Abstract
Two field experiments were conducted to study the impact of emamectin benzoate on
coccinellids of bhendi. Emamectin benzoate 5 SG and 1.9 EC @ 7,11 15 and 20 g a.i. ha -1 were
tested in comparison with Proclaim 5 SG @ 11 g a.i. ha -1 and endosulfan 35 EC @ 350 g a.i. ha -1
Observations on the population of coccinellids were made prior to spraying and on 3, 7, 10
and 14 days after spraying from 10 randomly tagged plants per plot and the mean worked out.
Results showed that emamectin benzoate 5 SG and 1.9 EC was found to be safer to coccinellids
at all concentrations tested. The highest population was recorded in plots treated with
Emamectin benzoate @ 7 g a.i. ha -1 followed by emamectin benzoate @ 11 g a.i. ha -1 ,
respectively.
