These field trials were designed to study the effectiveness of various herbal interplantings and sprays in controlling insect pest populations of aphid, imported cabbageworm, and colorado potato beetle on the vegetable crops bell pepper, cabbage, and potato.  It has been concluded from the data collected, that a more intensive interplanting design is necessary to detect any effects which may occur due to an herbal interplanting or spray.
