Bio Efficiency of Medicinal Plant Extracts Against Rice Pest, Leptocorisa Oratorius as an Alternative to Chemical Pesticides.

Abstract

Conventional chemical pesticides cause a lot of biotic and abiotic hazardous effects, and the need for an eco-friendly alternative is vital. Bioactive compounds from plant extracts are promising candidates to be established as potential insecticides. The current study investigates the insecticidal potential of five aqueous plant extracts, including Cassia fistula, Annona muricata, Atrocarpus heterophyllus, Coleus aromaticus and Clerodendron infatunatem against L.oratorius. Qualitative analysis of the aqueous plant extracts was also examined for its phytochemical constituents. Maximum mortality was caused by C. fistula (77.34%) at 15% and minimum mortality was observed in C. infatunatem (17.33%) at 3% concentration. Various phytochemicals of high bioactivity like phenols, tannins, flavonoids, saponins, terpenoids, alkaloids, quinones and fatty acids present in the plants under study have the potential to act as insecticides against the rice pest L.oratorius.
