Beneficials & conservation
Predators and parasitoids that regulate pests naturally.
Conserving beneficials is the foundation of biological pest control. Predatory mites (Typhlodromus), lacewings, parasitoids and others regulate populations of mites, leafhoppers and other pests without any insecticide.
The key is to create and protect habitat — ground cover, hedges, flower strips — and avoid broad-spectrum treatments that wipe out beneficials. It is a systems approach that strengthens over time and with vineyard diversity.
Effort
Low — mostly about not destroying the existing balance.
Cost
Low — it rests on habitat and good decisions.
Time to result
1–3 seasons for the balance to establish.

Pest control
Predators and parasitoids continuously regulate mites, leafhoppers and other pests, reducing or removing the need to treat.
Time horizon: 1–3 seasons
What to measure for this pairing
How it works
Stable populations of predators and parasitoids keep pests below the damage threshold, in a balance sustained by diversity and the absence of broad-spectrum treatments.
How to apply
- 1Keep cover and ecological infrastructure as habitat.
- 2Avoid broad-spectrum treatments that kill beneficials.
- 3Monitor the beneficial/pest ratio.
- 4Log observations to decide on thresholds.

Frequently asked
Do I need to release purchased beneficials?
Not always. In vineyards with good ecological infrastructure the beneficials are already present — the main thing is to conserve them. Releases can help in specific cases.
Does sulfur harm beneficials?
Sulfur can affect some predatory mites. Choosing tolerant strains and moderating applications helps preserve the balance.
