Evaluation of Insecticides against Stemborers in Maize

In the field experiments conducted during Kharif 2012 and Rabi 2012-13 at Maize Research Centre, Rajendranagar to find out an alternative to endosulfan which was recommended against stem borer in maize, insecticides were sprayed at the recommended dosages at 12 DAG and observations were recorded at 45DAG and subjected to RBD analysis after angular transformation. Mean infestation was observed to be the lowest in the plot treated with chlorantriniliprole 18.5 SC (1.28%) followed by £cyhalothrin 5CS (2.33%). Mean per cent deadhearts was lowest i.e., 0.41 in the £-cyhalothrin treated plot followed by 0.61 in Indoxacarb treatment.
