Application of biological agents to protect cucumber plants against multiple pests in greenhouses in Northwest Russia

Abstract

Dynamics of the main pests of cucumber over a five-year period were analysed. The impact of meteorological conditions on the pest dynamics was observed when growing photo culture cucumbers in a greenhouse all year round. The possibility of successful and efficient use of cotton aphid, spider mite, tobacco thrips, greenhouse whitefly and noctuid moth entomophagous was demonstrated. Application rates for several entomophagous were proposed for prevention and protection of cucumber plants against the above-mentioned pests.
