Pathogenic fungi pose constraints and reduce shallot production. Trichoderma sp. is an antagonistic fungus capable of controlling pathogen growth in shallots. The aim of this study was to determine the characteristics of Trichoderma sp. and pathogens in shallots and to assess the antagonistic ability of Trichoderma sp. against shallot pathogens (Allium ascalonicum L.). Trichoderma sp. and shallot pathogens were isolated using a serial dilution agar plate method using potato dextrose agar medium with 7-day incubation. The antagonistic activity of Trichoderma sp. against shallot pathogens was evaluated based on the dual culture method. In this study, we successfully isolated Trichoderma harzianum from the shallot leaf and its root systems. Moreover, four morphologically distinctive pathogens from shallot roots and leaves were successfully isolated (l Aspergillus sp., Colletotrichum sp., Phytium sp. and Penicillium sp. T. harzianum was found to have the ability to inhibit 23.45% growth of Aspergillus sp, 26.19% growth of Colletotrichum sp., 75.40% growth of Phytium sp., and 40.38% growth of Penicillium sp. In conclusion, the isolated T. harzianum had a strong antagonistic activity against some pathogens in the shallot, but the activity was weak against some others.

Shallot (Allium ascalonicum L.) is a horticultural commodity that has high economic value and is needed every day by the community. Attack by pets and pathogens on shallot cultivation cause a decrease in crop productivity. The pathogen that often attacks shallot plants is Fusariumsp. and Alternaria sp. This study aims to obtain endophytic fungi from shallot leaves that can control Fusarium sp. and Alternaria sp. The endophytic fungus isolation method uses healthy shallot leek samples while the pathogen isolation uses unhealthy leaves. The antagonism potency test was conducted using the dual culture method with an incubation time of 7 days at 25-30oC. Based on the results of the study, there were 4 isolates of endophytic fungi on shallot leaves, namely EA1 isolates (Aspergillus niger), EA2 isolates, EA3 isolates (Clasdoporium sp.) and EA4 isolates (Phyllosticta sp.). The results of the antagonist test showed that the endophytic fungus EA1 was able to inhibit the fungus Fusarium sp. and Alternaria sp. maximally (strong) with an average value of Fusarium sp. of 62.72% while Alternaria sp. 67.83 %. The endophytic fungus EA2 was also able to inhibit both of these pathogens but it was moderately categorized with an average value of Fusarium sp. 52.11 % and Alternaria sp. 53.28%. The mechanisms of inhibition are competition and hyperparasitism.
