Abstract

Effect of Ultraviolet Irradiation on the Pathogenicity of Fusarium moniliforme Pokkahboeng Disease on Sugar Cane. 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) nonfactorial 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.   Key words : Fusarium moniliforme, sugarcane, ultraviolet

Abstract

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.
