Abstract
Synthetic insecticide is a promising tool for controlling insect pests globally but have negative impacts such as residual toxicity, insect resistance development, effects on non-target organisms and other adverse environmental impacts. For sound management of pests, there is an increasing interest in biotic control using plant products and its derivatives, which is eco-friendly with highly reduction in those impacts. Botanical insecticides such as neem, nicotine, pyrethrum, rotenone etc, are used universally having both biochemical and biophysical properties against insect pests. Pyrethrum and Neem including essential oil are well established commercially. Azadirachtin, bioactive compound of Neem shows insecticidal properties like antifeedant, repellent, ovipositional deterrent, fecundity reduction and longevity. Quick knockdown effect of Pyrethrum and various nerve poison compounds like nicotine in tobacco are very effective in pest management. Using powdered and extract products from plants for small scale farmer is feasible due to its simple application process, less residual and toxicity.
