Three field experiments were conducted including several insecticides with different formulations, dosages and application methods to control the lesser cornstalk borer (Elasmopalpus lignosellus) on maize (Zea mays L.). In relation to the application methods, insecticides were applied in furrow at planting time as seed coating and as spray after plant emergence. Evaluations were based on the number of emerged plants (initial stand), number of surviving plants (final stand), number of attacked plants, and yield. The number of attacked plants was surveyed in alternated days. Insecticides applied as planting time gave good protection of the seed and/or seedlings against soil pests. Aldrin in seed coating and endrin in furrow were among the bes...
