Dandelion uses latex to protect its roots against insect feeding

Dandelions are troublesome weeds that are detested by most gardeners. Yet dandelions also have many insect enemies in nature. However, they can protect themselves with their latex, a milky, bitter-tasting sap. Scientists have demonstrated that a single latex compound protects dandelion roots against voracious cockchafer larvae. Thus, latex plays a crucial role in dandelion defense against root feeders.
