Ex-post assessment of IPM solutions tested in experimental stations and farms and updates of database of alternatives to pesticides and IPM solutions

The overall sustainability of the baseline system, in the case studies observed during PURE, can be generally considered of good quality, ranging from “medium high” to “very high”. In many cases in fact, the baseline is already the actual application of IPM at the present and thus, a further improvement, may result in a gradual increase of the sustainability of the system only.

The innovative tools tested showed that, in general, an even improved environmental quality is possible keeping an efficient control of main diseases and pests studied in Grapevine activity.

Even if the application of the innovative approaches generally requested higher fixed costs, in most cases it resulted in a general reduction of the costs for disease management. The impact of the innovative IPM systems, in general, slightly modified the overall sustainability of the complete vineyard system.

In some cases (i.e. application of the DSS under Organic management regime), although environmental and/or economic aspects are modified, the DEXiPM_grape assessment doesn’t show any change in the global sustainability. This result could be explained by different reasons:

  • DEXiPM-Grapevine® was designed to assess a complete strategy and is not sensitive enough to be used for partial scenarios comparison (threshold values should be adapted for such a purpose). In the case of whole systems, however, this tool shown interesting results, mitigated by the fact that the reference used in some cases (Val de Loire) is already a durable system.
  • DEXiPM-Grapevine® is under development: a sensitivity analysis of the tool has to be conducted and implemented to validate the aggregation rules. A version 2014 of DEXiPM-Grapevine® is available at the end of the PURE Project with a data input manual.
