Penelitian bertujuan untuk mengetahui jenis jamur patogen pada gulma berdaun sempit, mengetahui viruensi jamur patogen terhadap gulma bedaun sempit dan mengetahui virulensi jamur patogen gulma terhadap tanaman budidaya padi dan jagung. Penelitian ini dilaksanakan di Laboratorium perlindungan tanaman dan screen house Fakultas Pertanian Universitas Jendral Soedirman pada bulan November 2016- April 2017. Penelitian dilakukan dengan tiga tahapan yaitu (1) Eksplorasi jamur patogen gulma berdaun sempit; (2) uji virulensi jamur patogen gulma berdaun sempit terhadap lima jenis gulma, dan (3) uji virulensi jamur patogen gulma berdaun sempit terhadap dua tanaman budidaya. Rancangan yang digunakan untuk uji virulensi adalah rancangan petak terbagi (split plot). Petak utama terdiri atas jamur patogen dan anak petak terdiri dari lima jenis gulma maupun dua jenis tanaman budidaya. Variabel yang diamati yaitu gejala penyakit, karakteristik morfologi jamur patogen, masa inkubasi dan intensitas penyakit. Hasil penelitian menunjukkan bahwa eksplorasi jamur patogen gulma berdaun sempit pada gulma Cyperus rotundus, Paspalum commersoni Lamk, Cynodon dactylon, dan Cyperus brevitolius didapatkan 3 jamur patogen yaitu Curvularia lunata, Fusarium solani, dan Choanephora cucurbitarum. Jamur F. solani merupakan jamur patogen gulma berdaun sempit yang paling virulen. F. solani mampu menimbulkan penyakit pada semua gulma yang diujikan. F. solani mampu menginfeksi gulma C. brevitolius dengan intensitas penyakit 20,24 % dan masa inkubasi 4,67 hari setelah inokulasi (hsi). Namun, jamur F. solani juga mampu menginfeksi tanaman jagung dan padi. Intensias serangan F. solani pada jagung sebesar 3,021%, sedangkan pada padi sebesar 1,10% dengan masa inkubasi 14-18 hari setelah inokulasi (hsi).

The research aimed to find the type of fungal pathogens in the narrow leaved weeds, the virulence of the pathogen against narrow leaved weeds, and the virulence of the pathogen to cultivated plant such as rice and corn. 
This research was conducted in the Laboratory of Plant Protection and screen house of Faculty of Agriculture, Jenderal Soedirman University from November 2016-April 2017. The research was done with three stages, those are, (1) the exploration of narrow leaved weeds pathogen fungal; (2) The virulence test of the pathogen against five different types of weeds, and (3) the virulence test of the pathogen fungus against two cutivated plants. The design used for virulence test was split plot design. The main plot consisted of pathogens fungus and the subplot consisted of five types of weeds as well as the two types of cultivated plants. Observed variables were symptom of disease, characteristic of fungal pathogen morphology, incubation period, and disease intensity.
Result of the research showed that the exploration of narrow leaved weeds pathogenic fungus in Cyperus rotundus, Paspalum commersoni, Cynodon dactylon, and Cyperus brevitolius obtained three fungal pathogens, i.e., Curvularia lunata, Fusarium solani, and Choanephora cucurbitarum. F. solani was the most virulent narrow leaved weeds phatogenic fungus. F. solani was able to cause disease in all tested weeds. F. solani was able to infect Cyperus brevitolius weeds with disease intensity as 20,24% and incubation period as 4,67 days after inoculation. However, F. solani was also able to infect corn and rice crops. The disease intensity on corn crops was 3,021% whereas on the rice crops was 1,10% with the incubation period as 14-18 days after inoculation.
