Abstract

Mosaic disease on patchouli has developed very rapidly, in a period of 3 years it has spread to patchouli cultivation centers in Sumatra, Java, and Sulawesi. Therefore, prevention of the spread and control of this disease is a major concern. Volatile oil and plant extracts contain active substances that can inhibit viral infections in plant tissues. The highest percentage of mosaic virus inhibition originating from patchouli plant in Chenopodium amaranticolor test by nanoemulsion formula citronella dose 1% (74.87%) and clove dose 0.5% (43.55%). Citronella nano pesticide fragrant dose of 1% with the application time every month effectively suppresses the development of mosaic disease in patchouli plants of Sidikalang variety in Bandung-West Java and Banten. This study aims to look at the effectiveness of the clove nano biopesticide formula against patchouli mosaic virus and its economic feasibility study. The study was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. This study was compiled with Randomized Block Design (RBD) with 5 treatments of 10 replications and each replication of 100 plants. The results obtained showed that the efficacy of citronella, clove, and commercial citronella (Asimbo) nano biopesticide formulas on the intensity of mosaic disease compared to without treatment were 14.68%, 9.06%, and 5.83%, respectively. While the intensity of attack of patchouli leaf rollers were 38.03%, 35.21%, and 0% respectively. The efficacy of chemical insecticides on aphids attack was 32.39%, not different from the administration of the biopesticide nano formula citronella and clove. The yield loss of patchoulina 2 varieties compare with control without treatment ranged from 5.14 to 14.96%. Levels of patchouli alcohol> 30% (meet SNI standard of quality) but oil yield <1. Nano Biopesticides cloves have the potential as biopesticides to control plant viruses.
