Pick what you need to solve and see the most effective means.
Authorised means
Each means linked to the problems it solves and the tools that run it.
Copper
The essential contact fungicide against downy mildew, capped at 28 kg/ha over 7 years in the EU.
Sulfur
A mineral fungicide and acaricide, the base of powdery-mildew control without synthetics.
Bicarbonate & plant extracts
Potassium bicarbonate, oils and extracts as reinforcement and rotation in organic programmes.
Microbial biocontrol
Bacillus, Trichoderma, Aureobasidium and the like as part of the preventive organic programme.
Mating disruption
Pheromone dispensers saturate the air and prevent Lobesia botrana mating, without insecticide.
Beneficials & conservation
Conserving beneficials (predatory mites, parasitoids) with ecological infrastructure cuts the need to treat.
Mechanical weeding
Intercep tools, blades and brushes manage weeds in the row where herbicide is banned.
Green manure
A legume cover sown to fix nitrogen and be incorporated as a living fertiliser.
Authorised organic amendments
Compost, manures and amendments from the organic list supply slow-release nutrients.
Canopy management
Leaf removal and training that open the cluster zone and cut disease pressure — the baseline prevention.
Downy mildew control
The biggest challenge in organic viticulture — controlling downy mildew mostly with copper.
Powdery mildew control
A dry-weather disease, controlled mostly with sulfur and prevention.
Botrytis control
Grey rot prevented with airflow, cluster health and biocontrol.
Pest control
Grapevine moth and leafhoppers managed with mating disruption, beneficials and biocontrol.
Weed control
No herbicides — the row is managed by mechanical means, cover and mulch.
Nutrition & fertility
Feed the vine from the soil, without synthetic fertilisers.
Proof of compliance, without spreadsheets
GrapeFlow sums copper on the 7-year mean, logs every treatment by active substance and keeps the per-plot history — the proof organic certification demands.
