• Mildium
    • Decision support tool to limit the number of treatments
    • Mildew: 7 treatments max - 2 min, Oïdium: 5 max - 2 min
    • Plot decision indicators and acceptability of losses
    • Secure efficiency in the event of high parasite pressure
    • Reasoning the coupling / decoupling of mildew - powdery mildew

>>>> In the process of validation at the scale of the plot, a lot of observation time required

  • Variety creation
    • Identify disease tolerance or resistance genes in rootstocks or grape varieties
    • Risk of bypassing genes if monogenic resistance

>>>> For the moment at the research stage, not accepted at the social and legislative level

  • PNPP (Natural Preparations of Low Concern) prepared on the farm, these substances are used instead
    or in addition to conventional phytosanitary treatments
  • SDN (Natural Defenses Stimulator): substance that allows the plant to trigger at least one mechanism
    defense against a bio-aggressor (botrytis, mildew, powdery mildew for the moment)
    The elicitors come from various origins:
    • from living organisms (glucolipids, proteins),
    • Derived from plants by extraction or enzymatic degradation,
    • Various molecules such as salicylic acid, silica, certain fungicides (phosphonates, strobilurins), Bth
    • molecules currently sold as fertilizers and which would have eliciting or bio-fungicidal properties
      (their effectiveness in this regard remains to be demonstrated).
    • Only 1 elicitor approved on vines against powdery mildew, based on fenugreek

>>>> Brake: No approval standard specific to SDN or PNPP, little knowledge of their modes of action and their effectiveness

  • Spawning repellents
    • Kairomones mimicking cluster budworm egg saturation, prompting females to lay eggs elsewhere

>>>> Repellents patented in the 90s but no product available today

  • Biological control by conservation
    • Maintenance of favorable conditions for the establishment and development of natural predators of pests of the
    • Maintenance of ecological reservoir zones near the plots, choice of products according to their ecotoxicity

>>>> Lack of data on the impact of products on the populations of auxiliaries, on the role of auxiliaries on the expected product savings 

  • Inter cultures nematicides
    • Put in place during the rest of the soil before replanting the vine. Their implantation would prevent disinfection
      chemical soil to fight against the court-knotted.
