Field Evaluation of Emamectin Benzoate 5 WG Against Coccinellid Predators in Cabbage Eco-System

Two field experiments on cabbage (Cv: Equatoria) were conducted, at Ammapatti (I season: August 2012 to November 2012) and Kuppampatti (II season: November 2012 to February 2013) of Tamil Nadu to evaluate the safety of new formulation Emamectin benzoate 5 WG at different doses (125, 150, 175 and 188 g/ha) against the standard check, Emamectin benzoate 5 SG (150 and 200 g/ha), Novaluron 10% EC (750 ml/ha) and Chlorantraniliprole 18.5% SC at 50 ml/ha for their safety to coccinellid predators in cabbage eco-system. Observation on the population of coccinellid was recorded prior to spraying and at 3, 7 and 10 days after each spraying from ten randomly selected plants in each replication and untreated check. The results showed that Emamectin benzoate 5 WG was found to be safer to coccinellid at all concentrations tested. The highest population recorded in plots treated with Emamectin benzoate 5 WG at 125 g/ha followed by Emamectin benzoate 5 WG at 150 g/ha, respectively.
