UJI ANTAGONIS CENDAWAN ENDOFIT GULMA (AXONOPUS COMPRESSUS) DALAM MENEKAN FUSARIUM OXYSPORUM PADA TANAMAN CABAI MERAH SECARA IN VITRO
Red chili is one of plants that is widely cultivated by community, especially farmers both in the highlands and in the lowlands. One of the risks in chili cultivation is pathogen attack. The fusarium oxysporum wilt is one of the pathogens known to attack the chili plants. The control that can be done to prevent this disease is biological control by using endophytic fungi from the axonopus compressus weeds which thrive on the red chili plants attacked by the fusarium oxysporum pathogen. This research was conducted to find out the endophytic fungi from the axonopus compressus weeds which had the potential to supress the growth of fusarium oxysporum on red chili plants throught in vitro. this research was mainly conducted on the plant protection Laboratory of Borneo Tarakan University. The endophytic fungi were obtained by cleaning the surface of the leaves and roots using 1% of NaOCL and 70% of alcohol, then rinsed with sterile distilled water and cut to a size of 1 cm them implanted on PDA media (Potato Dextrose Agar). The fungi were identified macroscopically and microscopically, then tested for its pathogenicity and then continued with the antagonist ability test. The results of the research found that there were 34 isolates of fungi from the axonopus compressus weeds. There were only 2 out of 34 isolates which were non-pathogenic and able to suppress the growth of fusarium oxysporum wilt disease.
