Controlled grass cover


  • Procedure  : Maintenance of a plant cover, natural or seeded, on the inter row and possibly the row
  • Phytosanitary interests :
    • The maintenance of a vegetal carpet on the inter row makes it possible to limit the use of herbicides.
    • Vegetation cover can also play the role of competing vegetation for the vine to limit its vigor and thus its susceptibility to diseases.
    • No direct effect on diseases
    • Induced effect: limits the development of diseases by limiting vigor (powdery mildew, gray and acid rots, mildew) 
  • Interests of the technique :
    • Adapt the quantity and quality of the harvest in relation to production objectives and soil water constraints
    • Level production from one year to the next
  • Induced effects :
    • Increase the quality potential of the harvest
    • Save on herbicides and pesticides (prophylactic effects by reduced vigor)
    • Improvement of the physical properties of the soil:
      • decompactant effect of root tissue, increased structural stability, porosity and permeability of the soil
      • better bearing capacity for machines: rapid intervention
    • Improve the biological properties of the soil: source of organic matter (burial of the canopy?), Increase
      biological soil life
    • Limit the development of mildew because: limitation of vigor, increase in evaporation in wet areas and "screen" effect which prevents primary contamination by splashing
    • Increase the sites for the auxiliaries according to the species of the cover in most cases, limit runoff and erosion phenomena (depending on the width of the grassy strip)
    • Limit product runoff
    • Promote biodiversity according to the species of cover (but some permanent grasslands sown can be poor in terms of biodiversity)
