Canopy management against pest control
The effectiveness, measured
Time horizon: 1 season
Why it works
Leaf removal exposes clusters and larvae, improves biocontrol reach and hampers moth development.
What to measure for this pairing
Why this problem matters
The main pests — the grapevine moth (Lobesia botrana) and leafhoppers — are managed organically without synthetic insecticides. The moth opens wounds that are an entry point for botrytis, tying pest control to disease control.
The tools are pheromone mating disruption, conservation of beneficials (predators and parasitoids) and authorised products such as Bacillus thuringiensis. Trap monitoring and action thresholds avoid needless interventions.
Problem indicators
Certification & rules: Mating disruption and biocontrol are pillars of integrated production and organic status.
How to apply the means
- 1Remove leaves in the cluster zone after fruit set.
- 2Manage vigour and canopy height to open the canopy.
- 3Favour morning-sun-side leaf removal in hot climates.
- 4Log operations and the effect on disease risk.
Frequently asked
Doesn’t leaf removal expose clusters to sunburn?
In hot climates, yes, if excessive or on the afternoon-sun side. Moderate, morning-side leaf removal balances health and sunburn protection.
Does canopy management replace treatments?
It does not replace them, but it greatly cuts pressure and the number of treatments needed — the prevention that makes the organic programme viable.
