The aim of the present study was to test the efficiency of imidacloprid and thiametoxam via both, the maintenance of plant spacing and obtained grain yield and also to check the response of certain hybrids to the seed treatment with systemic insecticides. Eight commercial ZP hybrids, four medium early maturity and four full season hybrids, were selected to test imidacloprid and thiametoxam. Seeds of all hybrids, including the control, were treated with the fungicide Maxim XL 035-FS. Strip trials were performed in six locations in south Banat during the period of 2004-2007. According to the average values of obtained plant spacing and grain yields for both insecticides, it can be concluded that a positive response of maize to the seed treatments (364 to 570 kg/ha) was established under the conditions of a low abundance of soil pests, particularly Western corn root worm, during the 2004-2007 period. Although all eight hybrids expressed tolerance to both observed insecticides, it should be stated that the inconsistence of results can create a different impression.
