White grub damages various crops, trees and they can also be one of the most serious pests of turf grass in golf courses. This study was conducted to determine the biocontrol of white grubs with 18 different kinds (anise, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, and turpentine) of plant essential oils in laboratory, green house and field. Anise oil (88.9%), linseed oil (100%), and…
