The dispenser

The photograph shows one of the tie dispensers impregnated with pheromones of the female vine moth.
This insect damages both the quality and the quantity of the grapes.
Continuous insecticide treatments were once required to eliminate it, but today the use of these dispensers attached to the canes prevents the moths from breeding.
We have been using this technology for a long time and have reduced the application of insecticides to a minimum.
