Sulfur against pest control
The effectiveness, measured
Time horizon: 1 season
Why it works
Sulfur’s secondary acaricidal action helps keep mite populations in check without specific treatments.
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
- 1Start early, in the sensitive post-budburst phase.
- 2Apply with good coverage and renew as growth advances.
- 3Avoid applications in extreme heat (phytotoxicity).
- 4Respect the pre-harvest interval.
Frequently asked
Can sulfur cause phytotoxicity?
Yes, in extreme heat (above ~30–32 °C). Avoid applying in the hottest hours and during heatwaves.
Does sulfur also control mites?
It has a useful secondary acaricidal action against some mites, though that is not its primary purpose.
