An evaluation of plant protection practices according to IFP guidelines compared to current commercial practice.

The feasibility of integrated fruit production (IFP), as outlined by UK guidelines, was tested in the UK on apples during 1991-94. Control of scab [Venturia inaequalis] and mildew with IFP was as good as or better than that achieved by conventional production and often with reduced fungicide inputs and costs, particularly where the VENTEMTM scab warning system was used to assist in spray decisions. Similarly, control of the main insect pest, Adoxophyes orana, was improved in IFP compared to conventional production but with marginally increased insecticide use. Prediction of post-harvest rotting, based on pre-harvest assessment of rot risk in the orchard, indicated a low risk in each of the 4 years, which was subsequently confirmed by mean losses of <1% in untreated stored fruit assessed in March. Weed control in IFP, using contact herbicides, was also commercially acceptable. It is concluded that this study demonstrated the feasibility of IFP, but that increased management costs were usually req

uired to operate it.
