The vineyards are protected against the ravages of insects by using a technique known as ‘sexual confusion’

Pheromone diffusers are placed in the rows of vines to prevent chemical communication between the males and females. The chemical signal sent out by the female is distorted by the synthetic pheromones. The male doesn’t decode the message correctly and consequently doesn’t attempt to reproduce with the female.

The installation of this type of diffuser eliminates the need for mass spraying with insecticide which would settle on the grapes, it protects the production from pollution.
