Each of us is carrying residues of pesticides in his or her body. More and more studies link immune system defficiencies, allergies and cancers with the chemicals which enter the human body via crops from non-organic agriculture. Students from the university of Valencia have now come up with an alternative, environmentally-friendly insect pest control method: the Sexy Plant.
Using controlled release of moth sex pheromones, the Sexy Plant causes mating disruption and avoid moth’s offspring. The team designed a genetic switch to turn on the release of pheromones after a solution of a copper-sulfate is sprayed on the plant. They also developed a biosafety module that prevents the plant to spread its genetic matter via pollen, which could eventually lead to an uncontrolled spread of the Sexy Plant itself which would endanger the original crop.

The Sexy Plant team claims that farmers can save up to 40% in insect pest control costs by planting the Sexy Plant between their crops. Plus, the pesticide free product can be sold for a better price. There is also a reduction in greenhouse gas emissions, since pesticides have a carbon dioxide footprint of around 3kg per hectare which is avoided when using the Sexy Plant.
