A survey was carried out to evaluate the size of the bio<strong>control</strong> market in Europe <strong>and</strong> to identify key<br />

factors that could influence its future evolution. This study included four main steps:<br />

- Localisation of the main crops <strong>and</strong> cropping systems.<br />

Using the data from EUROSTAT <strong>and</strong> national statistics a model of European agriculture was<br />

constructed.<br />

- R<strong>and</strong>omised sampling of farmers <strong>and</strong> retailers.<br />

The model was used for the selection of 12 production systems (Table 18) located on 25 sites in<br />

9 countries (Table 19) where 2000 farmers <strong>and</strong> 21 retailers were identified.<br />

- The selected sample was contacted by phone directly <strong>and</strong> a questionnaire (Table 20) was sent to<br />

those who agreed to participate in the survey. A total of 675 full responses were obtained <strong>and</strong><br />

analysed.<br />

- Complementary survey.<br />

In order to validate the process, more specific data was collected in a survey concerning the<br />

<strong>biological</strong> <strong>control</strong> of wood diseases of grapevine in France<br />
