Integrated Approaches for Managing Bacterial Wilt Disease (Enterobacter sp.) in Aceh Patchouli Plants

<p>Aceh Patchouli (<em>Pogostemon cablin</em> Benth.) is a significant export commodity for essential oil production in Indonesia. The wilt disease “matee tumbon” caused by <em>Enterobacter</em> bacteria is one of the obstacles to Aceh patchouli cultivation. This study aims to identify the most effective combination technique to control it. The study combined 25 treatment combinations in patchouli nurseries, and the five best treatment combinations were subsequently tested on patchouli plants in the field. The results showed that the five best combinations in controlling bacterial wilt disease in the nursery were 20% streptomycin sulfate + <em>Trichoderma</em> sp., 20% streptomycin sulfate + <em>Bacillus thuringiensis</em>, <em>Trichoderma</em> sp. + <em>B. thuringiensis</em>, 20% <em>streptomycin sulfate</em> + neem extract + <em>B. thuringiensis</em>, and neem extract + <em>Trichoderma </em>sp. + <em>B. thuringiensis</em>. Field results showed that the combination of neem extract, <em>Trichoderma</em> sp., and <em>B. thuringiensis</em> was effective in controlling the pathogen <em>Enterobacter</em> sp., causing bacterial wilt disease in Aceh patchouli plants. This combination of control techniques is an integrated approach to controlling bacterial wilt disease (<em>Enterobacter</em> sp.) in Aceh patchouli plants.</p>
