Botanically derived insecticides have gained favour in recent years. They are more safe or natural. Also, they are comparatively safe to natural enemies and higher organisms. Neem, pyrethrum, rotenone, nicotine, sabadilla, ryania and a number of different available botanicals were used to protect agricultural crops from the ravages of insects, mites and nematodes in different parts of the world. In Egypt, experiments were carried out on the efficacy of neem seed kernel extract fractions and formulations against different pests. Promising results were obtained showing feeding deterrency, repellency, toxicity, sterilant and growth disruptive activities. However, few of these can be exploited as crop protectants. Those that are proven to have sufficient efficacy against pests in the field and can be produced in adequate quantities are suitable candidates for commercial development.
