Les couverts végétaux. Un atout majeur pour réduire les intrants de synthèse et augmenter les services écosystémiques au vignoble

2020

International audience; De manière générale, un couvert végétal se définit par une espèce ou une communauté d’espèces végétales recouvrant le sol de manière permanente ou temporaire. L’agriculteur a la possibilité de semer ces couverts, selon un choix raisonné, ou bien de laisser la végétation spontanée se développer. Il existe 3 types de couverts semés avec des objectifs différents pour l’exploitant : le couvert hivernal, installé pour faire face au phénomène d’érosion du sol important pendant cette période de repos végétatif ; les engrais verts, installés avec l’objectif d’amender naturellement la parcelle, en détruisant et en enfouissant les résidus du couvert qui libèrent ainsi de la ma…

Updated pest categorisation of Xylella fastidiosa

2018

Abstract Following a request from the European Commission, the EFSA Plant Health Panel updated its pest categorisation of Xylella fastidiosa, previously delivered as part of the pest risk assessment published in 2015. X. fastidiosa is a Gram‐negative bacterium, responsible for various plant diseases, including Pierce's disease, phony peach disease, citrus variegated chlorosis, olive quick decline syndrome, almond leaf scorch and various other leaf scorch diseases. The pathogen is endemic in the Americas and is present in Iran. In the EU, it is reported in southern Apulia in Italy, on the island of Corsica and in the Provence‐Alpes‐Côte d'Azur region in France, as well as in the Autonomous r…

Exploit biodiversity in viticultural systems to reduce pest damage and pesticide use, and increase ecosystem services provision: the Biovine project

2019

International audience; Organic vineyards still rely on large external inputs to control harmful organisms (i.e., pests). The BIOVINE project aims to develop natural solutions based on plant diversity to control pests and reduce pesticide dependence. The capability of plants of increasing the ecosystem resistance to pests and invasive species is a well-known ecosystem service. However, monocultures (including vineyards) do not exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots) vineyards by planting selected plant species for the control of arth…

Validation of a mechanistic model for predicting fruit scab infection on different loquat cultivars

2017

[EN] Scab, caused by Fusicladium eriobotryae, is the main disease affecting loquat (Eriobotrya japonica) in the Mediterranean basin. A mechanistic epidemiological model developed in Spain to predict infection of loquat fruit by conidia was assessed in the main loquat cultivated area of Italy (Sicily). A 3-year study (2014-2016) was carried out in an experimental orchard on three loquat cultivars: Algerie, Peluche and San Filipparo. For each cultivar, output of the model was compared with observed scab development on fruits. The scab epidemics observed were different in different years and cultivars, representing a suitable data set for model validation. The model correctly predicted loquat …
