abstract
The present investigation on field efficacy of some botanicals viz., Aloevera (Aloe vera), Nirgundi (Vitex negundo), Datura (Datura stramonium), Calotropis (Calotropis gigantean), Soapnut (Sapindus mukoros), Arusa (Adathoda vasiva) @ 5% aqueous extract and Pongamia soap (Pongamia pinnata) @ 1% against gram pod borer, Helicoverpa armigera on pigeonpea, were carried out during 2016(June)-2017(January), at College of Agriculture, JNKVV, Jabalpur. Result revealed that Nirgundi @ 5% (w/v) was most effective (3.06 larvae / 5 plants) and significantly superior to all other treatments followed by Calotropis @ 5% (w/v), Pongamia soap @ 1% (w/v), Arusa @ 5% (w/v) and Datura @ 5% (w/v), and population ranged between 3.47 to 3.78 larvae / 5 plants, and were at par with each other. The least effective treatment was Ghikavera @ 5% (w/v) (3.98 larvae / 5 plants), but significantly better than control (4.71 larvae/ 5 plants). Overall result revealed that nirgundi leaf extract has good potential to control H. armigera.
