A trap crop is a plant that attracts agricultural pests, usually insects, away from nearby crops. This form of companion planting can save the main crop from decimation by pests without the potential issues and controversy involved in using pesticides. Trap crops can be planted around the circumference of the field to be protected, or interspersed among them, for example being planted every ninth row.
