ABSTRACT
The use of pesticides plays an essential role to protect crops, food, commercial products, animal health and public health from different pests, in addition to their use in landscaping and industrial areas; but their use may lead to adverse effects on beneficial insects, wildlife, and the environment. Therefore, research for new technologies in agrichemicals and safer alternatives to pesticides became of public and scientific concern. Also, the adoption of organic agricultural farming may reduce the use of chemical pesticides and fertilizers but cannot replace intensive farming to produce enough quantity of food for the increasing population. Therefore, different types of allelopathic strategies might be used for weed management, maintenance of soil fertility, insect pest management, nematodes management, disease management and use of allelochemicals as growth regulators. Hence, this chapter covers the utilization of botanical pesticides in the control of crop pests (insects, weeds, nematodes, and pathogens).
