L'esprit du Château Lafon-Rochet a toujours été l'apport de nouvelles stratégies de lutte afin de réduire les intrants phytosanitaire. Cette étude a l'objectifs de suivre le Mildiou sur des parcelles en biodynamie. En plus nous avons comparé plusieurs produits naturels tels que Botector®, Armicarb® et Serenade Max® pour voir leur efficacité dans la maitrise du champignon Botrytis cinerea. Des mesure de la vigueur et de la compacité des grappes ont été faites afin de mettre en évidence une différentes sensibilité intra- et inter-parcellaire vis-à-vis des maladies cryptogamiques. Le millésime 2013 a été très favorable au développement du Mildiou et du Botrytis, alors qu'un nombre élevé de traitements ont été effectués. L'IFT (indice de fréquence de traitement) comptabilise le nombre de doses homologuées utilisées par hectare et par campagne et il permet donc d'évaluer la « pression phytosanitaire» exercée sur chaque parcelle. L'impact des traitements phytosanitaires sur le bilan économique n'est pas négligeable. Alors qu'une analyse des coûts a été effectuée par les différentes stratégies de lutte. Les résultats montrent que, concernant le millésime 2013, la sensibilité des vignes a été influencée plus par le terroir que par les différentes stratégies de lutte. En revanche le poids au niveau économique est bien différent selon le type de stratégie mise en place.
The spirit of Chateau Lafon -Rochet is to find new strategy to reduce the plant inputs. This study had the following objectives: mildew on parcel in biodynamic viticulture. In addition we have compared several natural products such as Botector®, Armicarb® and Serenade Max® to see their effectiveness in the mastery of the fungus Botrytis cinerea. Measurements of the vigor and compactness of clusters have been made to highlight a different sensitivity intra -and inter- compartmental opposite the fungal diseases. The year 2013 was very favorable to the development of mildew and Botrytis, while a large number of treatments have been effectiveness. The IFT (treatment frequency index) counts the number of approved doses per hectare per year and therefore evaluates the ¿pest pressure¿ on each plot. The impact of the plant treatment on the economic results are not negligible. While a cost analysis has been done by different strategy . The results show that for the 2013 year, the sensitivity of the vines was more influenced by the soil by different control strategies. In contrast, the impact at the economic level is very different depending on the type of strategy implementation.

Abstract
The spirit of Chateau Lafon -Rochet is to find new strategy to reduce the plant inputs. This study had the following objectives: mildew on parcel in biodynamic viticulture. In addition we have compared several natural products such as Botector®, Armicarb® and Serenade Max® to see their effectiveness in the mastery of the fungus Botrytis cinerea. Measurements of the vigor and compactness of clusters have been made to highlight a different sensitivity intra -and inter- compartmental opposite the fungal diseases. The year 2013 was very favorable to the development of mildew and Botrytis, while a large number of treatments have been effectiveness. The IFT (treatment frequency index) counts the number of approved doses per hectare per year and therefore evaluates the ¿pest pressure¿ on each plot. The impact of the plant treatment on the economic results are not negligible. While a cost analysis has been done by different strategy . The results show that for the 2013 year, the sensitivity of the vines was more influenced by the soil by different control strategies. In contrast, the impact at the economic level is very different depending on the type of strategy implementation.File | Dimensione | Formato | |
