Evaluation of Kemiri Sunan (Reutealis trisperma Blanco) Seed Oil Nanoemulsion as insecticide against Planococcus minor (Hemiptera: Pseudococcidae)

Abstract

Estate commodities and flowering plants are mostly attacked by Planoccocus minor. Nowadays, botanical pesticide nanoemulsion technology is developing to be used to control insect pests. To evaluate the kemiri sunan seed oil nanoemulsion as insecticide against P.minor was the objective of this study. Completely Randomized Design (CRD) with four replication was used on the kemiri sunan evaluation test. Each replication consist of seven concentration (0,2%; 0,39%; 0,78%; 1,56%; 3,13%; 6%; and water as control). Analysis of variance (ANOVA) at α 95% followed by Duncan multiple test at α 5% was carried out. The evaluation result showed an increase in the insecticidal effect of kemiri sunan seed oil nanoemulsion against the insect species when formulated as a nano-emulsion. The application of kemiri sunan seed oil nanoemulsion for five day after treatment was able to cause the mortality of P. minor as much as 90%. Within 5 days after treatment, LC50 was 0.09 % and LT50 was 3,7 days. It is implies that the kemiri sunan seed oil nanoemulsion when to be sprayed may kill directly to the target pest and it is needed around 3,7 days to kill 50% population of pest. The results obtained indicate that kemiri sunan seed oil based nanoemulsion formulations can be used as toxicants for the control of P. minor. The kemiri sunan seed oil based nanoemulsion can be developed into botanical pesticides. Low chemical residues, safe for natural enemies and can be used as component in integrated pest management are the advantages of The kemiri sunan seed oil based nanoemulsion.
