Abstract

This study aims to evaluate the efficiency of basalt with two botanical aqueous extracts of Citrus aurantium and Nerium oleander (50g/L) against Aphis punicae and Planococcus citri in an organic pomegranate orchard. Basalt was applied as a foliar spray with two doses (1.5% and 3%), in the ground as a fertiliser (1.5%), and as a combined application (1.5%). Phenolic compounds of both plants were identified by HPLC-PDA/ESI-MS analysis. Seven and six flavonoids were detected in C. aurantium and N. oleander extracts, respectively. Hesperidin was more abundant in C. aurantium extracts; however, N. oleander extracts contained more quercetin rutinoside. A. punicae populations were significantly higher in control trees compared to the treated ones. A. punicae mortality rates reached high values above 90% for basalt and plants extracts and efficacy rates exceeded 80%. P. citri mortality rates reached 88% and 77%, and efficacy rates exceeded 75% and 66% for basalt and plant extracts, respectively. These findings may help to plan Integrated pest management strategies in organic orchards to avoid toxic chemical pesticides.
