摘要:
An estimate is made of the benefits resulting from the implementation of a proposed fungicide advisory programme for Kent wheat farmers. The programme has a value by providing information which enables improved spraying decisions to be made by farmers. The expected annual value for Kent is found to be £106,000.A closer examination is made of both the returns and costs of one component of the scheme, viz, the training of farmers to recognise the disease (caused by Septoria spp.) in their fields. An average benefit/cost ratio of 8/1 is calculated to result from the provision of farmer training programmes. However, if the decision by farmers to attend courses is made upon the criteria of expected gain to themselves, then initial courses would have a much higher benefit/cost ratio. There would be diminishing returns to additional courses, but only those Kentish wheat growers with the smallest areas of crop would lack the financial incentive to attend
