Sweet Potato – Alerts other plants

Sweet potato – This is a popular plant cultivated in the tropical zone, and came to Europe thanks to Christopher Columbus. Has no spikes or produces poison. It would seem that is defenseless against herbivorous insects. However, these appearances. New research shows that after its leaf is bitten, the batata produces a chemical substance. Which not only warns the rest of the plant, but also those adjacent to it. As a result of this alarm, plants produce chemicals that make them inedible for insects. Scientists say the discovery is the first step towards producing a natural, batata-derived pesticide.
