Abstract

Brinjal shoot and fruit borer, Leucinodes orbonalis Guenee is a major pest. The frequent use of toxic chemical insecticides ultimately poses a problem due to pollution of the environment, health hazards, and adverse effects on beneficial organisms. Hence, the current researches looked into the efficacy of various botanicals against brinjal pests. This experiment was carried out to see how ethyl acetate and methanol extracts of grinded seeds of Ricinus communis, Abroma augusta, and Bombax ceiba affected the growth of brinjal shoots and fruit borers. Among the three plant extracts of ethyl acetate, 100% of R. communis and A. augusta extracts controlled 100% borers after 72 h of administration, 50 and 25% of R. communis extract controlled 100% borers after 72 and 96 h of administration. In the case of methanolic extracts, 100% of A. augusta extract controlled 100% borers after 72 h of administration, and 50 and 25% of R. communis extract controlled 100% borers after 72 and 84 h of treatment, respectively. When compared with the other two botanical extracts, R. communis seed extract performed the best against the pest attack. A. augusta and B. ceiba seed extract showed moderate efficacy against those pests.

Key words: Crude extract, brinjal pest, insecticides, botanicals, pest control, ethyl acetate, methanol extracts.
