Abstract

Organic fertilizer amendments reduce disease severity of Phytophthora palmivora root rot of duku (Lansium domesticum) seedlings. Phytophthora palmivora, is a deadly pathogen of duku, causing serious problem in the main production areas, especially in Jambi Province, Indonesia. The pathogen can infect duku plant in all stage of growth including seedlings. Organic fertilizer amended media might become a potential alternative option for this disease management. These studies were performed in soil media containing organic fertilizer of 0%, 10%, 20%, 30% (v/v), served as treatment, and subjected to completely randomized design with 5 replications. This research found that incorporating 20% of organic fertilizer into media was able to lower disease severity by 23%. The ability of organic fertilizer to increase media bacterial and maintain fungal density and increase chemicals of C-org, P, K, Ca, Mg and Zn played important roles in reducing disease development.
