Quels freins et leviers associés à l'utilisation de plantes de services pour réguler le puceron cendré en vergers de pommiers ?
Abstract
Fruit orchards are predominantly monospecific systems, whose limited plant diversity constrains the delivery of ecosystem services, particularly the natural regulation of pests. Introducing multifunctional service plants (herbaceous species, shrubs, or trees) offers promising opportunities to restore these functions by enhancing nitrogen inputs, supporting natural enemies, and increasing carbon sequestration. However, their adoption by growers remains limited because of uncertainties regarding their effectiveness and the changes in orchard management they require. A qualitative survey involving 34 apple growers from the two main French production regions (North-West and South-East) showed that vegetation diversification practices accounted for only 7.2% of the management options pontaneously mentioned by respondents, with aphid regulation being their primary objective (25% of the citations). Permanent ground cover, flower strips, and hedgerows were generally perceived as beneficial for natural enemies, but also raised concerns regarding pest control and vegetation management. In addition, participatory workshops involving researchers, advisors, and extension specialists identified several major barriers to adoption, including technical constraints (equipment suitability and crop management), economic limitations (additional production costs), organizational challenges (logistical complexity), and regulatory constraints, limiting pesticide use during flowering. The optimal use of service plants in orchards therefore remains to be defined, taking into account the diversity of production contexts. These findings highlight the need to develop on-farm experimental networks supported by common evaluation protocols that assess not only agronomic performance but also technical, economic and organizational dimensions. Such approaches are essential to produce knowledge that is both scientifically robust and relevant to growers' needs, thereby supporting the wider adoption of vegetation diversification in fruit orchards.
