AbstractPhytocompounds as insectides have gained momentum in modern insect pest management program due to the health hazards and perennial toxicity of conventionally applied noxious insecticides of different commercial brands. Turmeric plant produces fleshy rhizomes of bright yellow to orange colour in its root system, which are the source of the commercially available spice turmeric. Curcumin, which is a phytochemical with yellow colour turmeric, is used since time immemorial in most of the therapeutic practices. It is also used as a spice in foods, as a dye for fleece, and also as a component in nutritional supplements. In the form of root powder, turmeric is used for its flavouring properties as a spice, food preservative, and food-colouring agent. Turmeric has several therapeutic uses such as its antioxidant, antibacterial, anti-inflammatory, analgesic, and digestive properties. The fresh juice, the aqueous extracts, and the essential oil of the plant are credited with interesting pesticidal properties against certain pests of agricultural importance as well as a noticeable repellent activity against noxious mosquito species. Reports have shown an agreeable impending potentiality of turmeric as a natural pesticide for possible use in modern crop protection. So a highly promising future towards this direction is the possibility of effective control of certain pests of agricultural importance with the use of turmeric products as a cheap and more effective environmental friendly alternative to chemical pesticides.
