Based on knowledge of epiphytotic process in meloidogynosis the detailed recommendations for protection of soiling crops in bed and industrial greenhouses are provided. Symptoms and injuriousness in meloidogynosis of soiling crops growing in protected ground are presented. A schedule of epiphytotic process is provided and a schedule-based system of protection measures is suggested which includes quarantine measures, management methods and enables to foresee an impact on all stages of epiphytotic process. Protection measures carried out in bed greenhouses are based on using clean substrates, in industrial greenhouses – on using healthy sprouts, ensuring substrate level control, applying resistant varieties and hybrids, ravaging of weeds. When a nidus has been detected the following measures should be conducted to eliminate this nidus: to localize invasion and increase biological resistance of plants by all plying ameliorants (plant growth regulating agents), to disinfect ground using biogenic nematicides.
