ABSTRACT
Bacterial wilt disease on patchouli and its control strategy
Bacterial wilt disease is one of the most serious diseases on patchouli plant in West Sumatra, North Sumatra, and Nanggroe Aceh Darussalam (NAD). The disease is caused by Ralstonia solanacearum and reduces patchouli production as high as 6080%, so that it is a constraint in increasing patchouli productivity. The pathogen can be controlled by using tolerant varieties such as Sidikalang, cultural method (fertilizer application, organic matter, and mulch), biological control (Pseudomonas fluorescens and Bacillus spp.), botanical pesticide (lemon grass), chemical control (bactericide), and preventing pathogen spreading from infected area to non-infected area. Bacterial wilt disease should be controlled integratedly by combining various control techniques.
