahan semi organik, sedangkan di lahan konvensional terdapat 10 ordo yang terdiri dari 16 famili. Indeks keanekaragaman pada pertanaman secara semi organik sebesar 2,277 dan konvensional sebesar 2,332 menunjukkan keanekaragaman sedang. Indeks Kemerataan pada pertanaman secara semi organik sebesar 0,595 dan konvensional sebesar 0,581 menunjukkan kemerataan di kedua tempat termasuk tinggi. Tidak ada spesies serangga yang mendominasi di kedua tempat menunjukkan keanekaragaman yang tinggi.
