Pokkahboeng is the important disease on sugarcane and can reduce sugar production. This research was study to determine the effect of UV to pathogenicity of F. moniliforme. This research has conducted at green house of Faculty of Agriculture Universitas Sumatera Utara from July-October 2016 using completely randomized design (CRD) non factorial and five treatments: M0, M1, M2, M3, M4 (without UV exposure, UV exposure for 15, 30, 45, and 60 minutes) with four replications. The results showed that pathogenicity of F. moniliforme was declined after UV radiation and UV irradiation for 45 minutes was the most efficient time to suppress the pathogenicity of F.moniliforme.
Penyakit pokahbung yang disebabkan oleh jamur Fusarium moniliforme adalah penyakit penting pada tanaman tebu yang bisa menurunkan produksi gula. Penelitian ini bertujuan untuk menguji pengaruh penyinaran ultra violet terhadap patogenitas F. moniliforme. Penelitian dilaksanakan di Rumah Kaca Fakultas Pertanian Universitas Sumatera Utara pada bulan Juli-Oktober 2016 menggunakan rancangan acak lengkap non faktorial dengan 5 perlakuan yaitu M0, M1, M2, M3, M4 (tanpa pemaparan UV, pemaparan UV selama 15, 30, 45, dan 60 menit) dan empat ulangan. Hasil menunjukkan bahwa patogenitas F. moniliforme menurun setelah dilakukan penyinaran UV dan lama penyinaran paling efektif untuk menurunkan patogenitas adalah 45 menit.
