Maria Fidalgo, an affiliate professor in civil and environmental engineering on the University of Missouri, and a group of scholars and worldwide collaborators have give you a method to make use of sensors and movies to detect microscopic ranges of pesticide residue.

The group examined their system on tomatoes, in search of traces of the insecticide chlorantraniliprole.

“We chose the tomato because it was a good challenge,” Fidalgo mentioned. “One of the things we learned is that, because each vegetable has different nutritional values and chemical components, it can be quite tricky to understand how they interact with the sensor.”

Federal rules already require producers to make sure pesticide residue keep under sure ranges earlier than vegetables and fruit hit the produce aisle. That produce is examined in chemical labs. While the sensor may not be as correct as utilizing costly lab tools, Fidalgo’s group was capable of detect residue on the tomatoes at far decrease ranges than the tolerance degree established by the U.S. Environmental Protection Agency.

Although nonetheless in early phases, Fidalgo mentioned the tactic might sometime be commercialized to provide farmers an affordable choice for testing any fruit or vegetable.

“It could be a good tool for producers to check quality before selling their crops,” she mentioned. “They wouldn’t need to have a fully functional chemical lab, but rather a sensor and a very simple reading unit. It could be done in the field or by consumers concerned about residues.”
