Abstract


A field experiment on evaluation of botanicals for their bioefficacy against insect pests infesting brinjal was conducted at Agronomy Farm of B. A. College of Agriculture, Anand Agricultural University, Anand (Gujarat) during Summer 2012. Results concluded that among the seven botanical products evaluated, the spray of neem seed kernel extract (NSKE) @ 5% and neem oil @ 0.3% were found effective against sucking pests (aphid, leaf hopper and whitefly) as well as shoot and fruit borer infesting brinjal. Maximum fruit yield (5471 kg/ha) was harvested in the treatment of NSKE followed by neem oil (4228 (kg/ha). Maximum net realization (` 20450/ha) with highest (1:24.06) Incremental Cost Benefit Ratio (ICBR) were registered in NSKE. With respect to net realization, the treatment of neem oil ranked next to NSKE, but failed to show higher ICBR.
