Abstract:
Brown rice is one of the local rice germplasm that is being developed in wetlands of South
Kalimantan. One of the production constraints is Fusarium disease with symptoms of yellowing,
drying and the plant will die. Biological control is a disease control solution to replace chemical
fungicides which is not only economical but also environmentally friendly. This study aims to
determine the effect of the application time of Trichokompos enriched Kelakai (Stenochlaena
palustris) solution on fusarium disease in brown rice. The study was conducted in a greenhouse using
the Completely Randomized Design method which consisted of four treatments, namely only
inoculated with the pathogen, and three times of application of Trichoderma which was added with a
solution of Kelakai namely one week before planting, at planting and one week after planting.. The
Fusarium pathogen was isolated from the sacred brown rice plant. In the process of composting goat
manure, Trichoderma sp. in rice media was added to produce Trikocompost. The results showed that
the application of Trichokompos enriched with Kelakai solution was effective in controlling Fusarium
disease in brown rice, both before planting, at planting and after planting. The effectiveness of the
control began to decrease in the second week after application, the effectiveness value from 90.48%
decreased to only 17.95% in the fourth week. Application of Trichokompos enriched Kelakai solution
with various application times can extend the incubation period of the pathogen 16,20 days after
inoculation compared to control 9,80 days after inoculation
