Abstract

This study was conducted to isolate filoplan unicellular microbes which have antibiosis ability and characterize the secondary metabolite produced to inhibit Collectotrichum capsici in-vitro. This research was conducted at the Departement Plant Pest and Diseases, University of Brawijaya. Microbe isolated from the surface of chilies in a different age. Isolates microbes were tested for antagonistic potential against C. capsici. The persistence of the potential antagonist under different conditions of pH, temperature, and the light was also examined. An antagonist test was conducted to confirm the antibiosis mechanism. Furthermore, extracts were characterized using pH, light exposure, and temperature. The most potential antagonist was identified as isolate C3C with 36.20% inhibition. pH 5, 350C temperature, and light exposure of 0% is the best media optimization with the percentage of inhibition 37.5%, 38.2%, and 42.3%.

Abstract

Mango is a local fruit that is widely grown in Indonesia. Mango has several benefits for human life, including as a source of vitamins and industrial raw materials. This study aims to obtain pathogenic fungi that have the ability to cause disease in mango plants. This research was conducted in mango orchards in the provinces of South Sumatera, West Kalimantan, East Java, and Bali. Pathogenic fungi were observed from stems, leaves, and fruit. All symptoms of physiological and morphological deviations were observed to identify the cause. Then the identification procedure uses a supporting literature library. Pathogenic fungi were found, namely Xanthomonas citri pv. mangiferaeindicae, Ganoderma lucidum, Elsinoe mangiferae, Colletotrichum gloeosporioides, Ganoderma applantum, Paratetranychus yothersi, and Bemisia tabaci.

Abstract

Cocoa is an important commodity crop in Indonesia. However, current obstacles related to the problem of cocoa shell litter which is slow to decompose are an obstacle in plantation management. Therefore it is necessary to conduct research related to the exploration and identification of saprophytic fungi in cocoa pod litter. Samples of cocoa pod litter were taken at PTPN XII, while the isolation and identification processes were carried out at the Mycology Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. From the results of macroscopic and microscopic identification, nine isolates of saprophytic fungi were obtained consisting of seven genera, namely Candida sp., Penicillium sp., Fusidium sp., Rhizopus sp., Chepalosporium sp., Trichoderma sp.1, Trichoderma sp.2, Aspergillus sp., and Trichoderma sp. 3.
