The idea of biological control is based on a pest management with deliberate using of antagonistic organisms. Inundative biological control has already successed and become an essential element of integrated pest management programmes. Some literature reports, as well as growers’ experience reveal that effective biological control methods of numerous pest species are available, and they can be easily used in practice, especially in greenhouses crops. According to the new Polish Plant Protection Act, biological methods should be used prior to any application of chemical products. Thus, biological control is now a priority in plant protection. Currently, the following biocontrol agents are recommended: three species of entomopathogenic nematodes (Steinernema feltiae, Heterorhabditis megidis, Phasmophrabditis hermaphrodita), only one biopesticides Preferal (Isaria fumosorosea), 33 species of beneficial organisms against pests and two biopesticides: Contans (Coniothyrium minitans), Polyversum (Pytium oligandrum) against diseases in greenhouses crops in Poland.
