| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui 1) jenis jamur patogen penyebab penyakit pada gulma daun sempit pada perkebunan tebu, 2) informasi virulensi jamur patogen terhadap gulma daun sempit pada perkebunan tebu, dan 3) informasi virulensi jamur patogen gulma daun sempit terhadap tanaman budidaya. Penelitian dilaksanakan di Laboratorium Perlindungan Tanaman dan rumah kaca, Fakultas Pertanian, Universitas Jenderal Soedirman, Purwokerto dilaksanakan dari Oktober 2019 sampai Agustus 2020. Penelitian ini terdiri atas tiga tahap yaitu eksplorasi, identifikasi, dan uji virulensi jamur patogen gulma. Eksplorasi dilakukan dengan pengambilan sampel gulma bergejala menggunakan metode purposive random sampling. Uji virulensi dilakukan pada gulma dan tanaman budidaya, yaitu Imperata cylindrica, Cyperus kyllingia, Cyeperus rotundus, Eleusine indica, Digitaria ciliaris, Oryza sativa, Zea mays, dan Sacharum officinarum. Variabel yang diamati adalah intensitas penyakit, masa inkubasi, area under diseases progress curve (AUDPC), bobot tanaman basah, dan bobot tanaman kering. Hasil dari eksplorasi diperoleh jamur patogen Curvularia lunata dan Fusarium oxysporum. Perlakuan jamur C. lunata pada gulma C. rotundus menunjukkan intensitas paling besar di antara gulma yang lain, dan perlakuan F. oxysporum dengan intensitas 24,3% bahkan mampu menimbulkan kematian pada gulma C. rotundus. Sementara perlakuan jamur F. oxysporum menunjukkan intensitas yang lebih besar pada gulma D. ciliaris dengan kisaran 7,73%. Jamur patogen gulma daun sempit virulen terhadap gulma daun sempit dan tidak virulen terhadap tanaman budidaya yang diujikan. |

| Abtrak (Bhs. Inggris) | This study aims to find out 1) types of disease-causing pathogenic fungi in narrow leaf weeds on sugar cane plantations, 2) information on the virulence of pathogenic fungi against narrow leaf weeds on sugar cane plantations, and 3) information on the virulence of narrow leaf weed fungi against cultivated plants. The research was conducted in the Laboratory of plant protection and greenhouse, Faculty of Agriculture, Universitas Jenderal Sudirman, Purwokerto was conducted from October 2019 to August 2020. The study consisted of three stages: exploration, identification, and virulent test of the pathogenic fungi. Exploration used purposive random sampling method to symptomatic weeds. Virulent test was carried out on narrow leaf weeds and cultivated crops such as Imperata cylindrica, Cyperus kyllingia, Cyeperus rotundus, Eleusine indica, Digitaria ciliaris, Oryza sativa, Zea mays, and Sacharum officinarum. Variables observed are disease intensity, incubation period, area under diseases progress curve (AUDPC), wet plant weight, and dry plant weight. Results from exploration obtained pathogenic fungi Curvularia lunata and Fusarium oxysporum. The treatment of C. lunata in C. rotundus weeds showed the most intensity among other weeds, and the treatment of F. oxysporum with an intensity of 24,3 % was even capable of causing death in the weeds of C. rotundus. While the treatment of fungus F. oxysporum showed higher intensity in weeds D. ciliaris with a range of 7,73%. Pathogenic fungi weeds narrow leaves virulent against narrow leaf weeds and are not virulent against the cultivation plants tested. |
