BIOEFFICACY STUDY OF BIORATIONAL INSECTICIDE ON BRINJAL
ABSTRACT In the present study, bioefficacy of spinosad (56.25, 72 and 90 g a.i. ha-1) and emamectin benzoate (5, 6.25 and 12.5 g a.i.ha-1) was studied in comparison to cypermethrin (50 g a.i. ha-1) and selfformulated neem seed extract (5 %). Field experiments were undertaken for two cropping seasons...

| Summary: | ABSTRACT In the present study, bioefficacy of spinosad (56.25, 72 and 90 g a.i. ha-1) and emamectin benzoate (5, 6.25 and 12.5 g a.i.ha-1) was studied in comparison to cypermethrin (50 g a.i. ha-1) and selfformulated neem seed extract (5 %). Field experiments were undertaken for two cropping seasons during kharif 2005 and summer 2006. From the study it was found that spinosad afforded moderate control of jassid, whitefly and aphid. However, it was found to be the most effective against BSFB. Although corresponding yield recorded in cypermethrin (check treatment) was higher (16.30 and 21.01 t ha-1) it was not significantly different than that noticed in spinosad and emamectin benzoate. |
