From 1993-1995, chemical and biological insecticides were applied in maize fields against the European corn borer. The experiments were conducted at two locations near Nitra in south-western Slovakia. The most efficient insecticides were pyrethroids Karate-2.5-EC and Decis-2.5-EC. A similar result was achieved with preparation Consult-100-EC (hexaflumuron) in 1993 and 1994. Bacillus thuringiensis formulations were as efficient as pyrethroids in 1993 and 1994, and not efficient enough in 1995. Time of application influenced the effectiveness of spraying with Bacillus thuringiensis preparations. The mortality of the European corn borer larvae was very low when treated by preparation Boverol (containing Beauveria bassiana spores). The best time for the European corn borer control was 10-14 days after the beginning of egg laying when the first damage to leaves was found on maize plants
