Abstract
One of the major reasons for the low productivity of maize is damage by insect pests, notably the stem borer, Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae). Investigations have been carried out to evaluate the efficacy of certain insecticides and neem-based formulations for the management of maize stem borer. Evaluation of the efficacy of 0.035% endosulfan for the management of maize stem borer at different stages of infestation has also been undertaken. The experiments were conducted in India during the monsoon season of 1993 and 1994. A single application of carbofuran 3G (at 7.5 kg/ha in leaf whorl) in a 15 day-old crop proved to be most effective in protecting against the borer, if the infestation occurs up to 6 days after application. Also, a single application of 0.035% endosulfan was highly effective in protecting the crop when applied 2 days after borer infestation and moderately effective when applied up to 6 days after borer infestation. Insecticidal spraying in later stages proved to be ineffective. Keywords: Stem BorerChilo PartellusManagementNeem-based FormulationsMaize Zea Mays
