NANOEMULATION OF MIXED Tephrosia vogelii AND Piper aduncum AS AN ALTERNATIVE CONTROL OF CABBAGE PEST Crocidolomia pavonana

Abstract

Nanoemulsion is a preparation consisting of an oil phase and a water phase with particle sizes in the range of 20-200 nm. The study aimed to obtain a mixed nanoemulsion from Piper aduncum fruit and Tephrosia vogelii leaves as an active botanical insecticide against larvae of Crocidolomia pavonana. Nanoemulsions were made using a low energy method, namely spontaneous emulsification using a magnetic stirrer and then followed by a toxicity test. The nanoemulsion toxicity test was carried out singly and in a mixture on C. pavonana larvae using the deep leaf method. The results showed that at the LC50 and LC95 nanoemulsion of mixture T. vogelii and P. aduncum extract was synergistic and showed higher activity than a single nanoemulsion of T. vogelii and P. aduncum.
