Abstract

Information about genetic variation of Ganoderma spp. As a couse of rot disease on plantation crops is necessary for consideration in efforts to protect crops. Exploration of the use of biological agents, especially Trichoderma spp., for the control of Ganoderma on forestry crops is still limited to laboratory testing. Its effectiveness to control Trichoderma spp. To protect plants in the nursery sengon being carried out, as well as to deternime its role in improving plant growth.

Abstract

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing tree species, and its wood is readily available because it has been widely cultivated in Indonesia. Efforts to propagate sengon plants are carried out through breeding activities in the nursery. The study aimed to identify the fungus that causes leaf disease on sengon plants and calculate the extent and intensity of attacks by the fungus that causes leaf disease on sengon in the Dramaga Bogor Permanent Nursery. This research consisted of pathogenicity test activities, including field observations, Koch's postulates, and the identification of fungal species. The study used a Completely Randomized Factorial Design. The disease symptoms found around 2 months of sengon leaves at the observation site were leaf fall, leaf spot, and leaf blight. The identified fungus that caused leaf fall was Rhizoctonia sp. The fungus that caused leaf spots was Colletotrichum sp., and the fungus that caused leaf blight was Fusarium sp. Fusarium sp. resulted in the highest percentage of attacks, with a disease incidence of 67% and a disease severity of 57%. Keywords: characteristics, identification, Koch`s postulates, morphology
