Bionatrol, specified emulsion nano-particle soybean oil, as a non-toxic natural bio-insecticide and minimum risk pesticide (US EPA, Canada PMRA regulation), was evaluated by field tests for insecticidal efficacy on two spotted spider mites (Tetranychus urtiae), aphids (Aphid gossypii), and whiteflies (Trialeurodes Vaporariorum) on greenhouse grown English cucumber (Cucumis ssp. kasa). Bionatrol had a relatively high mortality rate against insects. Phytotoxicity did not occur when Bionatrol at 0.2 and 0.3% was applied with an air blast sprayer. Net CO₂ assimilation on cucumber leaves was not reduced when Bionatrol was applied at concentrations of 0.2, 0.3, and 0.5%, but it was reduced by 4-6% with Bionatrol at 1 and 2%.
