Efficacy of emamectin benzoate in the management of vegtable pests

Field experiments were conducted to find out the bio-efficacy of emamaectin benzoate 5 SG against brinjal shoot and fruit borer, Leucinodes orbonalis, diamondback moth of cabbage, Plutella xylostella and the okra fruit borer, Earias vittella. Two sprays of each treatment were applied after initiation of infestation. On the basis of post treatment larval population and damage, emamectin benzoate was found to be most effective against all the test insects. In all the three test dosages of emamectin benzoate, no significant difference was noted in the level of infestation or damage caused by the three insects. Emamectin benzoate was effective against all the three insects even at the lowest dose i.e., 7.50 g a.i./ha against brinjal shoot and fruit borer and diamondback moth and at 5.00 g a.i./ha against okra fruit borer.
