SUMMARY An integrated programme of pesticides and biological agents was used for the control of cucumber pests at seven sites in England in 1970. Tetranychus urticae was effectively controlled using the predacious mite Phytoseiulus persimilis . The parasite Encarsia formosa gave variable control of Trialeurodes vaporariorum. Tyrophagus longior was controlled by sprays of parathion applied to the beds or straw bales before planting at five of the six sites where control measures were used, and bed drenches of gamma‐BHC or diazinon gave good control of Thrips tabaci . When used in this way, these pesticides did not aifect the biological control programme. The selective aphicide pirimicarb was used to control Aphis gossypii . Dimethirimol controlled cucumber powdery mildew early in the season but later applications gave control at only one site.
