In the cultivation of patchouli, several constraints are faced, such as bacterial wilt disease by Ralstonia solanacearum, budog disease by fungus Synchytrium pogostemonis, and viral infection caused by Potyvirus, Potexvirus, Fabavirus, and Cucumovirus that has spread in much central cultivation of patchouli, in Indonesia. Attempts to control the viral disease have been done. However, there is no information in terms of inhibiting viral infection and control of viral vectors in patchouli plants in the nursery as well as in the field. The technique has been established to eliminate the virus from infected patchouli plant tissue by apical meristem culture and has also been obtained in the early detection techniques of viruses that infect patchouli plants. In addition, to control the disease on the patchouli, further study needs to reduce and eliminate the effect of residues of compounds that can inhibit growth and production, especially in some plantation crops. The research was conducted in 2014, with subjects studied as follows (1) study the effect of some biopesticides on the development of the viruses and (2) study the effect of some biopesticides against viral vectors. The materials used were of Chenopodium amaranticolor plant, patchouli as mosaic virus inoculum, neem, citronella, and clove oil, and emulsifier (Tween 80). The results showed that clove oil and in a mixture with citronella oil at a concentration of 1% could suppress the growth of viral 45 and 32% respectively. Biopesticides, such as neem oil and in a mixture with clove oil, and citronella oil were able to inhibit the development of Potyvirus that are transmitted by Aphis gossypii.
