The mating disruption technique is a very effective method for controlling lepidoptera. It consists of the homogeneous placement of female sex pheromone diffusers, which has been previously identified and synthesized. This creates an environment saturated with this pheromone and prevents the male from locating the female, thus preventing mating.
And since you do not need to apply any substance on the crop, there is no possible residue. Therefore, it is an environmentally friendly and innocuous method for handlers and consumers.
